Questions asked by suppliers

1. Can you provide more clarity into the levels of security clearance levels that may be required?
It is the intention that the HO will purchase an existing capability for Web Image Metadata Matching. Use of an existing capability will not require any specific security clearance by the supplier. If, however, during the term of the contract the supplier is required to have detailed knowledge about the CAID system architecture, any staff involved will be required to comply with the Baseline Personnel Security Standard (BPSS). They may also be required to obtain Non-Police Personnel Vetting Level 2 (NPPV2)
