Zero-trust auth system
A financial services firm consolidated identity management across three internal platforms into a single zero-trust auth layer. Independent user databases, inconsistent session handling, and no central revocation were flagged as critical control failures by external compliance auditors.

Three applications maintained separate user stores and session tokens with no shared revocation capability. Revoking a compromised account required manual action in three systems — taking up to 30 minutes. Audit logs were fragmented across platforms, making compliance reporting a multi-day effort.

We deployed Keycloak as the central IdP with OAuth 2.0 Authorization Code + PKCE flows and OIDC discovery endpoints. Each platform was integrated via confidential clients with short-lived JWTs (15-min TTL) and refresh token rotation. RBAC roles were mapped from Active Directory group membership, enabling fine-grained permissions without application-level user management. A single audit stream now captures all authentication events across all three platforms.

Revoking user access across all systems now takes under 5 seconds via a single admin action. The firm passed an external penetration test with zero critical findings and satisfied all compliance audit requirements. Compliance reporting that previously took days is now automated.
