Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, pursuant to the Answer of 3 September 2025 to Question 72570 on National Security: Infrastructure, when he plans to have completed delivery of CNI Knowledge Base.

The CNI Knowledge Base is a secure digital tool that is designed to be a “single source of truth for UK CNI’’. CNI Knowledge Base is part of the National Situation Centre.

The CNI Knowledge Base’s roll-out across the government is complete. The Knowledge Base maps both physical and logical CNI systems and the supporting systems which keep them running. This enables government to identify linkages and dependencies between systems and across CNI sectors. Departments are already using it to understand key CNI systems and the potential impacts of hazards, threats and risks. We are continually introducing new features and onboarding more users.
