A Government Arm’s-Length Body required a significant uplift in its cyber security posture, starting from a low maturity baseline and with limited organisation-wide awareness of risk.
HM3 collaborated closely with the CISO to define a clear cyber vision, capture key business drivers, and secure board-level buy-in.
We developed and gained approval for the business case, then built out the entire improvement portfolio, including:
PMO, SOC, and IAM functions
Target Operating Model & ISMS
DevSecOps and GRC capabilities
End-user Education & Awareness programme
We also established a robust governance regime to measure risk, track progress, and drive delivery.
