In practice, it is rarely that simple.

From what we see working with customers, renewal is usually part of a larger process. It involves multiple steps, and if something is missed, it can lead to warnings or even downtime.

Why frequent renewal is now required

SSL certificates no longer last for 398 days.

As of March 2026, certificates can be issued for up to 200 days. This is shorter than before, and it is getting shorter.

The idea is simple. Shorter lifespans reduce risk. If something goes wrong, it limits how long a certificate can be misused.

In reality, many organisations are already moving to even shorter cycles. This is usually supported by automation.

From experience, teams that still manage certificates manually tend to struggle more as these timelines get shorter.

Renewal ensures:

• The website remains secure
• Continued browser trust
• Certificate details remain up to date

Here is what happens behind the scenes:

Step 1: Creating a new request

 When a certificate is renewed, the system will usually generate a new security key.

This key is kept private. It is what protects the connection between the website and its visitors.

A request is then created using this key. This is often called a certificate request.

It contains basic details about the website, along with a public version of the key.

In most environments, generating a new key is considered good practice. It reduces the risk of older keys being reused over time.

Step 2: Checking your identity

Next, the Certificate Authority needs to confirm that you still control the domain.

This is an important step regardless of the issuing Certificate Authority. It prevents someone else from requesting a certificate for your website.

For Domain Validation, this can be quick.

You might be asked to do any of the following:

• Approve an email sent to your domain
• Add a DNS record
• Upload a small file to your website

For Organisation Validation, there are more checks.

These may include verifying your business registration and confirming your company details.

For Extended Validation, the checks go even further. The Certificate Authority will review your organisation more thoroughly.

Step 3: Issuing the new certificate

Once everything is verified, the certificate is issued.

You will receive a few files. Each one plays a role in establishing trust.

These include:

• Your main certificate
• Intermediate certificates
• The root certificate (already trusted by browsers)

Together, they form what is called a certificate chain.

If this chain is not set up properly, browsers may show warnings even if the certificate itself is valid.

There is also something happening in the background that most people do not see.

New certificates are recorded in public logs. This adds an extra layer of transparency, allowing browsers and security systems to detect suspicious or unauthorised certificates.

Step 4: Installing the certificate

The new certificate then needs to be installed.

This usually means replacing the old certificate and making sure the full chain is configured correctly.

In smaller setups, this might be straightforward.

In larger environments, it can be more complex. Certificates may need to be updated across multiple servers, load balancers, or cloud services.

This is where we often see issues. A certificate is renewed, but not deployed everywhere it needs to be.

When someone visits your website, their browser runs a series of checks.

This happens in seconds.

The browser will:

• Check that the certificate is valid
• Confirm it has not expired
• Verify the issuing authority
• Match it to the domain

It will also validate the full certificate chain.

When an SSL certificate expires, the connection is no longer secure, resulting not only in downtime, but also in exposing systems to potential cyber threats and causing reputational damage. This is why timely renewal is critical.

A quick note on automation

With shorter certificate lifespans, manual processes become harder to manage.

This is why many organisations are moving towards automation.

In most modern setups, certificates can be requested, renewed, and installed automatically in the background.

From what we see, this significantly reduces missed renewals and operational overhead.

Automation helps to:

• Renew certificates on time
• Handle shorter validity periods
• Reduce manual errors

Solutions like Next-Generation SSL are designed to manage this centrally.

Instead of tracking certificates individually, teams can monitor and manage everything in one place.

Final thoughts

SSL renewal is not just a routine task.

It is something that needs to be managed continuously.

As environments grow, manual handling becomes difficult to maintain. This is where many teams start to feel the strain.

More organisations are now treating certificates as part of their ongoing security operations, rather than as something handled only occasionally. If your team is facing similar challenges, it may be worth looking at how an automation solution like Next-Generation SSL can help to simplify operations and reduce risk.

Together, they’re disruptive.

The first is well known: quantum computing is moving from theoretical research into practical engineering. Whether we think it will take 5 years or 15, one thing is clear: the public key algorithms protecting today’s internet were not designed for a quantum-capable adversary.

The second is more immediate and operational: the CA/Browser Forum has formalised the progressive reduction of SSL/TLS certificate validity periods, culminating in a maximum lifespan of 47 days by 2029.

Forty-seven days.

That’s not a typo.

If you run a public website, APIs, cloud workloads, or anything customer-facing, this isn’t just a compliance detail. It’s an operational shift.

Why This Combination Is Different

Let’s break it down.

1. The Post-Quantum Shift Is About Crypto Agility

Most organisations are not worried about quantum computers breaking RSA tomorrow.

What they should be thinking about is this:

When PQC becomes production-ready and mandated, how fast can you transition?

If your certificate infrastructure is rigid, manually managed, and scattered across business units, then the real risk isn’t quantum; it’s organisational inertia.

Crypto agility is not about deploying PQC today.

It’s about ensuring you can switch when the time comes.

2. 47-Day Certificates Change the Operating Model

For years, certificate management was treated as an administrative task. A renewal reminder here, a spreadsheet there.

