Challenge
The SaaS vendor's homegrown auth couldn't support enterprise SSO, granular roles, or the audit trails required by security-conscious buyers.
Solution
We built an identity API with OAuth2/OIDC flows, SAML SSO connectors, tenant-scoped RBAC, and immutable audit logs—documented with OpenAPI and SDKs for Node and Python.
