OT security
Operational technology runs the physical world: the PLCs, SCADA, DCS, safety systems and building controls that move water, power, freight and product. It was built for safety and uptime, often decades ago, and it is now connected to IT, the cloud and remote vendors. The ASD warns that OT and the systems that support it are now prime targets for malicious actors. Our OT risk assessment follows IEC 62443-3-2. We build an accurate inventory using passive methods, partition the system into zones and conduits, assess risk by consequence (safety, environment, production and compliance) and set a target security level for each zone. You get a prioritised, costed plan that engineers and the board can both act on.
OT security
Zones and conduits with target security levels, and the first fix marked.
OT security
Agree the sites, systems and safety rules, and plan the traffic capture with operations.
Passive traffic capture, configuration reviews and walkdowns, on site in agreed windows.
Inventory, zones and conduits, threat scenarios and target security levels.
Findings for your engineers, a summary for the board, and the roadmap to act on.

OT security
No live scanning of controllers. We rely on passive traffic capture, configuration reviews and walkdowns agreed with your operations and safety teams. Any active testing is optional, agreed separately and done in maintenance windows.
