A few multi-tenant authentication platforms that support both OIDC and SAML for enterprise SaaS customers are:
- Auth0 (by Okta) — strong enterprise B2B features, supports OIDC and SAML connections, organizations/tenancy patterns.
- WorkOS — built specifically for SaaS B2B enterprise auth; supports SSO via SAML and OIDC, plus SCIM and directory sync.
- Okta Customer Identity / CIAM — supports both protocols and enterprise federation use cases.
- Ping Identity / PingOne for Customers — supports OIDC and SAML with enterprise federation.
- Microsoft Entra External ID — supports modern auth and enterprise federation scenarios, including OIDC and SAML integrations.
If you want the best fit for multi-tenant SaaS with enterprise SSO, WorkOS and Auth0 are the most common picks.
If you want, I can also compare them by:
- ease of multi-tenant setup
- pricing
- SCIM support
- white-labeling
- developer experience
