COMPETITIVE EDGE

Holding DCC certification signals to the MOD and prime contractors that your security posture meets defence-grade standards — opening doors to contracts and frameworks that require supplier assurance.

What is Defence Cyber Certification?

BOOK A CALL

The Defence Cyber Certification (DCC) is the Ministry of Defence's new framework for supplier cyber assurance. Developed in partnership with IASME, it replaces the previous "per-contract" self-assessments with a robust, whole-organisation standard.

It assesses your entire organisation's ability to withstand cyber threats, covering not just IT systems but also Operational Technology (OT), physical security, and personnel.

Based on DEF STAN 05-138

Aligned with the latest UK defence standards for cybersecurity.

Requires Cyber Essentials

Builds upon the solid foundation of Cyber Essentials certification.
