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.

SCADA/ICS Penetration Testing FAQs
Is it safe to pen test live SCADA/ICS systems?+
Testing live production systems carries risk. Experienced ICS pen testers use passive techniques on live systems and may use lab environments or digital twins for active exploitation. Safety is always the top priority.
What qualifications should ICS pen testers have?+
Look for testers with ICS-specific certifications like GICSP, knowledge of industrial protocols, and demonstrated experience in OT environments. General pen testing certifications alone are not sufficient.
How often should ICS/SCADA systems be tested?+
Annual testing is recommended as a minimum, with additional testing after significant changes to the OT environment or when new threats emerge targeting your industry sector.
