How it works

How your DCC level is decided.

DCC has four levels under DefStan 05-138. The level you need is the Cyber Risk Profile a buyer assigns to a specific contract through a cyber risk assessment of the work. Suppliers do not choose the level a contract requires, though you can choose to certify at or above it to win future work.

Level 0 · Basic

Very low assessed risk

The entry level. Three controls: Cyber Essentials as the pre-objective, UK GDPR compliance, and resilient networks and systems.

Level 1 · Foundational

Low to moderate assessed risk

101 controls under DefStan 05-138, building on the Level 0 baseline into a comprehensive cyber security programme.

Level 2 · Advanced

High assessed risk

139 controls. Adds Cyber Essentials Plus and advanced cyber security oversight on top of Level 1.

Level 3 · Expert

Substantial assessed risk

144 controls, the highest level. Adds Cyber Essentials Plus and a full defence-in-depth approach.

FAQ

DCC eligibility, answered

The questions suppliers ask before they start.

Who needs DCC certification?

Suppliers working with the UK Ministry of Defence, either directly or as a subcontractor to a defence prime, need Defence Cyber Certification when a contract requires it. DCC is being cited in defence contracts under DefStan 05-138, and primes flow the requirement down to their supply chain. If you do not work with the MOD or its primes, you do not currently need DCC.

How is our DCC level decided?

Your DCC level is the Cyber Risk Profile the buyer assigns to a specific contract, through the Cyber Security Model risk assessment process under DefStan 05-138. It reflects the assessed cyber risk of the work, judged at a whole-organisation level rather than by information sensitivity alone. Suppliers do not choose the level a contract requires, though you can choose to certify at or above it. This assessment estimates the level you should expect, but you must confirm the required level against your contract.

Can we choose our own DCC level?

No. The DCC level you need is determined by the contract, not by the supplier. The MOD or the prime contractor assesses the cyber risk of the work and assigns a level. You cannot opt for a lower level than the one your contract requires, although holding a higher certification than required is acceptable.

What are the DCC certification levels?

DCC has four levels under DefStan 05-138, from Level 0 to Level 3. Level 0 is the entry level for suppliers with a very low assessed cyber risk. Levels 1, 2 and 3 apply to progressively higher assessed risk, with more controls and, from Level 2 upward, a requirement for Cyber Essentials Plus. Snubnose supports certification at all four levels.

Do we need Cyber Essentials before DCC?

Cyber Essentials is the pre-objective for DCC Level 0 and a prerequisite at every DCC level. Cyber Essentials covers Levels 0 and 1; Cyber Essentials Plus is required for Levels 2 and 3. If you already hold Cyber Essentials, you are part of the way through DCC Level 0 before you start.

Is this assessment a binding determination of our DCC level?

No. The result is indicative only. The binding level is the Cyber Risk Profile the buyer flows down on a specific contract under DefStan 05-138. Use this assessment to plan ahead, then confirm the required level against your contract or with your prime contractor.
