Defence Cyber Certification

Strengthening Cyber Resilience Across the Defence Supply Chain

From implementation to independent assessment, we support your DCC journey from first steps to full compliance.

What is the Defence Cyber Certification?

Defence Cyber Certification (DCC) is a UK Ministry of Defence standard designed to raise the bar on cyber maturity across the defence supply chain. It helps organisations demonstrate that they have the right systems, controls and processes to protect sensitive information and contribute to national cyber resilience. The framework aligns to Defence Standard (DEFSTAN) 05-138 and the NCSC’s Cyber Assessment Framework. There are four levels with varying levels of required controls:

  • Level 0: 3 controls
  • Level 1: 101 controls
  • Level 2: 139 controls
  • Level 3: 144 controls

Your required level is risk-related and will be detailed in your defence contract, or mandated by the MOD or a prime supplier. DCC is delivered on behalf of the MOD by IASME, and Protos Networks is a Level 1 DCC Certification Body (CB). We can support you whether you’re preparing for certification, implementing required controls, or seeking independent assessment. Many organisations choose to work with a CB in two ways: as an implementer (to help build and embed the right controls) or as an assessor (to independently verify compliance). Protos Networks is equipped to deliver a wide range of services across both paths, helping you meet DCC requirements with clarity and confidence.
