OT / IACS Cybersecurity
Security that respects how operations actually run.
Operational technology environments carry constraints IT frameworks were never written for: safety cases, vendor-locked systems, decades-long asset lifecycles. TRYGG brings hands-on OT and IACS experience, applying IEC 62443 and Australian critical infrastructure obligations in ways plant and operations teams can live with.
