ETSI EN 303 645 for Energy
Power companies, oil and gas operators, water utilities, and renewable energy providers manage critical infrastructure that underpins society. Here is how ETSI EN 303 645 helps energy organisations build and maintain compliance.
Why ETSI EN 303 645 Matters for Energy
Power companies, oil and gas operators, water utilities, and renewable energy providers manage critical infrastructure that underpins society. Cybersecurity failures in this sector can have physical safety consequences.
Energy sector compliance is driven by critical infrastructure protection mandates. Regulators impose strict requirements on operational technology security, incident reporting, and supply chain risk management.
ETSI EN 303 645 provides 31 controls organised across 6 domains that can be mapped to energy-specific regulatory requirements. This structured approach helps organisations avoid compliance gaps while reducing the overhead of managing multiple overlapping obligations.
Energy Compliance Challenges
Energy organisations implementing ETSI EN 303 645 commonly face these challenges:
Protecting critical infrastructure from cyber-physical attacks
Meeting NERC CIP, IEC 62443, and national critical infrastructure requirements
Securing remote operational sites and legacy SCADA systems
Managing the cybersecurity implications of smart grid and IoT deployments
Balancing operational availability requirements with security patch management
Implementation Approach for Energy
1. Assess Current State
Conduct a readiness assessment against ETSI EN 303 645 to identify gaps specific to your energy environment. Our AI-powered assessment takes 5 minutes and produces a prioritised action plan.
2. Map Regulatory Overlap
Use cross-framework mapping to identify where ETSI EN 303 645 controls satisfy other energy regulations. This reduces duplicate effort and accelerates compliance.
3. Implement Priority Controls
Focus on high-risk gaps first, using energy-specific threat intelligence to prioritise controls that address your most material risks.
4. Monitor & Improve
Establish continuous monitoring and regular reassessment cycles. Energy regulations evolve frequently, so compliance is an ongoing programme, not a one-time project.
