Energy and utility companies operate critical infrastructure that is essential to national security and public safety. Power grids, water treatment facilities, oil and gas pipelines, and renewable energy systems face threats from nation-state actors, hacktivists, and ransomware gangs targeting operational technology (OT) and SCADA systems. Regulations including NERC CIP for the electric sector mandate specific cybersecurity controls. The convergence of IT and OT networks, aging infrastructure, and remote monitoring capabilities create complex attack surfaces.
