National Cyber Security Governance & Energy CNI | Case Study

National

Government IT estate under SIRO accountability

SIRO

Government accountability with CNI oversight

Zero

Major nonconformities at ISO 27001 Stage 2

Energy CNI

Utility SIRO reporting into the national structure

The opportunity

No national capability, no coordinated governance

No national cyber capability existed.
No coordinated governance across government and critical national infrastructure.
No NCSC relationship, with utilities operating independently and at inconsistent levels of security maturity.

What we delivered

Building the institution, then the assurance

Created a jurisdiction’s first national cyber body, from a standing start.
Authored the national cyber security strategy, adopted at ministerial level.
Established an operational relationship with the NCSC: threat intelligence, bulletins and incident reporting.
Applied CAF methodology to assess cyber security risk, implement repeatable processes, and used the maturity sourcing model to assess improvements delivered through the remediation programme.
Built a jurisdiction-wide SIRO network spanning central government and critical national infrastructure.
Held government SIRO accountability, with the energy utility SIRO reporting into the national structure.
Mentored the energy utility SIRO and supported ISMS implementation.
Drove central government to ISO 27001 certification with zero major nonconformities.

The outcome

A repeatable model for CNI governance

Unified governance across government and critical national infrastructure.
Energy utility brought within national security oversight.
A repeatable model for CNI governance established.
ISO 27001 certified, securing regulator confidence.
