UK7 - Contract Details Notice
Summary of the contracting process

Sheffield City Council procured DarkInvader, a cyber security service providing visibility of external cyber risk. The service is intended to help the council identify, prioritise and reduce risks arising outside its immediate network and to support compliance with the Cyber Assessment Framework (CAF) and Public Services Network (PSN) requirements. The requirement is classified as computer network services. Delivery is for Sheffield City Council in the United Kingdom. This is a service contract rather than a purchase of physical goods or construction works, and is relevant to providers of external attack-surface management, cyber risk monitoring, vulnerability prioritisation and related network security services for public sector organisations.

The procurement is complete and has been awarded to DarkInvader, an SME based in Leeds. Sheffield City Council used a direct award below the relevant threshold, without competition. The award was made on 29 May 2026, and the contract was signed on the same date. The contract runs from 18 June 2026 to 17 June 2027. Its value is £4,998 excluding VAT and £5,997.60 including VAT. There was one lot and one awarded supplier. The contract is active. The outcome indicates that the council selected a specialist provider for a defined cyber risk service through a below-threshold, non-competitive route.

This procurement demonstrates demand from Sheffield City Council for a focused external cyber risk capability rather than a broad technology implementation. Suppliers seeking comparable work would need a service that gives public sector security teams clear visibility of externally exposed assets and risks, supports prioritisation of remediation, and helps reduce those risks over time. Credibility would also depend on understanding the Cyber Assessment Framework and Public Services Network requirements, and on translating technical findings into evidence that a council can use for assurance and compliance. Relevant competitors are likely to include cyber security software providers, managed security specialists and network security consultancies able to deliver a repeatable service for a public authority at modest contract scale.