That model doesn’t survive a 47-day validity world.

At 47 days:

• Renewals become constant
• Manual tracking becomes error-prone
• Outage risk increases exponentially
• Audit and compliance complexity grows

Shorter lifespans are good for ecosystem security.

But they demand automation.

The Real Issue Isn’t PQC. It’s Lifecycle Management.

Based on what we observe across industries, the real bottleneck isn’t algorithm readiness.

It’s visibility.

Many organisations don’t have:

• A complete inventory of their SSL/TLS certificates
• Centralised expiry monitoring
• Automated issuance and renewal workflows
• A structured plan for algorithm transition

And without those fundamentals, talking about post-quantum migration is premature.

You can’t modernise cryptography if you don’t even know where it’s deployed.

What Forward-Looking Organisations Are Doing

The more mature organisations we observe are taking a phased approach:

Step 1: Gain Full Certificate Visibility

Build a complete inventory across public websites, internal systems, cloud, containers, and load balancers.

Step 2: Automate the Lifecycle

Move away from manual renewals. Integrate issuance and renewal into DevOps and infrastructure pipelines.

Step 3: Design for Algorithm Flexibility

Ensure that certificate management systems are not tightly bound to a single algorithm. Prepare for hybrid (classical + PQC) deployments when standards stabilise.

Step 4: Monitor Industry Signals

Track NIST PQC standardisation, browser support, root program policies, and regulatory guidance to be prepared.

A Subtle but Important Shift

Historically, SSL/TLS certificates were treated as point-in-time security artefacts. From now on, they need to be treated as continuously managed cryptographic assets.

The 47-day timeline accelerates this.

The post-quantum era makes it non-optional.

Final Thought

The organisations likely to struggle in the PQC transition are not those lacking quantum expertise.

They’re the ones still managing certificates manually.

If there’s one practical takeaway from both trends, it’s this:

Before thinking about quantum-safe algorithms, make sure your certificate lifecycle is automated, visible, and crypto-agile. Everything else builds on that foundation.

SSL/TLS encrypts data in transit, but it does not guarantee end-to-end Confidentiality, Integrity and Authenticity (CIA) once the email message reaches intermediate systems or the mail servers.

To have a secure email is to ensure that all sensitive information remains guarded throughout its entire lifecycle, from the moment it is sent out by the sender till the recipient opens it. With the increase in remote work, more stringent regulatory requirements and a growing number of data breaches, organisations must move beyond SSL/TLS encryption to achieve higher email security postures.

We will explore why SSL/TLS alone is never enough, and how organisations can strengthen email security postures by using comprehensive encryption strategies.

Many believe that once email traffic is protected by SSL/TLS, the communication is secure. However, in reality, SSL/TLS only encrypts the part where the email is being transmitted between mail servers. So, once the email reaches a server, it will typically be decrypted and stored in plain text, making it vulnerable to attacks such as internal threats, compromised mailbox or server breaches.

A straightforward example would be sending a confidential letter in a locked courier truck and leaving it unsealed during storage in a warehouse. If adversaries gain access to the server, or if the emails are forwarded, archived or backed up, the original SSL/TLS encryption no longer applies.

As organisations increasingly exchange sensitive information such as contracts and financial data, only relying on SSL/TLS exposes them to compliance risks and data leakage. A stronger, more holistic email encryption approach is needed to address these gaps.

1. End-to-End Email Encryption

Emails will be encrypted at the sender’s side, and remain encrypted till decryption is done by the recipient. This will ensure only the intended recipient can decrypt and read the email content, preventing others, including mail servers, from accessing the email content.

Modern email encryption solutions can integrate seamlessly with common platforms like Outlook and Gmail. For external recipients who do not use the same encryption system, secure methods such as email verification or one-time passcodes can be used to authenticate the recipient and allow secure decryption through a browser.

By encrypting the email message itself, rather than just the transmission channel, organisations can ensure total confidentiality of the email message from sender to recipient. This significantly reduces exposure to server-side breaches and insider threats.

2. Encryption at Rest

Data at rest, such as archives and backups require encryption as well, to prevent attackers from gaining access to the mail server or storage system. This encrypted data remains unreadable without the proper keys for decryption.

3. Identity-Based Encryption and Key Management

A combination of Identity-Based encryption, centrally managed key systems, and hardware security tokens to simplify key management. Associating keys with user identities while storing private keys in USB tokens that cannot be replicated will help to prevent unauthorised decryption and support secure user onboarding and offboarding.

4. Secure Email Gateways and Policy Enforcement

Secure email gateway solutions with built-in Data Loss Prevention (DLP) capabilities help organisations enforce encryption policies automatically. These systems can inspect email content and apply encryption based on predefined rules.

For example, emails containing personal data (PII) or financial information can be automatically encrypted before being sent, whether to internal or external recipients. This reduces reliance on users to make security decisions and ensures consistent protection across the organisation.

