Overview
Post Office Ltd (POL) is undertaking a multi-phase Identity & Access Management (IDAM) Transformation Programme, comprising multiple work packages across Customer CIAM, PAM/IGA, migration from legacy platforms, and Zero Trust alignment. The purpose of this Expression of Interest (EOI) is to: • support the discovery, validation, and mobilisation of the Identity & Access Management (IDAM) workstream under the Post Office Cyber Security Maturity Programme (CSMP) • Identify suppliers on TS3 Lots 1 and 2 with demonstrable capability to deliver outcome-based IDAM solutions. • Generate a shortlist (approx. 5-6 suppliers) to invite to the formal Initial Invitation to Tender (IIT). • Inform refinement of the IIT scope and procurement plan.
The total estimated value of this contract is between £4.5 million and £5 million over the full contract term. However, at the time of issuing this tender, only £800,000 has received formal funding approval.
The remaining contract value is subject to annual approval by POL's Board, and there is no guarantee that future funding will be secured. This funding dependency is disclosed as a known risk in accordance with the Procurement Act 2023.
