Something doesn’t add up. The OT security industry is spending $282 billion a year on mitigation. Cybercrime is projected to cost industrial organisations $10.29 trillion globally by 2025. And, according to a 2025 report from Fortinet, 31% of industrial organisations now report six or more intrusions per year. The investment is going in. The losses […]

OT asset discovery is the process of identifying and understanding the industrial devices, systems, and connections operating within an operational technology (OT) environment. This includes control systems, networked equipment, and supporting infrastructure that directly or indirectly influences physical processes. One of the earliest decisions organisations face is whether OT asset discovery should be handled internally,
OT asset discovery provides a snapshot of what exists in an operational environment at a given moment. Asset visibility, however, is not static. Industrial environments change continually, often in small and incremental ways that are easy to overlook. Maintaining OT asset visibility over time means ensuring that asset information remains accurate, current, and useful long
OT asset discovery is only useful if the results can be understood, trusted, and acted on. The reporting is where discovery either becomes operationally valuable or remains a technical exercise. 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,

OT asset discovery software is designed to identify, catalogue, and maintain visibility of devices and systems operating within industrial environments. Its primary role is to provide a structured view of what exists on OT networks, how assets communicate, and, in some cases, what risks may be present. Unlike IT asset tools, OT-focused software is built
OT asset discovery is a foundational activity for understanding risk, resilience, and operational dependencies in industrial environments. In practice, it is rarely straightforward. Operational technology environments tend to be complex, long-lived, and shaped by operational priorities rather than documentation or visibility. This creates a set of recurring challenges that can limit the accuracy or usefulness
OT asset discovery is most effective when it is done at the right moment, not treated as a one-off technical exercise. In operational environments, timing determines whether discovery supports good decisions or simply produces an incomplete snapshot. This article explains when OT asset discovery should be carried out, the typical triggers that prompt it, and
Operational technology (OT) environments depend on a wide range of devices, systems, and software working together reliably. Knowing what is present in those environments is a prerequisite for security, resilience, and safe operation. Two related terms are often used interchangeably: OT asset inventory and OT asset discovery. They are closely linked, but they are not
Operational technology (OT) environments are not static. Devices are added, firmware is updated, configurations drift, and network behaviour changes as processes evolve. In the real world, these changes usually occur incrementally and without a single clear transition point. Which means that whilst a one-off OT asset discovery exercise is great for establishing your existing security
Passive OT Monitoring and Continuous Asset Discovery Read Post »
OT asset discovery is only effective if its scope reflects how industrial environments actually operate. Focusing on a narrow set of devices can leave significant gaps in visibility, risk understanding, and operational awareness. A meaningful OT asset discovery exercise should account for all assets that influence the behaviour, availability, and security of operational systems —
What Assets Should be Included in OT Asset Discovery Read Post »
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.

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.
