Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, with reference to the Answer of 17 November 2025 to Question 88027 on NHS: Databases, what logging systems are used to record and review access to identifiable patient data within the National Data Integration Tenant.

The National Data Integration Tenant operates within a secure environment with strict controls governing access to data.

All access to data within the system is logged and auditable. Comprehensive audit trails are maintained which record user activity, including access to identifiable patient data, and enable monitoring and review of system use.

The Foundry platform has comprehensive auditing capabilities as detailed at the following link:

In addition, the audit logs are integrated with the National Cyber Security Centre’s Security Information and Event Management capability.
