OT / ICS &
Critical Infrastructure
Operational technology can't be tested like a corporate network: the wrong scan can take a plant offline. We assess the systems behind energy, water and transport using passive, non-intrusive techniques built for how fragile and high-stakes these environments are.
- Passive asset discovery for SCADA, DCS, PLCs and HMIs
- IT/OT network convergence security with protocol-aware inspection
- Low-noise anomaly detection engineered around established OT baselines
- Compliance with AESCSF, NIST CSF and IEC 62443
- Purdue model segmentation enforcement
- Hands-on OT and critical-infrastructure security assessment
Common Questions
Can you safely scan an OT network?
We don't active-scan fragile OT environments by default - the wrong probe can take a PLC or an entire process offline. Discovery is passive: listening to traffic, not interrogating devices. Anything active is agreed explicitly and tested in a maintenance window.
What is IEC 62443?
The international standard family for securing industrial automation and control systems - ISA/IEC 62443. It covers zones, conduits, and security levels for OT environments, and our assessments align to it.
Do SOCI Act obligations apply to us?
If you operate critical infrastructure - energy, water, transport, health, telecommunications and more - quite possibly. The Cyber and Infrastructure Security Centre administers the regime. We help you work out whether you're captured and what your CIRMP needs to contain.
