Defence Cyber Protection Partnership

Defence Cyber Protection Partnership (DCPP) is a joint Ministry of Defence (MOD) and industry initiative to improve the protection of the defence supply chain from the cyber threat.

Interim process for new contracts

MOD Risk Assessment (RA)

The MOD Project/Delivery Manager needs to complete the Risk Assessment (RA) via the interim process. Please request forms via email to the DCPP Team: Please return forms as Microsoft (preferred) or convert to PDF.

Supplier Assurance Questionnaire (SAQ)

Tenderers must still complete an SAQ to be provided with tender responses. The MOD Project Team will provide the SAQ. On completion, this must be sent to the DCPP Team for a result to be provided. The completed SAQ and result must be included with tender responses, along with a Cyber Implementation Plan (CIP) if appropriate.

Flow down

Whilst the interim process is in place, flow down of the Risk Assessment/Supplier Assurance Questionnaire process to sub-contracts will be required for contracts with a high-risk profile only. All other levels must be completed during a grace period after the new tool goes live.


DEFCON 658 will continue to be included in contracts. Cyber Implementation Plans (CIPs) will continue to be needed as usual where SAQs indicate non-compliance (for all Tier 1 SAQs and High flow down).

Thank you for your patience.

Understanding more about the Cyber Security Model

Watch a video explaining the Cyber Security Model

The Cyber Risk Profile is assessed on 6 questions relating to:

Cyber Essentials underpins the MOD Cyber Risk Profiles. Cyber Essentials is a certification scheme identifying the minimum steps an organisation should take to protect themselves against cyber risk.

The Supplier Assurance Questionnaire is a self-assessment for organisations to demonstrate how they meet our requirements. The online tool allows sample questionnaires to be completed to identify gaps. Where there are differences a Cyber Implementation Plan (CIP) should be completed, particularly if an alternative cyber security standard is used.

Further information on CIPs can be found in:
