Penetration Testing for Energy & Utilities
Energy and utility companies operate critical infrastructure that underpins society, including power generation, electricity distribution, gas networks, water treatment, and renewable energy systems. These organisations face threats from nation-state actors, cybercriminals, and hacktivists targeting operational technology (OT) systems that control physical processes.
The convergence of IT and OT networks has created new attack vectors, with compromises of IT systems potentially providing pathways to industrial control systems. Penetration testing for energy and utilities must address both IT infrastructure and OT/SCADA systems, requiring testers with specialised expertise in industrial protocols and safety-critical environments.
Testing must be carefully planned to avoid disrupting essential services and must comply with sector-specific regulations including NIS 2 in Europe and NERC CIP in North America. The increasing deployment of smart meters, distributed energy resources, and IoT sensors across energy networks further expands the attack surface and testing requirements.

Energy & Utilities Pen Testing FAQs
Can live OT/SCADA systems be safely pen tested?+
Yes, but with extreme care. Experienced ICS pen testers use passive techniques on live systems and may use offline replicas for active testing. Safety protocols and rollback plans are essential.
What regulations govern energy sector pen testing?+
NIS 2 (EU), NERC CIP (North America), and national energy regulators set cybersecurity requirements. Many require regular security testing of both IT and OT systems.
How do we test IT/OT convergence points?+
Testing should examine network segmentation between IT and OT, data diodes, historian servers, jump servers, and any systems that bridge the IT/OT boundary. These convergence points are critical attack paths.