Best Practices / Tips

• Classify sensitive email content so encryption policies are applied automatically and consistently.
• Encrypt emails both in transit and at rest to cover the full data lifecycle.
• Secure external communications by integrating a third-party application for encrypted email exchanges with partners and customers with ease and usability.
• Centralise key management to reduce complexity and minimize human error.
• Audit and review DLP policies regularly to align with evolving threats and compliance requirements.

Lastly, and the most important point:

• Educate employees on the importance of email security to prevent data leakage.

These recommended practices help organisations to maintain a strong email security posture without burning out users or IT teams.

Conclusion

SSL/TLS is an important foundation for email security, but it is no longer sufficient on its own. Organisations must adopt strong encryption strategies that protect data end-to-end, at rest and across all email workflows. With comprehensive encryption, organisations can reduce breach risks, strengthen compliance and build trust in digital communication.

The post Why Enterprises Need Secure Email Encryption appeared first on Netrust.

On 11 April 2025, the CA/Browser Forum — the industry body that governs SSL/TLS certificates — voted to progressively shorten certificate validity periods. The end point: a maximum of 47 days by 2029. The first milestone already hit this month.

For a change, I’m not writing this to sell or promote anything. I’m writing this because I’ve been in the PKI and digital security space for a long time, and I’ve seen how these kinds of changes catch organisations off guard when they’re buried in forum announcements and technical documentation that most business leaders never read.

So here’s the plain-English version.

What changed, and when

Previously, organisations can obtain an SSL/TLS certificate valid for up to 398 days — a little over 13 months. That’s the window you have before you need to renew.

Under the new schedule approved by Apple’s proposal at the CA/Browser Forum, that window shrinks significantly:

The first cut — to 200 days — applies from 15 March 2026. That’s now.

If your organisation is renewing or issuing new certificates from this point forward, you’re already operating under the new rules.

Why did this happen?

The reasoning is sound, even if the timing creates inconvenience. Shorter certificate lifespans reduce the window of exposure if a certificate is ever compromised. If an attacker gets hold of a certificate, a 47-day lifespan limits how long they can exploit it.

There’s also a push to get organisations away from manual, ‘set it and forget it’ approaches to certificate management — which, frankly, most organisations still rely on.

The industry is essentially forcing automation. The question is whether your organisation is ready for it.

What this means at the leadership level

Most of us as leaders are not the ones managing certificates day to day. That sits with your IT or security team. But the decisions that come out of this change will land on your desk — because the response options each carry trade-offs that go beyond the technical.

The math is straightforward. If your organisation manages 50 certificates today and renews them once a year, that is roughly 50 renewal actions annually. At 47-day validity, the same estate requires close to 400 renewal actions a year. Some teams, when they hear this, immediately ask: can we just hire more people to handle the increased frequency?

It is a fair instinct, but it misses the real problem. The issue is not volume alone — it is complexity and visibility. Certificates are often reused across multiple systems. It is not best practice, but it happens, and it happens a lot. When that is the case, a single certificate expiring does not just affect one service. It can cascade across everything it was deployed to — and the team may not even know where all the instances are.

Most certificate-related outages I have seen are not due to malicious/lazy administrators. They happen because a certificate was tracked in a spreadsheet or an internal document, got buried in a long list, and either was missed entirely or was renewed in one place but not updated everywhere it was deployed. Adding headcount to a manual process does not eliminate that risk — it just means more people are working from the same incomplete picture.

The question to ask your team is not “do we have enough people?” It is “do we have full visibility of every certificate we own, and do we know everywhere each one is deployed?” If the honest answer is no, that is the gap to close first.

My own experience trying to automate this

I want to share something candidly, because I think it is more useful than giving advice I have not personally tested.

Netrust is not a large organisation. We are not a bank with a dedicated security operations team of fifty people. And even so, pushing for automation internally has not been straightforward. Automating anything requires people to change how they work — and change is uncomfortable, even when everyone agrees it is the right direction. There are internal inertias to work through, legacy processes to untangle, and moments where it feels easier to just keep doing things the old way.

I share this not to paint a bleak picture, but because I think leaders who are navigating this need to go in with realistic expectations. Automation is the right answer. Getting there requires someone at the top to hold the line on it — because the path of least resistance will always be to patch things manually and move on.

Interestingly, a recent review with my team surfaced something worth noting. It is actually the smaller, more nimble organisations that are showing the most eagerness to move on this. Perhaps because they have fewer legacy systems to untangle, or because the decision chain is shorter — but whatever the reason, they are not waiting. If anything, that should give the larger organisations pause.

If you are a CIO or CISO reading this, this is your initiative to champion — not to delegate and forget. The organisations that will handle the 2027 and 2029 milestones well are the ones where someone at the leadership level decided early that manual was not good enough.

What good looks like

The answer is not a product — it is a capability. The organisations that will navigate this well are the ones that have moved from reactive to systematic. Certificates should not be something your team scrambles to deal with. They should be something your infrastructure handles on its own, with your team only stepping in when something genuinely needs attention.

