OT threat detection for a regional energy utility

The Challenge

The utility faced blind spots across substation control networks and ageing SCADA assets, requiring passive monitoring that could not disrupt live operations.

Key Issues:

• Unmonitored SCADA protocols
• Ageing, unpatchable control assets
• Flat IT and OT convergence
• No baseline of normal plant behaviour

The Solution

We deployed passive OT sensors, mapped every control asset, and built behavioural baselines that flag anomalies without process risk.

Key Actions:

• Passive substation network sensors
• Full asset inventory across the control estate
• Behavioural anomaly baselines per site
• Segmented IT and OT boundaries

You cannot defend a plant you have never fully mapped. Visibility comes first, and every meaningful control decision afterwards depends upon it.

Compliance & Risk Management

Critical infrastructure operators face regulatory scrutiny alongside genuine safety consequences. Our OT programme documents asset ownership, network boundaries, and detection coverage, giving NERC CIP auditors clear evidence while engineers keep generation running safely.

• Critical infrastructure operators face regulatory scrutiny alongside real safety consequences.
• OT Asset Visibility – Passive discovery across every substation and control network.
• Network Segmentation Design – Enforced boundaries between corporate and plant zones.
• Anomaly Detection & Response – Behavioural alerting tuned to industrial protocols.
