SCADA/ICS Penetration Testing Providers

SCADA/ICS penetration testing evaluates the security of industrial control systems, supervisory control and data acquisition (SCADA) systems, and operational technology (OT) environments. These systems control physical processes in critical infrastructure including power generation, water treatment, oil and gas, manufacturing, and transportation.

Testing requires specialised expertise as ICS/SCADA environments use different protocols (Modbus, DNP3, OPC, BACnet), have unique safety requirements, and often run legacy systems that cannot tolerate aggressive testing techniques. ICS pen testers assess network segmentation between IT and OT environments, the security of human-machine interfaces (HMIs), programmable logic controllers (PLCs), remote terminal units (RTUs), and engineering workstations.

Testing identifies vulnerabilities that could allow attackers to manipulate physical processes, cause safety incidents, or disrupt operations. ICS/SCADA pen testing follows specialised frameworks and standards including IEC 62443, NIST SP 800-82, and NERC CIP. This testing is increasingly critical as OT environments become more connected to IT networks and face growing threats from nation-state actors and cybercriminals targeting critical infrastructure.
