The Situation

The state government required an urgent migration from a legacy, bespoke CIAM platform to support a departmental transition. The timeline was non-negotiable: the new capability had to be delivered within a fixed government deadline. The solution needed to support a closed community model (where only invited organisations could participate), self-service access management for external organisations, and seamless integration with existing government identity services.

What We Did

CIAM Platform Delivery

Modern 42 partnered with the ICT services provider to design, build and deploy the new CIAM capability on Microsoft Entra External ID, with Apporetum delivering delegated access management. The solution included out-of-the-box Sign Up and Sign In flows configured to meet the business requirements, bespoke web application development to support the closed community requirement, delegated access management via Apporetum deployed from the Microsoft Marketplace, B2B capability allowing business owners to seamlessly interact with reliant applications, and full service design covering processes, accountabilities and documentation for external customers, business owners and technical operators.

The Outcome

The organisation successfully migrated off the legacy CIAM channel to the new Entra External ID solution within the required deadline. The solution integrated tightly with other identity services and transitioned seamlessly to the BAU team for ongoing operations and maintenance.
