Strengthen Cyber Security Across the Defence Supply Chain
Securebytes provides support and guidance for organisations working towards IASME Defence Cyber Certification (DCC), helping businesses strengthen cyber resilience, improve security maturity, and demonstrate alignment with security expectations across the UK defence supply chain.
Defence Cyber Certification (DCC) is a cyber security certification framework developed by the UK Ministry of Defence (MOD) and IASME to help organisations protect sensitive information, strengthen operational security, and improve resilience against modern cyber threats.
The framework is designed for organisations operating within, or supporting, the defence sector and helps demonstrate that appropriate cyber security controls and governance processes are in place to protect systems, services, and sensitive defence-related information.
What Is Defence Cyber Certification (DCC)?
Defence Cyber Certification is a comprehensive cyber security framework designed to support improved security across organisations involved in defence-related supply chains and services.
The framework builds upon baseline security controls such as Cyber Essentials while introducing broader organisational, operational, and governance requirements designed to improve resilience against evolving cyber threats.
Areas commonly covered include:
- Security governance
- Risk management
- Access control
- Asset management
- Incident response
- Security monitoring
- Vulnerability management
- Supply chain security
- Data protection and handling
- Operational security processes
DCC helps organisations demonstrate a more mature and structured approach to cyber security management.
Defence Cyber Certification Levels
Defence Cyber Certification (DCC) is structured across four certification levels designed to align security requirements with the sensitivity and risk associated with defence-related contracts and information handling.
Level 0
Level 0 is designed for organisations that do not process, store, or access sensitive defence-related information but still require a baseline understanding of cyber security responsibilities within the defence supply chain.
Level 1
Level 1 aligns closely with Cyber Essentials requirements and focuses on establishing fundamental technical cyber security controls designed to protect against common internet-based threats.
This level is suitable for organisations handling lower-risk defence-related information and services.
Level 2
Level 2 introduces broader governance, operational, and organisational security requirements beyond baseline technical controls alone. This includes areas such as risk management, incident response, access control, and security processes.
This level is intended for organisations supporting higher-risk defence contracts or handling more sensitive information.
Level 3
Level 3 represents the most comprehensive level of Defence Cyber Certification and is designed for organisations operating within higher-risk defence environments where strong cyber resilience, governance, and operational security controls are critical.
Requirements at this level focus on mature security management practices, enhanced resilience, and ongoing security improvement.
Why Achieve Defence Cyber Certification?
Defence Cyber Certification helps organisations:
- Demonstrate cyber security maturity
- Strengthen resilience against cyber threats
- Support defence sector supply chain requirements
- Improve governance and operational security
- Build trust with customers and stakeholders
- Reduce exposure to security risks
- Support contractual and assurance requirements
For organisations operating within defence-related supply chains, DCC can help demonstrate commitment to protecting sensitive information and maintaining strong security standards.
