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.

‘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.
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.
