Challenge

Identity Sprawl: More Risk, More Rigidity, Less Control

Enterprises today often operate without a single source of truth, creating a fragmented identity ecosystem. You're juggling Azure Entra ID, Auth0, Okta, Ping, legacy identity providers, and on-prem Active Directory/Lightweight Directory Access Protocol, compounded by mergers and acquisitions and partner demands to "use our IdP." Each new integration adds complexity, results in inconsistent policies, and mounting operational risk.

Impact of Doing Nothing

Leads to Fragmentation, Vulnerability, and Friction

This fragmented landscape forces manual configuration, protocol juggling, and time-draining mappings for every new identity provider or partner. Developers are forced to hard-code trust logic into applications, creating security inconsistencies and slowing delivery. The net result is a fragile patchwork of integrations, compliance gaps, and a disjointed user experience.
