The Project

Cyber GSeC has developed a pilot proposition covering supplier security assurance. The aim of this pilot is to assess the feasibility of collating and storing supplier security assurance (cyber and protective) information in a central repository, which can then be accessed and shared across government to support efforts to manage and reduce several risks within HMG.

The pilot has the following objectives

  • to establish a centralised repository of high-level information and evidence about a supplier’s security assurance status including their subcontractor position, against a baseline security assurance criteria. This information can be utilised by other government departments to save time and resource when they undertake their own due diligence.

  • to help government to understand and reduce its supply chain risk.