When I think about what that looks like in practice, I would ask four questions of any approach your team puts forward:

• Can we see every certificate we own, across every system, in one place — without someone having to compile a spreadsheet?
• Does renewal happen automatically, well before expiry — or does the process only start when someone notices a reminder?
• When a certificate is renewed, is it updated everywhere it is deployed — or just in the place someone remembered to check?
• If something looks anomalous or falls outside policy, does the team find out proactively — or after something breaks?

If the honest answer to any of those is “we are not sure” or “it depends on who is on duty” — that is where the conversation with your team needs to start. This is not just a technical decision. It is an operational resilience decision. The CIO or CISO who surfaces this to the board before something breaks is in a very different position from the one who has to explain an outage.

Signing off — for now

I have been speaking with peers across sectors — education, government, financial services — and the pattern is consistent. Most organisations know something is changing. Not many have sat down to work out what it actually means for their environment, their team, and their processes.

I am happy to share my own journey on this — the decisions we made, the pitfalls we hit, what I would do differently — over coffee or when we cross paths at industry gatherings. These are the conversations I find most useful, and I suspect others do too.

Till the next time we meet.

The post Your SSL Certificates Are About to Expire a Lot More Often. Here’s What That Means for Your Organisation. appeared first on Netrust.

In real-world environments, certificate renewal may seem completed from the issuing CA’s perspective. This does not guarantee successful provisioning, which may result in application failures, service outages, or authorisation issues. Such issues might not be detected immediately. They are usually detected only after a service or server restart activity or routine maintenance. This adds more pressure to the maintenance team for remediation.

The cause of the certificate renewal failure is usually not due to the certificate itself. They are caused by dependencies around keys, permissions, trust chains and system integration. This post shares some of the common reasons for the certificate renewal failure and what teams should pay attention to when the certificate renewal is operated at scale.

The complexity behind certificate renewal

In theory, certificate renewal sounds straightforward: replacing an expiring certificate with a new certificate.  However, certificates in enterprise environments usually contain dependencies. They are tied to private keys, service identities, HSMs, load balancers, databases, and multiple downstream systems.

Renewing a certificate not only updates the certificate information. A new key pair may be generated, permission may be re-evaluated, or the trust chain may differ, especially when the issuer changed. Those changes do not always cause immediate failure, and this makes them more difficult to detect during routine checks.

Common Causes of Certificate Renewal Failures

1. Key Pair Changes Are Not Fully Understood

A very common cause for the failure is whether the renewal reuses the existing key pair or generates a new one. This distinction matters, especially during the troubleshooting phase.

When a certificate is used for encryption, signing or database protection, changing the key pair can have downstream effects. Data encrypted with the old key still requires the old key for operation and accessibility. In an environment where an HSM is used to store the private key, key lifecycle management becomes even more crucial due to strict access controls and policies.

2. Private Key Access Breaks After Renewal

It is not uncommon for certificates to renew successfully while applications fail to access the private key afterwards. This often comes down to service accounts, identity mappings, or permission changes that occur during renewal.

These issues frequently appear only after a restart or failover, when services attempt to rebind to the key. At that point, troubleshooting becomes more difficult, especially in production environments with tight recovery timelines.

3. Trust Chain Differences Are Overlooked

If the full trust chain isn’t updated across the environment, renewed certificates may fail validation. Client or upstream components may reject the certificate even if this certificate is technically valid.

This is a very common issue in environments where Strict TLS validation is imposed, or where multiple network layers, such as load balancers and reverse proxies, exist.

4. Automation Focuses on Issuance, Not Validation

In large environments, automation services usually focus on certificate issuance. While logs may confirm a successful renewal, they do not verify that the application has successfully adopted the updated certificate. A mandated post-renewal validation should be in place. This process checks the active binding, key access, or live TLS handshakes. Those issues may remain hidden until the next operational event triggers a failure.

5. Renewals Are Not Tested Under Operational Scenarios

Certificate renewals are usually validated only under normal conditions. During failovers, patching exercises or disaster recovery, it is usually overlooked or tested superficially.

As a result, the certificate renewal process that seems reliable during day-to-day operation may fail when the system is under stress. These are precisely the moments when certificate-related issues cause the most impact.

Practical Considerations for Enterprise Teams

From an operational perspective, a few practices consistently help reduce renewal-related issues:

• Be explicit about whether renewals reuse existing keys or generate new ones.
• Always verify private key access after renewal, not just certificate presence.
• Ensure intermediate certificates and trust chains are deployed consistently.
• Monitor both renewal status and deployment success.
• Test renewals during restarts, failovers, and planned maintenance windows.

These steps do not eliminate complexity, but they significantly reduce surprises.

Conclusion

In the enterprise environment, certificate renewal is rarely due solely to expired certificates. They are usually the result of hidden dependencies across keys, permissions, identities and trusted chains. Automation helps, but it does not replace the need for visibility and validation. At least for now.

