What is Defence Cyber Certification?
The Defence Cyber Certification (DCC) is a comprehensive, cyber security certification framework for UK defence suppliers. Developed by the UK Ministry of Defence (MOD) and IASME, the certification is part of the broader initiative to enhance the cyber resilience of the UK’s defence sector supply chain.
The DCC certification emphasises the overall security and resilience of the organisation. It provides a single, organisation-level, assurance which can be presented in support of UK Defence Procurements (subject to annual attestation and re-certification every three years).
Successfully obtaining and maintaining certification under the DCC scheme is a clear demonstration of an organisation’s ongoing commitment to cyber resilience in support of continued improvement to cyber resilience in UK Defence.
