Manufacturing & Industrial Cybersecurity

Operational Technology (OT) security protects industrial control systems (ICS), SCADA, PLCs, and HMIs that manage physical manufacturing processes. Unlike IT security, OT breaches can cause physical damage, production shutdowns, and safety hazards. According to Dragos' 2024 OT Cybersecurity Report, 72% of OT vulnerabilities are exploitable remotely - making specialized OT security essential for every manufacturer.

We use passive network monitoring and non-intrusive scanning techniques specifically designed for industrial environments. Our OT security assessments follow IEC 62443 standards, analyzing network traffic, device configurations, and access controls without sending active probes to sensitive PLCs or SCADA systems. This ensures zero disruption to production lines while identifying critical vulnerabilities.

The Purdue Model is a reference architecture that segments industrial networks into hierarchical zones - from Level 0 (physical processes) to Level 5 (enterprise network). Proper implementation prevents attackers from moving laterally from IT networks into OT environments. We design and implement network segmentation aligned with the Purdue Model using next-gen firewalls and DMZ architectures.

For unpatachable legacy systems, we implement compensating controls: network segmentation isolates vulnerable devices, virtual patching through IPS/IDS protects known vulnerabilities, and continuous monitoring detects exploitation attempts. Our Managed SOC monitors OT networks 24/7 with analysts trained in industrial protocol analysis (Modbus, DNP3, OPC UA).
