ICS and OT CybersecurityUK Energy Sector

Harden industrial control systems on live UK energy infrastructure without disrupting operations.

We place OT security specialists who can secure the industrial control systems behind UK energy generation and distribution — hardening live environments, building visibility into industrial network traffic, and meeting tightening compliance requirements without taking grid operations offline.

Our Approach

OT security is a different discipline from IT security.

OT environments have different protocols, different operational constraints, and different consequences when something goes wrong. We place OT security specialists with energy sector experience — not IT security professionals repackaged for industrial environments.

OT-specific. Energy-sector experienced. Compliance-ready.

The Compliance Landscape

The compliance landscape is tightening.

The requirements are tightening across NIS2, IEC 62443, Ofgem and NERC CIP — and most OT environments are not keeping pace.

  • NIS2 & UK NIS

    Controls, reporting, supply chain

  • IEC 62443

    Industrial cybersecurity standard

  • Ofgem

    Sector cybersecurity requirements

  • NERC CIP

    Interconnector & generation

Our Capabilities

What we deliver on your programme.

Seven capabilities spanning assessment, monitoring, compliance and incident response — each designed around the operational uptime requirements of live grid infrastructure.

Capability 03

Compliance, incident response and supply chain.

Regulatory compliance and audit readiness
Documentation, controls and audit trails for NIS2, IEC 62443 and Ofgem cybersecurity compliance.
Incident response planning and exercising
OT-specific incident response plans and tabletop exercises for environments where security events affect live grid infrastructure.
Supply chain security
Vendor security assessments and contractual security requirements for OT supply chains.
Challenges We Solve

The problems we hear most often from delivery teams.

Recurring OT security gaps on UK energy programmes — and the specialists we place to close them.

01

Meet NIS2 and IEC 62443 compliance requirements

Our specialists build the documentation, controls and audit trails needed for NIS2 and IEC 62443 compliance in OT environments.

02

Secure OT without disrupting live operations

Hardening industrial control systems has to be done without disrupting live grid operations.

03

Get visibility into OT network traffic

Most OT environments have limited visibility into industrial network activity. We deploy OT-native monitoring tools to provide that visibility.

04

Assess and manage supply chain risk

NIS2 and Ofgem requirements extend to supply chain security. We assess vendor security posture and build contractual security requirements into procurement.

05

Plan and exercise for OT security incidents

OT incident response is different from IT incident response. The consequences extend to live grid operations.

FAQ

Frequently asked questions

  • IT security focuses on protecting data and enterprise systems. OT security focuses on protecting hardware and software that controls physical processes. In an OT environment, operational continuity takes precedence over security controls that would be standard in IT.
