OIDC vs SAML in Hybrid Cloud: When to Use Each Protocol

The Flexera 2025 State of the Cloud Report highlights that 70% of organizations are employing a hybrid cloud strategy, balancing between public and private clouds, which necessitates a dual approach to authentication protocols using both SAML and OpenID Connect (OIDC). SAML, ratified in 2005, is suited for traditional enterprise web applications with XML assertions, while OIDC, finalized in 2014, is better for modern cloud, mobile, and API workloads with compact JSON Web Tokens (JWTs). In a hybrid environment, the choice of protocol is tied to the service provider's native support, requiring organizations to often use both SAML for legacy systems and OIDC for newer applications, and manage user provisioning separately through SCIM 2.0. The decision isn't about replacing one protocol with another but rather integrating them to fit respective system requirements, with tools like SSOJet helping normalize the differences by allowing seamless connections across various identity providers. This coexistence is crucial as it ensures secure, efficient authentication processes while maintaining flexibility across diverse technological landscapes.
