OIDC vs SAML for Enterprise SSO: A 2026 Decision Guide - Part 3
Blog post from Clerk
This part of the four-part series on choosing between OIDC and SAML for enterprise SSO in 2026 provides a comprehensive decision guide, emphasizing the importance of completing a risk assessment framework that considers compliance risks, provider availability, and a risk-scoring matrix across five dimensions: protocol attack surface, configuration risk, provider disclosure quality, reliability, and compliance fit. The guide suggests that enterprises should support both SAML and OIDC to accommodate diverse customer requirements, as different industries and customers have varying needs that might require one protocol or the other. It highlights that the choice of protocol should not be the initial focus; instead, organizations should first consider their customers' IdP landscape, compliance needs, and whether they are building or buying their SSO solution. The text also covers the importance of SCIM provisioning for compliance and operational efficiency and notes that a provider supporting both protocols can offer a more predictable pricing model based on enterprise connections rather than the number of users. It concludes by stressing the benefits of a dual-protocol support strategy, which can streamline sales processes and ensure compatibility with a broad range of customer demands.