When a certificate renewal is managed as part of a full lifecycle rather than as background tasks, outages can be reduced, avoided, and prevented. This becomes more important as the enterprise environment scales and increases in complexity. In addition, with the shortening of the TLS certificate to 47 days, the renewal frequency increased significantly. This greatly reduced the response time for manual intervention, ad-hoc troubleshooting or operational error. As such, a more robust automation, proper lifecycle management and end-to-end validation should be in place for the certificate renewal process. Contact us today for a consultation today.

As organisations become more dependent on PKI (Public Key Infrastructure) for their day-to-day activities, setting up and maintaining their on-premises PKI to manage certificates can be a complex and demanding task over time. PKI is no longer limited to a few use cases like encrypted email or network access. Instead, PKI is now used to secure a wide array of technologies, including mobile devices, the Internet of Things (IoT), DevOps, and a growing number of API-connected services.

What Are the Challenges of On-premise-Based PKI

High Cost of ownership. On-premises PKI requires a significant upfront investment of resources in software/hardware systems (such as servers and hardware security modules), physical facilities, and skilled PKI staff to design, operate, and secure the PKI infrastructure.

Operational and Security Risk. As organisations expand their use of PKI, the on-premises PKI can become increasingly difficult to manage over time. This is often due to the deployment of multiple certificate authorities (CAs), which can lead to operational overhead and security risks, with no clear ownership of who is responsible for managing the CAs. This situation can result in misconfiguration, human errors, and delays in applying critical updates to address vulnerabilities.

Manual Certificate Lifecycle Management On-premises PKI lacks integrated automation, monitoring, reporting, and alert notification. This means that manual processes must be used to manage large numbers of certificates. Manually monitoring and managing high volumes of certificates is highly inefficient and susceptible to errors.

Lack of Scalability. As an organisation’s PKI expands to include more users, devices, and applications, the number of certificates to manage can increase exponentially. On-premises PKI solutions lack the scalability to accommodate this growth, often requiring extensive planning, significant resources, and substantial hardware investments to expand infrastructure. Failure to scale out, the PKI infrastructure becomes a bottleneck, slowing down operations and impacting user experience.

Considering the above challenges of on-premises PKI, a cloud-based PKI solution simplifies the deployment process and lowers the cost of implementing PKI. Additionally, a cloud-based PKI approach allows organisations to more easily expand the use of PKI to meet evolving business needs.

What is PKIaaS

Public Key Infrastructure as a Service (PKIaaS) is a cloud-based PKI service that provides functions of public key infrastructure (PKI) without the need to build or manage the PKI infrastructure. By outsourcing costly investment in PKI infrastructure, the time-consuming and resource-demanding task of managing a PKI in-house to a PKI provider, PKIaaS reduces the operational complexity and cost associated with managing PKI infrastructure.

Benefits of PKIaaS

PKIaaS offers numerous benefits to organisations:

Reduced costs: PKIaaS can help organisations save on initial and ongoing costs by eliminating the need to purchase and maintain the hardware, software, and skilled personnel required for PKI infrastructure. Instead, PKIaaS offers these services through a monthly subscription fee, which makes the costs much more predictable, as the various hidden and in-house expenses associated with running a PKI are replaced by a flat-rate billing model.

Increased Operational efficiency:  PKIaaS offers a centralised view of the entire PKI operations, providing organisations with control over all their certificates under a consistent policy framework. This centralised management approach helps reduce the time and effort needed for administrative tasks, minimise human errors, and streamline compliance checks. As a result, organisations can experience a substantial improvement in their overall operational efficiency.

Increased resiliency. PKIaaS solutions are designed with redundancy and failover capabilities, utilising geographically distributed data centres. This ensures that the PKI solutions remain continuously available in the event of a system failure. Implementing redundancy and failover capabilities can be challenging and costly for most organisations on their premises.

Increased security compliance. PKIaaS ensures the security of an organisation’s PKI by operating the PKI infrastructure with industry best practices and compliance requirements such as GDPR, HIPAA, and PCI DSS. This helps to minimise and manage any potential security risks. Additionally, PKIaaS rapidly delivers consistent updates to critical software patches and ensures adherence to the latest security policies and procedures, thereby providing a secure and current PKI solution.

Highly scalable: PKIaaS can rapidly scale its services to accommodate the evolving needs of an organisation, without any additional investment in hardware or software. With PKIaaS, organisations can create multiple certification authorities in a matter of minutes, rather than weeks or months.

Automated Certificate Lifecycle Management. PKIaaS simplifies certificate management from issuance to renewal and revocation by automating the deployment and lifecycle of certificates issued to devices or users via standard protocols and APIs. This substantially reduces the time and effort dedicated to manual processes, and also minimises the possibility of human mistakes.

Manage PKI Operations with PKIaaS

PKIaaS platforms are designed to provide a centralised platform that acts as a single view for all PKI activities, from deploying Certificate Authorities (CAs), monitoring, reporting, to managing all certificates issued from the CAs with the following key features:

Deploy a multi-tiered Root/Subordinate certificate authority (CA) trust hierarchy and offer multiple certificate types such as TLS certificates, S/MIME or code signing. Core PKI services, such as CRL (Certificate Revocation List) and OCSP (Online Certificate Status Protocol), are provided to facilitate certificate validation.

