Assurance for energy, utilities and critical infrastructure
Resilience for the systems society depends on.
Energy and utility operators run safety- and society-critical systems where a cyber failure can have physical consequences. We assess OT/ICS security, critical-asset protection and resilience using a safe methodology — aligned to IEC 62443 and continuity good practice.
Business context
Energy, water and utility operators depend on industrial control systems and complex IT/OT interdependencies. Many are designated critical-infrastructure operators with jurisdiction-specific obligations, so assurance must combine OT expertise with precise applicability scoping.
Major cyber & governance challenges
What the sector is up against.
OT/ICS cybersecurity
Industrial control systems with legacy technology and long lifecycles.
Critical-asset protection
Failure can affect safety and essential services.
IT/OT interdependencies
Physical and cyber dependencies that must be understood together.
Supply-chain security
Equipment and integrator risk across the value chain.
Continuity & recovery
Resilience and recovery of essential services is paramount.
Relevant regulatory landscape
What may apply — and to whom.
IEC 62443 series
Details →The reference standard for industrial control-system security.
NIST SP 800-82
US guidance for OT/ICS security (reference).
ISO 22301
Details →Business-continuity management baseline.
Critical-infrastructure requirements
Details →Where designated (jurisdiction-specific).
Applicability is organisation-specific. This is general information, not a legal determination — we confirm what applies to you during scoping. See the Framework Library for sources and classifications.
