From Access to Readiness: Supporting Suppliers in a Stronger Defence Supply Chain
Why Defence Cyber Certification should be on every supplier’s radar
In May, Eleanor Fairford, Director of Cyber Defence and Risk at the Ministry of Defence, confirmed that industry partners have been asked to achieve Level 0 Defence Cyber Certification by 31 December 2026 (Gov UK, 2026).
For suppliers working in, or looking to enter, UK defence and secure government markets, this is an important signal. Cyber resilience is now an essential part of supplier readiness across UK defence and secure government markets. As the Ministry of Defence (MOD) continues to strengthen assurance and develop clearer expectations across the defence supply chain, Defence Cyber Certification (DCC) gives suppliers a practical way to demonstrate that they understand what is expected, are taking the right steps, and can evidence good cyber security practice at an appropriate level.
MOD is also increasing its engagement with SMEs, specialist providers and non-traditional suppliers. Through the Neutral Vendor Framework for Innovation (NVfI), that shift is already being seen and proven, with 88% of contracts awarded to SMEs to date.
As more suppliers engage with MOD and public sector buyers operating in secure environments through collaborative and compliant routes, cyber assurance becomes part of being ready to act on those opportunities.
For suppliers, this raises a useful question: if access to defence is improving, how can organisations ensure they are ready for the assurance expectations that come with it?
The opportunity is to make the journey clearer by helping suppliers understand DCC, prepare at the right level and access the guidance and support they need to move forward with confidence.
What is Defence Cyber Certification?
DCC is an organisation-wide cyber security certification framework for UK defence suppliers. Developed by the MOD and delivered with IASME, it is designed to improve the cyber security position of the UK defence supply chain and provide trusted assurance that a supplier’s cyber resilience has been assessed against an appropriate standard.
The framework is available across four levels: Level 0, 1, 2 and 3. This progressive structure means organisations can certify at a level that reflects their risk, maturity and role within the defence supply chain, then build on that assurance as their involvement in defence work evolves. Organisations will undergo recertification every three years to ensure assurance remains current over time.
From access to readiness
A stronger defence supply chain depends on suppliers of all sizes meeting appropriate standards. SMEs, niche providers and non-traditional suppliers play a vital role in bringing innovation, specialist expertise and responsive capability into defence and secure government markets.
DCC gives suppliers a structured way to demonstrate cyber resilience, while giving buyers greater confidence across a broader and more diverse supplier base. The question for suppliers is not only whether their capability is relevant to defence, but whether they can evidence the readiness buyers may expect.
Why Level 0 should be on suppliers’ radar
Level 0 is the immediate starting point for many suppliers. It gives organisations a clear baseline for understanding what good cyber security practice looks like in a defence context and provides a practical first step towards demonstrating readiness.
For suppliers, the priority is not to wait until certification becomes part of a live opportunity. A useful first step is to understand what Level 0 means in practice, how it relates to current or future defence work, and what evidence may need to be gathered.
Why should suppliers be asking themselves now?
Particularly for smaller suppliers who may not have dedicated cyber or compliance teams, breaking the process down into practical questions can help suppliers understand what DCC may mean for their organisation.
How practical support can help
Access to opportunities is only part of supplier readiness. Clear guidance, practical education and the right partner connections can help suppliers understand what DCC means for their organisation and what steps may be needed next.
At Constellia, we are certified to Defence Cyber Certification Level 1. This gives us direct experience of what certification involves and why it matters. For buyers, certification provides benchmarked assurance that a supplier has met requirements appropriate to the risks associated with their work. For suppliers, it is a clear way to demonstrate an ongoing commitment to cyber resilience and readiness.
As an SME ourselves, Constellia understands that smaller teams do not always have the same time, budget, or support when navigating public sector processes. Our role is to help suppliers understand DCC, access the right guidance, and connect with approved partners who can support them in becoming DCC-ready.
This can include education on DCC, practical guidance and introductions to approved partners where specialist support is needed.
Taking the next step
For suppliers working in, or looking to enter, UK defence and secure government sectors, now is the right time to understand what DCC means for your organisation, consider what Level 0 may involve, and prepare with the right guidance around you.