Automation support for certificate lifecycle management.

Detailed views of certificates across CAs. Acts as a single source of multiple CAs and views the status of all certificates.

Reporting and monitoring. Generate reports on certificate usage, expiration and monitor the operational health of PKI components.

Enforce policies. Establish and apply uniform security policies for all certificates across the entire organisation, including key length, certificate profiles, and access controls. This will help mitigate the risks associated with human errors and misconfiguration.

Role-Based Access. Assign tasks to various teams, granting them specific permissions to ensure that only authorised individuals can carry out particular PKI-related activities.

Automate Certificate Management with PKIaaS

PKIaaS is highly automated in managing the lifecycle of certificates. When a certificate is nearing its expiration date, PKIaaS automatically renew the old certificate and issues a new one, ensuring a seamless transition and distribution of the updated certificate.

The PKIaaS turnkey integration solution offers organisations a variety of options to automate the distribution and administration of certificates, including:

• Microsoft certificate autoenrollment protocols (WSTEP) for Windows Active Directory users and computers.
• ACMEv2 (Automatic Certificate Management Environment) to automate certificate management for web services or APIs.
• SCEP (Simple Certificate Enrolment Protocol) and MDM (Mobile Device Management) to automate certificate management with Routers, firewalls, IoT communication, Microsoft Intune, Google MDM, VMware Workspace ONE and Jamf MDM.
• RESTful API-driven automation to integrate with third-party or custom applications for various use cases such as TLS/mTLS certificates for containers orchestration systems and DevOps tools.

With Certificate Enrolment Gateway (CEG) services, PKIaaS platforms support standard certificate enrolment protocols like SCEP, ACME, or MDM. The CEG acts as a gateway connecting with protocols such as WSTEP, SCEP, ACME, MDM, and RESTful API to accept certificate requests from endpoints and then transmit them to the cloud-hosted Certificate Authority (CA) to automate the management of the certificate lifecycle.

In Conclusion 

PKI plays a critical role in ensuring secure digital communication, a strong authentication mechanism and data protection within the organisational environment. However, efficiently managing a PKI solution can be challenging due to the associated costs and complexities involved in supporting and securing the PKI infrastructure.

With a PKIaaS (PKI as a Service), organisations no longer need to handle the complex tasks of setting up, configuring, and managing their own PKI infrastructure. PKIaaS is designed to be highly scalable, allowing it to grow with demand, continuously monitor the PKI environment, and automate certificate lifecycle management. This enables organisations to improve the security and efficiency of their PKI.

Considering the benefits of PKIaaS, it is advisable to evaluate implementing a PKIaaS solution within your organisation. If you have any questions about PKIaaS, please don’t hesitate to contact the Netrust Sales team at https://www.netrust.net/contact-us/  to find out more.

The post Simplifying PKI infrastructure with PKIaaS appeared first on Netrust.

What Is Certificate Provisioning?

Think of it this way: you’re handing out secure passes to your servers and devices so they can talk safely. You create the certificates, pass them out, and keep them up to date. That’s provisioning.

It protects data, verifies legitimacy, and maintains privacy. Plus, if you do it right, you’re not stuck fixing things later cause someone forgot to renew something.

1. Automate Certificate Requests with ACME Protocol

The ACME (Automatic Certificate Management Environment) protocol made the renewal of SSL/TLS certificates automated. The common implementation of ACME is Let’s Encrypt, which provides free certificates to people who need them.

Certbot is a tool from ACME, it can automatically request and install certificates without the need for manual intervention. This is the step to set up for the web server (example, Apache or Nginx):

• Install Certbot: This is the official ACME client for Let’s Encrypt. It’s supported for various platforms (Linux, macOS, Windows).

sudo apt install certbot

• Request a Certificate:

With the command, Certbot can automatically request a certificate and configure our web server for HTTPS:

sudo certbot –apache -d example.com

Certbot will handle the entire process:

• • Verifying your domain ownership
  • Requesting the certificate from the CA (Certificate Authority)
  • Installing and configuring the certificate on your server
• Automatic Renewals: Certbot automatically generate renewals, so we won’t have to worry about certificates expiring. A cron job or systemd timer can be set up to renew the certificate before it expires.

sudo certbot renew –quiet

This is an ideal solution for provisioning certificates for web services and APIs, ensuring your servers always have valid, up-to-date certificates without manual intervention.

2. Use a Centralised Certificate Management System (CMS)

For larger environments, particularly those with multiple servers, web services, appliances, and applications, managing certificates individually can become challenging and time-consuming. This is where a Centralised Certificate Management System (CMS) comes into play.

CMS tools such as DigiCert CertCentral, and Venafi allow you to:

• Store and manage all of your certificates in one place
• Automate certificate renewal and deployment
• Monitor certificate health and expiration
• Ensure compliance with organizational security policies

How it works:

• DigiCert CertCentral: With DigiCert, you can automate certificate provisioning across your infrastructure, whether it’s for web servers, appliances, or IoT devices. It also provides APIs for integrating certificate provisioning into your workflows.
• Venafi: Venafi offers enterprise-scale automation for certificate provisioning, helping large organisations manage the lifecycle of millions of certificates across servers, appliances, cloud instances, and other endpoints.

