From Federation Sprawl to Unified Identity: How to Make Verified Identity Reusable Across Systems

Identity fragmentation isn’t usually the result of bad architecture. It’s the natural byproduct of growth. New apps get added. Business units operate independently. Acquisitions bring in new identity stacks. And over time, even well-designed IAM environments start to sprawl.

In our recent masterclass, Richard Esplin (Head of Product) and Agne Caunt (Product Owner) walked through what this looks like in the real world and, more importantly, how organizations can evolve toward a unified identity architecture without ripping out the systems they already rely on. The session explored the limits of traditional federation, the shift toward reusable digital ID credentials, and a practical, phased path teams can use to reduce duplication, improve flexibility, and move closer to a zero trust model.
