What is an SSO Provider?
An SSO provider is an identity platform that allows users to authenticate once and securely access multiple systems across SaaS, internal, and partner applications. The most effective sso vendors combine identity federation, adaptive access controls, policy enforcement, and operational reliability.
In practice, single sign on companies differ widely in how they handle architecture ownership, integrations, compliance, and support models.
How we ranked the top SSO providers in 2026?