Using a CMS makes things easier, without the complexity and manual intervention, it enables centralised monitoring and auditing, providing security teams with a streamlined, scalable solution.

3. Leverage Cloud Provider’s Managed Certificate Services

Cloud providers like AWS, Google Cloud, and Azure offer managed SSL/TLS certificate services to simplify provisioning for services hosted in the cloud.

• AWS Certificate Manager (ACM): AWS ACM allows you to easily provision, manage, and deploy SSL/TLS certificates for your domains and services running in AWS. ACM automates the process of requesting, installing, and renewing certificates, and integrates seamlessly with AWS services like Elastic Load Balancing, CloudFront, and API Gateway.

To request a certificate in AWS:

aws acm request-certificate –domain-name example.com –validation-method DNS

• Google Cloud Certificate Manager: Google Cloud offers a managed solution for SSL/TLS certificates. It integrates with Google Cloud services like Load Balancing and API Gateway. With Google Cloud’s Certificate Manager, you can automatically request and deploy certificates with a few clicks or API calls.
• Azure Key Vault: Azure provides an integrated solution for managing and provisioning SSL certificates via its Key Vault service. This tool allows you to secure and manage the certificates used by Azure services, such as App Services, and provides easy automation for renewal.

Each of these services offers robust API access, allowing you to programmatically request and manage certificates, automate renewals, and integrate with your DevOps pipelines.

4. Provision Certificates to Appliances and IoT Devices

Many enterprises have appliances or IoT devices need secure communications but lack the capabilities of web server or cloud service. For these devices, a more manual provisioning method is needed, although it can still be streamlined with the right tools.

• Use Device Certificate Management: Tools like IoT Identity Management or X.509-based Certificate Authorities can be used to provision certificates to IoT devices. These systems allow you to issue unique certificates for each device, which can then be securely distributed and installed using device management platforms.
• Secure Boot and Key Management: Some appliances and edge devices come with secure boot functionality that ensures that only trusted certificates are used for communications. You can pre-install certificates during the device manufacturing process or provision them over secure channels using automation tools like Ansible or Puppet.

5. Implement Certificate Revocation and Monitoring

It’s essential to have a way to monitor the status of your certificates and revoke them when necessary. Automating this process ensures that expired or compromised certificates don’t remain in your infrastructure, exposing you to potential vulnerabilities.

• Use OCSP (Online Certificate Status Protocol): Implementing OCSP allows servers to check whether a certificate has been revoked in real-time. It’s typically built into most modern browsers, but you can also set up OCSP responders for your infrastructure.
• Centralised Logging and Alerts: Tools like Elastic Stack or Splunk can help monitor certificate expiration dates, renewal failures, or any suspicious activities related to certificate usage.

Conclusion

Managing SSL/TLS certificates across various servers, web services, appliances, and applications aren’t exciting, but it doesn’t have to be overwhelming. By using the right automation tools, centralised management platforms, and cloud-based services, you can maintain a secure infrastructure without the hassle of manual certificate handling.

With automated solutions like ACME clients (e.g., Certbot), centralised management systems (e.g., DigiCert CertCentral, Venafi), and cloud-native services (e.g., AWS ACM, Azure Key Vault), you can streamline the entire certificate lifecycle, reduce the risk of human error, and shift your focus back to building and deploying your services.

The Need for Continuous Monitoring

There are two main types of periodic and continuous security monitoring. Although both try to detect danger, the approach and result vary significantly.

• Periodic Monitoring requires periodic reviews. Though useful, this method tends to have blind spots between reviews, during which threats can develop undetected.
• Continuous Monitoring, on the other hand, operates 24/7. By flagging anomalous activity as it occurs, it enables teams to take prompt action and stop possible breaches.

Depending on sporadic monitoring only is like locking your door tonight and leaving it open tomorrow in a world of the internet, where threats are constantly changing.

The Flaw of Traditional Monitoring

Below are some of the limitations of conventional security monitoring techniques:

• Laudable threats are lost due to slow reaction.
• No visibility on events in real time hinders decision-making.
• There is a human mistake in manual procedures.
• Threat non-detection is possible if threats go unrecognised on a timely basis.

A company is at risk of business disruption, data loss, and legal issues due to these issues.

What to Get out of a Continuous Monitoring Solution

Simple notices are no longer good enough for businesses today. The following are the secrets to successful certificate monitoring solutions:

• Automated Threat Detection that uses machine learning to identify oddities in real-time.
• Real-Time Alerts that rapidly escalate problems to the impacted teams.
• Compliance support for standards such as NIST, GDPR, and ISO 27001.

• Centralised Dashboards to present end-to-end views of risks and certificate status.
• Seamless Integration with cloud platforms, SIEM solutions and IT tools.

What is Certificate Enrolment?

