What is Defence Cyber Certification (DCC)?
Defence Cyber Certification (DCC) is a formal, organisation-wide cyber security certification for businesses working in or supplying the defence sector. It was created by the Ministry of Defence (MoD) and IASME.
The DCC scheme sets our cyber security requirements for MoD suppliers, defined in Defence Standard (DEFSTAN) 05-138. If a contract requires DCC, you must hold the relevant certification level before you can bid for it.
DCC replaces the previous Supplier Assurance Questionnaire (SAQ), with formal, third-party verified certification. That gives defence buyers trusted assurance that your cyber security meets the standard the contract requires.
Certification is valid for three years, with annual attestation to confirm you still meet the requirements.

Defence Cyber Certification levels
There are four DCC levels. The level you need depends on the cyber risk profile assigned to the contract you want to bid for.

Which DCC level does your business need?
Every MoD contract is given a cyber risk profile, based on the four levels in Defence Standard 05-138. The level on your contract sets the minimum certification you need before you can bid. If you’re not sure which level you need, we’ll help you work it out.

What are the benefits of Defence Cyber Certification?
DCC can feel like a lot to take on, especially if it’s new for you. Here’s what you get when you work with us:

Bid for MoD contracts
Some MoD contracts require DCC. Without the right level of certification, you can’t bid. With it, you can.

Prove your cyber resilience
DCC shows defence buyers you’ve had your cyber security independently assessed and verified.

Strengthen your credibility
Prime contractors and buyers want assurance from their suppliers. DCC certification gives them that.

Protect sensitive data
Defence suppliers handle sensitive information. The DCC process identifies gaps in your security controls and gives you a clear path to close them.
Frequently Asked Questions
The level you need is determined by the cyber risk profile assigned to the MoD contract you want to bid for. If the contract is assessed at Level 1, you need DCC Level 1 certification as a minimum. If you’re unsure what level applies to your situation, speak to one of our consultants and we’ll help you work it out before you start the process.
DCC is for any business that supplies, or wants to supply, the Ministry of Defence. That includes businesses at any tier of the defence supply chain, not just prime contractors. If you’re bidding for an MoD contract that carries a DCC requirement, it applies to you.
DCC is mandatory for MoD contracts that carry a DCC requirement. If the contract specifies a DCC level, you must hold that certification before you can bid. Not all MoD contracts require DCC, the requirement depends on the cyber risk profile of the specific contract.
The MoD introduced DCC to raise and standardise cyber security across its supply chain. Previous self-assessment routes, including the Supplier Assurance Questionnaire, didn’t provide buyers with independently verified assurance of a supplier’s cyber resilience. DCC replaces them with formal certification to give the MoD and prime contractors a consistent, trusted standard to work to.
The time it takes depends on your DCC level, how complex your organisation is, and how ready your cyber security controls are when you start. At Level 0, the process is relatively straightforward. Level 1 involves 101 controls and a gap analysis, so typically takes longer. We’ll give you a realistic picture of the timeline during your initial assessment preparation.
Yes. Both DCC Level 0 and DCC Level 1 require Cyber Essentials certification. If you don’t already hold it, you’ll need to achieve it as part of your DCC process. Citation Cyber is an established Cyber Essentials certifier, so we can support both certifications together.
The Supplier Assurance Questionnaire (SAQ) was a previous self-assessment tool used by MoD suppliers to demonstrate their cyber security posture. It has been replaced by DCC, which requires formal third-party certification rather than self-declaration. If you’ve previously completed an SAQ, you’ll need to move to DCC to continue bidding for contracts that carry a cyber security requirement.
