Written by Melissa AngMay 21, 2026Many people think renewing an SSL certificate is just a quick click. 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
Written by Eng Jing WeeMay 7, 2026These days, almost everything relies on cryptography in one way or another, whether it is SSL/TLS, digital signing, identity systems, or encryption. But when people talk about security, they usually focus on the algorithm or the technology itself. What often gets overlooked is something much more practical: how the keys are managed. Because no matter how strong the encryption is, if
Written by Tommy GohApril 23, 2026If you looked at my calendar right now, you would see a colourful Tetris-like board of Teams meeting links, RFP deadlines, and site visit reminders. People often ask what a “Presales Consultant” actually does. In short, I’m the bridge between a “cool idea” and a technical reality that actually works. At Netrust, my client base focuses on Singapore and the wider
Written by Edwin LeeApril 9, 2026There are two things happening in the SSL/TLS world right now that, in isolation, are manageable. 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
Written by Kai Yong WongMarch 25, 2026Email remains one of the most widely used communication channels in the present enterprise environment and one of the most commonly targeted by attackers. While many organisations solely rely on SSL/TLS for protection of their email traffic, secure email encryption actually is more than just transport-layer protection. SSL/TLS encrypts data in transit, but it does not guarantee end-to-end Confidentiality, Integrity and
Written by Eugene Lam – Deputy CEO, NetrustMarch 17, 2026Earlier this year, a decision was “quietly” made that will create real operational headaches for most organisations — and a lot of people haven’t noticed yet. 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
Written by Guo JieMarch 12, 2026With certificate automation, renewal is no longer a concern for the enterprise. The assumption is that this service, once configured, will renew certificates quietly in the background and will continue to work as expected. Unfortunately, this case is not always true. In real-world environments, certificate renewal may seem completed from the issuing CA’s perspective. This does not guarantee successful provisioning, which
Written by Lai Yong XingFebruary 26, 2026Are you trying to implement or are you trying to understand Encryption from scratch? Or does your brain feel like scrambled eggs after trying to understand how S-boxes work in the AES algorithm with GCM mode? In this article, we aim to explain Encryption by using real life objects and examples to bridge the concept to reality. Let’s start with a
Written by Charles HuangFebruary 12, 2026Guest Contributor, Charles Huang, Co-Founder & COO of Scantist In today’s digital-first world, the line between application development and AI integration has vanished. While this fusion drives innovation, it also creates a complex and expanded attack surface. How can organizations protect their software without slowing down progress? The answer lies in a unified approach to application security. Traditional, siloed tools are
