Enterprise SSO and SCIM for B2B SaaS in 2026: WorkOS vs Auth0 vs Clerk vs Cognito

B2B SaaS

The first enterprise deal usually arrives with a security questionnaire that asks for SAML single sign-on, SCIM user provisioning and an audit log, and it is the moment many B2B products discover their auth was built for consumers. The four common ways to add it price very differently: WorkOS per connection ($125 a month each for the first fifteen, falling with volume), Auth0's B2B plans (from $150 a month), Clerk's B2B add-on ($100 a month on top of a plan), and Cognito per federated user ($0.015 per SAML or OIDC MAU after 50 free).

What the first enterprise customer will ask for

SAML or OIDC sign-in with their identity provider, enforced so their users cannot bypass it with a password. SCIM, so leavers lose access the moment IT disables them. Role mapping from their groups. An audit log of administrative actions. And, increasingly in 2026, a policy for AI agents acting on their users' behalf — which is where Cross App Access support is starting to appear on questionnaires. Price the connection model against the deal: a $125-a-month connection is trivial in a $30,000 contract and decisive in a $3,000 one.

Which should you use?

Question 1 of 1

Will enterprise SSO be in most of your contracts?

Our verdict

Choose WorkOS if enterprise customers are central to your plan: predictable per-connection pricing you can pass into contracts, an admin portal your customers' IT teams configure themselves, and SCIM done well. Choose Auth0 B2B if you need its wider feature set across both consumer and business users. Choose Clerk's B2B add-on if you are already on Clerk and your enterprise needs are modest. Choose Cognito if you are on AWS and price-sensitive at small numbers of enterprise users — but plan to build the self-service admin experience and SCIM handling yourself.
