OT Security Articles

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.

OT asset discovery is the first step in understanding and securing your operational systems, ensuring you know what you’re protecting, where your risks lie, and how to prioritise improvements.

The European Union’s NIS2 Directive is transforming how organisations approach cybersecurity. We take a look at what’s in the directive and what it means for industrial organisations – particularly the small players.

Security frameworks are the most effective way to approach ICS security systematically. From Nis2 and NIST CSF, to IEC 62443, and ISO 27001, they provide structure and help organisations implement repeatable security processes.

For many SMEs, OT security can feel like a complex or distant topic. In this article, we explain what OT security means, why it matters, and how industrial businesses can take practical steps to build a secure foundation.

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.

OT security is a highly complex field that needs specialist attention. But a complex security strategy drains resources, extends timelines, puts pressure on business budget. The solution? A simple, structured approach that optimises security while reducing costs and implementation time.

Many manufacturers are using digital transformation to increase efficiency, enable greater productivity, and reduce production costs. But those new technologies bring with them increased cybersecurity risks. Not taking them into account can be catastrophic for small businesses.

OT security has a reputation for being complicated. Many organisations think that putting in place a simple plan isn’t enough to safeguard their operations. But simplifying OT security doesn’t mean cutting corners. It just means focusing on what matters, in a straightforward, no-nonsense way.
