Defence Cyber Certification (DCC)
In the UK’s defence sector, the landscape of procurement is changing. With the full implementation of the Ministry of Defence (MOD) Cyber Security Model (CSM) v4 and DEFCON 658, demonstrating your security posture is no longer optional. For many SMEs and new suppliers, Defence Cyber Certification (DCC) Level 0 is the critical first step to staying “tender-ready.”
At Vincent Cyber Defence, we are an approved IASME Certification Body specifically trained to guide you through the DCC framework. We provide the “full package”, combining your mandatory Cyber Essentials with the specific DCC Level 0 controls, ensuring a seamless, jargon-free path to compliance.
The Benefits of DCC Level 0 for Defence Suppliers
Unlock New MOD & Prime Contractor Opportunities
DCC Level 0 is designed for contracts with a “Very Low” cyber risk profile. As the MOD phases out individual Supplier Assurance Questionnaires (SAQs) in favour of this single, organisation-wide certification, holding a DCC certificate makes you an “oven-ready” partner for Primes and the MOD alike. It is your formal “license to operate” in the defence market.
Streamline Your Procurement Compliance
Rather than completing complex, repetitive assessments for every single contract, DCC Level 0 provides a verified status that lasts for three years (subject to annual attestation). We help you map your existing security to Defence Standard 05-138 Issue 4, reducing the administrative burden on your team and allowing you to focus on delivery.
Strengthen Foundational Resilience
Level 0 goes beyond basic IT to focus on the resilience of your entire business. By validating your approach to UK GDPR, Data Security Basics, and Network Resilience, we ensure your business isn’t just compliant on paper, but genuinely protected against the disruptions that target the defence supply chain.
A Cost-Effective, “No-Fuss” Solution for SMEs
We understand that smaller suppliers don’t need the overhead of high-level military encryption. Level 0 is the accessible, proportionate entry point. Our assessors work with you in plain English to verify the three core DCC controls alongside your Cyber Essentials, providing expert UK-based support that fits your budget.
Frequently Asked Questions for DCC Level 0
What is the difference between Cyber Essentials and DCC Level 0?
Cyber Essentials is the technical prerequisite, it secures your IT infrastructure. DCC Level 0 is the defence-specific layer on top. It requires a valid Cyber Essentials certificate plus evidence of three specific areas: UK GDPR compliance, data security fundamentals, and system resilience. You need both to meet the 2026 MOD requirements.
Is DCC Level 0 mandatory for all defence work?
Under CSM v4, the MOD and Prime contractors determine the “Cyber Risk Profile” (CRP) for every contract. If your contract is graded as “Level 0” or “Very Low Risk,” you will be expected to hold this certification. It is rapidly becoming the standard expectation for all sub-contractors in the UK defence supply chain.
How long does the DCC Level 0 certification last?
The DCC certificate is valid for three years. However, you must maintain your annual Cyber Essentials certification and provide a simple annual attestation to IASME to confirm your security scope hasn’t changed.
Can Vincent Cyber Defence handle both my Cyber Essentials and DCC?
Yes. As a dedicated IASME Certification Body, we offer the full package. We can align your Cyber Essentials assessment with your DCC Level 0 requirements, ensuring you don’t repeat work and that your evidence is consistent across both frameworks.
