Your OT security posture is not determined by your own controls alone. It is determined by the ability of every critical supplier in your chain to keep their production running. And the weakest link in that chain is almost certainly not you.
Your OT security is only as strong as your weakest supplier Read Post »
The OT security industry is spending $282 billion a year on mitigation, but industrial organisations now report six or more intrusions per year. The investment is going in. The losses are going up. So what’s going wrong?
Why spending more on OT security isn’t making manufacturing safer Read Post »
‘OT asset inventory’ and ‘OT asset discovery’ are often used interchangeably. But they are not the same thing, and treating them as equivalent often leads to gaps in visibility and misplaced confidence.
OT asset discovery is most effective when it is done at the right moment. Timing determines whether discovery supports good decisions or simply produces an incomplete snapshot.
OT environments can be complex, long-lived, and shaped by operational priorities. This creates recurring challenges that can impact asset discovery efforts if they are not addressed deliberately.
Unlike IT asset tools, OT-focused software is built to operate safely around industrial protocols, legacy equipment, and environments where availability and safety take priority over visibility.
Good OT asset discovery reporting translates raw observations into a clear picture of what exists, how it connects, and why it matters. It supports security, operations, and risk decisions without overwhelming the reader or introducing unnecessary complexity.

In ever-changing industrial environments, maintaining OT asset visibility over time means ensuring that asset information remains accurate, current, and useful long after an initial discovery exercise has been completed.
One of the earliest decisions organisations face is whether OT asset discovery should be handled internally, delivered by an external specialist, or shared between the two. Each approach has strengths and limitations that are important to understand.
Operational technology environments are not static. So, whilst a one-off OT asset discovery exercise is great for establishing your existing security profile, passive OT monitoring combined with continuous asset discovery is much better at maintaining an up-to-date view of what is present and how it behaves, without interfering with operations.

A meaningful OT asset discovery exercise should account for all assets that influence the behaviour, availability, and security of operational systems — not just the most visible control equipment.

OT systems are not usually designed to be scanned or interrogated aggressively. So how do you achieve meaningful OT asset visibility without introducing operational risk? The answer lies in understanding the difference between passive and active OT asset discovery.
IEC 62443 is one of the most established frameworks for improving the security of operational technology and industrial control systems. In this article we explain IEC 62443 in simple terms, clarify what it means for SMEs, and demonstrate how it can be adopted in a manageable, phased way.

Operational Technology (OT) is the backbone of modern industry. As these systems become more connected to digital networks, gaining a deeper understanding of OT is essential for both business leaders and engineers.
John Allen, Strategic OT Security Director at Harpoon Consulting, looks at the unique challenges that manufacturers face when it comes to implementing a successful OT cybersecurity programme.
Cyber threats are no longer just an IT problem. They’re hitting the plant floor too. So we’ve put together a set of smart, simple steps small manufacturers can take towards better OT security, without breaking the bank.
