Blog post from WorkOS
Enterprise Single Sign-On (SSO) is essential for B2B SaaS companies to secure significant contracts and meet IT team requirements, making the choice of SSO platform crucial due to the potential long-term integration and migration implications. A comprehensive guide evaluates seven leading SSO providers for B2B SaaS teams in 2026, each suited to different needs. WorkOS is tailored for fast enterprise deals with pre-built integrations and a self-serve admin portal, while Auth0 offers a wide feature set for teams with complex identity needs, though it requires significant engineering effort for customization. Clerk, focusing on speed for React and Next.js teams, is expanding its enterprise features but may need future migration, whereas Okta provides extensive capabilities for large enterprises but can be overwhelming for smaller teams. Microsoft Entra ID integrates well with Azure but lacks specific B2B SaaS tooling, and Ping Identity caters to regulated industries needing deployment flexibility. Keycloak offers open-source control but demands significant engineering resources for maintenance. The guide emphasizes that choosing a platform designed for enterprise use from the start can prevent growth disruptions and save engineering resources in the long run.
