OT security
Operational technology moves water, power, gas, fuel, freight and product, and it is increasingly connected to IT networks, the cloud and remote vendors. The ASD warns that OT and the systems that support it are now prime targets, and in June 2026 the enhanced SOCI Act rules raised the bar for operators of the highest-risk critical infrastructure.
Our OT practice works with your engineers, not around them. We start with a passive inventory and a consequence-based risk assessment, design zones and conduits to IEC 62443, secure remote and vendor access, and prepare you for audit and the SOCI deadlines.

Yes. In OT, safety and availability come first, systems run for decades, patching needs outage windows and an aggressive scan can upset a controller. The principles are similar, but the methods must respect the process. That is why we start passive and agree every step with operations.
