The Cabinet Office supports the Prime Minister and ensures the smooth running of government, from developing policy, to modernising public services. Within the Cabinet Office, the Security & Resilience (COSR) Team is the lead body for managing protective security, advising business units, and mitigating security threats across the department.

- STRAP Team (STRAPSO): Regulates and monitors access to highly sensitive intelligence material that requires specialised protective handling beyond standard government arrangements.
- Incident Management Team: Managing security incidents, assessing risks, analysing data and where necessary, escalating incidents and emerging threats to the correct team or stakeholder.
As a security Support Officer, your duties will include:
- Managing team inboxes, operational tracking systems, and taking on-call or out-of-hours responsibilities as required.
- Administering National Security Vetting (NSV) applications, transfers, and clearance processes, ensuring accuracy and complete records.
- Verifying candidate and stakeholder information to maintain the integrity of vetting databases, as well as managing the vetting aftercare and leavers’ processes.
