Seamless SAML 2.0 Federation for Enterprise SSO

Integrate with public sector systems, legacy applications, and enterprise IdPs through full support for SAML 2.0—the most widely adopted federation protocol.

Enterprise SSO with Proven SAML 2.0 Compatibility

Why It Matters

SAML 2.0 is the most widely adopted standard for cross-domain Single Sign-On (SSO) in large organizations, especially public institutions, financial systems, and enterprise software. Keycloak—and by extension, Keymate—offers robust, production-grade support for the full SAML 2.0 specification. This includes bindings like HTTP-Redirect, HTTP-POST, and Artifact; features like metadata import/export, encryption/signing, and Single Logout (SLO). Legacy SAML 1.1 is no longer supported, in alignment with modern security and federation standards.

Federated Login Flow with Keycloak as IdP

Service Provider sends an AuthnRequest (via redirect or POST). Keycloak validates the user and generates a signed SAML Assertion. Assertion is posted or redirected back to the SP. SP validates the assertion and starts the local session. SLO (Single Logout) optionally propagates logout events to other SPs.

Yes—especially in public sector and enterprise IT. It's still the dominant standard for federated SSO.

No. Keycloak only supports SAML 2.0, which is the latest version of the specification.

Yes. Single Logout is fully supported via NameID propagation and session synchronization.

Absolutely. Keycloak allows hybrid federation models with SAML, OIDC, and even legacy IdPs.
