Is Your OT Network Really Isolated? Why Trust Isn’t Enough

Cyber SecurityWritten by Kai JalonenJuly 30, 2026
Guest Contributor, Kai Jolonen, Head of Sales and Business Development, Asia-Pacific of SensorFu   Is Your Operational Technology(OT) Network Really Isolated? Why Trust Isn't Enough When we think about protecting Singapore's critical infrastructure—our power grid, water supply, transport systems, manufacturing plants and healthcare services—we often assume that these systems are safely separated from the internet and corporate networks. But what if

Why Post-Quantum Cryptography Matters Today

Cyber SecurityWritten by Ong Zhen YuJuly 2, 2026

A while back, I was explaining encryption to my colleague and used this analogy: “Your data today is locked inside a really strong safe.” That’s still true, but here’s the part people don’t think about: What if someone is already copying that same safe and is waiting for the day they can open it?   That’s essentially what’s happening with quantum

Rethinking Development in the Age of AI

Cyber SecurityWritten by Lin Jian ShengJune 4, 2026
From Search Engine to AI: A Developer’s Journey Through Changing Paradigms As a developer in my 40s, I have seen how our way of working has evolved over the years. Back then, solving a problem usually meant opening Google and going through multiple tabs—Stack Overflow threads, API documentation, random blog posts, trying different approaches until something finally worked. It was often

Security Key Management: The Backbone of Digital Trust

Cyber SecurityWritten by Eng Jing WeeMay 7, 2026

These 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

High Stakes and Digital Trust: My Reality as a Netrust Presales Consultant

Cyber Security, LifeWritten by Tommy GohApril 23, 2026

If 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

The 47-Day Certificate Era and the Post-Quantum Reality: Are We Ready?

Cyber Security, SSL CertificatesWritten by Edwin LeeApril 9, 2026

There 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

Why Enterprises Need Secure Email Encryption

Cyber Security, SSL CertificatesWritten by Kai Yong WongMarch 25, 2026

Email 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
