Award Notice
Summary of the contracting process

The Home Office procured specialist red teaming services for its Science and Technology unit. The work involves independent, adversary-simulated assessments of selected sites and systems, testing physical and digital security controls and identifying vulnerabilities. This is a security testing and assurance service, with a research and development classification (CPV 73300000). Delivery may be required in the United Kingdom, British Overseas Territories, the Channel Islands, the Isle of Man, elsewhere in Europe and the rest of the world. The requirement is for service providers able to assess both physical security arrangements and digital systems, and to provide independent findings that help the Home Office understand and address weaknesses.

The procurement has been awarded following a selective call-off from a dynamic purchasing system. Bids had to be submitted by 2 July 2026 at 12:00. The contract was awarded to Cerastes Limited on 30 July 2026 for £1,500,000 including the stated contract value, covering the period from 7 August 2026 to 6 August 2029. The award is active and the tender is complete. The requirement was identified as suitable for small and medium-sized enterprises. The award was made for specialist red teaming services as a single requirement, with the work covering physical and digital security assessments across the stated delivery locations.

This award demonstrates demand from the Home Office for independent red teaming that combines physical security testing with digital security assessment. Suppliers seeking to compete for comparable work should be able to simulate credible adversary activity, assess sites and systems in multiple operating environments, identify vulnerabilities and present findings that can support practical improvements to security controls. The selected supplier profile indicates that an SME can deliver the requirement, so relevant specialist firms do not necessarily need the scale of a large national contractor. Credibility will depend on demonstrable capability across both physical and cyber security, independence of assessment, disciplined vulnerability analysis and the capacity to work across varied locations.