Certificate enrolment is the process of requesting and obtaining a digital certificate from the Certificate Authority (CA). The enrolment process typically involves the requester generating a key pair, creating a certificate signing request (CSR) containing the public key and identity information, sending it to the certificate authority (CA), and finally receiving the signed certificate from the CA.

The Challenge of Managing Multiple CAs

Most enterprises utilise certificates from multiple certificate authorities (CAs) to serve different purposes. One CA for public-facing TLS/SSL certificates, another for internal PKI needs, and yet another CA for special needs like code signing certificates or device authentication. This segmentation could pose numerous pain points:

• Different interfaces and workflows for different CA
• Redundant management interfaces and administrative overhead
• Exposed to a higher risk of certificate-related outages
• Inconsistent policy enforcement
• Limited cross-CA visibility and incomplete certificate inventory

What is Centralised Enrolment?

Centralised enrolment is a key feature of Certificate Lifecycle Management (CLM) that unifies the process of managing digital certificates across multiple certificate authorities (CAs). Whether the CAs are internal, public or cloud-based, centralised enrolment brings certificates together in a single platform. It acts as an intermediary between certificate requesters and CAs, ensuring a smooth and standardised enrolment process.

Key components of centralised enrolment:

Centralised Certificate Enrolment Portal

A single interface where users or administrators can request digital certificates regardless of the target certificate authorities (CAs). This eliminates the redundancy of navigating through different interfaces for each certificate authority (CA).

Centralised Certificate Request

Transforms certificate requests into specific formats to accommodate different Certificate Authorities (CAs). It facilitates communication with various CAs using their native protocols, ensuring a standardised enrolment process.

Consistent Policy Enforcement

With centralised enrolment, organisations can implement consistent security policies across all certificates. Moreover, it can enforce standardised requirements such as key lengths, cryptographic algorithms and validity periods before forwarding requests to the certificate authorities (CAs). This consistent policy enforcement reduces security risks associated with improperly configured certificates.

Centralised Inventory

A centralised certificate inventory provides complete visibility of all certificates, including certificate request status, metadata, etc. No more wondering which certificates belong to which CA, everything is in one centralised location.

 CA Flexibility

Centralised enrolment enables organisations to gain independence from individual CA providers, thereby providing organisations with the ability to choose or switch certificate authorities (CAs) based on their specific strengths or organisational needs.

With the ever-growing usage of digital certificates across various domains and use cases, managing certificate authorities (CAs) will only become more complex and challenging. Centralised enrolment presents a pragmatic solution to address this challenge by offering a unified space to manage all certificate authorities (CAs), consolidating request processes, standardising security policies, and offering a centralised certificate inventory. This transforms certificate management from a series of disconnected, redundant tasks into a streamlined, centralised and automated process.

Centralised enrolment is part of the Certificate Lifecycle Management (CLM) solution, which Netrust offers. Contact us at https://www.netrust.net/contact-us/  to find out more.

In the new digital age, there is a huge dependence on digital services. Organisations are forced to prioritise SSL certificate renewals to maintain secure and uninterrupted operations. Manual renewal processes often lead to lapses, causing the website to go down and rendering services unavailable. Ensuring efficiency in certificate renewal remains a key challenge, especially with an organisation’s growing number of digital assets. Automating certificate renewals is becoming increasingly essential for organisations to ensure security and business continuity.

In addition to traditional certificate management concerns, organisations must now consider Post-Quantum Cryptography (PQC) and the growing need for crypto-agility. As quantum computing advances, organisations must ensure their cryptographic infrastructure is agile enough to adapt to future security requirements.

Challenges of SSL Certificate Renewal

Managing SSL certificate renewal can be a time-consuming challenge for many organisations, particularly those with numerous certificates across different environments. Some common challenges include:

• Manual Tracking Issues – Organisations struggle to keep track of where certificates are deployed and when they expire.
• Outdated Algorithms – Certificates with outdated algorithms are still in use and expose organisations to cyber threats.
• Operational Disruptions – Unexpected certificate expiration can cause service downtime, adversely affecting business reputation.
• Scalability –Managing an increasing number of SSL certificates manually becomes impractical.

Best Practices for Streamlining SSL Certificate Renewal

To address these challenges, these are some best practices that organisations can work towards implementing:

• Automated Certificate Discovery – Set up scheduled scans to discover and inventorize certificates within the organisation.
• Enable Automated Renewal Alerts – Set up notifications and alerts to proactively manage expiration dates.
• Centralize Certificate Visibility – Utilise a single dashboard to track all certificates across different Certificate Authorities and different environments.
• Prepare for Crypto-Agility – Ensure your certificate management system is agile enough to replace outdated algorithms with ease.

Tools for SSL Certificate Lifecycle Management

For better efficiency in SSL certificate renewals, organisations can leverage Certificate Lifecycle Management (CLM) solutions that help to automate and streamline certificate management processes. Netrust offers a wide range of advanced CLM solutions, available as on-premise or software-as-a-service, with capabilities to support multiple CAs, both public and private.
