Modernising enterprise authorisation at scale

Assignment context: American Express

The challenge

Enterprise access is deeply embedded in applications and operating processes. Replacing the underlying identity system therefore meant more than building a new service: applications, data and users all needed a safe transition path.

The approach

The assignment covered architecture, design and delivery of a policy-based authorisation platform. A multi-year roadmap broke the transition into measurable stages. Migration and onboarding were sequenced according to risk, with engineering, security, operations and business stakeholders involved throughout.

The value demonstrated

This experience shows how bitswiz.tech approaches modernisation when continuity and security matter as much as the target architecture: make the dependencies visible, reduce transition risk and carry the design through to production.
