Blog post from Clerk
In the second part of a three-part comparison between Clerk and Auth0, the focus is on enterprise capabilities, including B2B support, SSO, SCIM provisioning, RBAC, and security. Both platforms offer robust B2B features, but differ in approach: Clerk provides prebuilt UI components and bundled features, while Auth0 requires configuration and separate enablement steps. Both support SAML and OIDC for enterprise SSO and SCIM provisioning, with updates making these features available on lower tiers of Auth0's plans. Clerk bundles SCIM with each enterprise connection, while Auth0 separates connection creation from enablement. In terms of roles and permissions, Clerk offers simple organization roles, while Auth0 provides more complex, relationship-based authorization through its FGA system. Security-wise, Auth0 leads with a broader suite of advanced controls and certifications, while Clerk meets core security standards with a simpler offering. Reliability analyses show both platforms as dependable, with Clerk noted for its transparency in incident reporting. The summary also mentions that Auth0 is backed by Okta, enhancing its deployment and compliance capabilities.
