SSO (Single Sign-On) is the user experience of logging in once to access multiple applications, while SAML is an XML-based protocol that enables SSO by securely transmitting identity data between identity providers and service providers. SAML handles authentication (proving who you are) but not authorization (what you can access), which typically requires OAuth or RBAC. Implementing enterprise SSO involves managing SAML parsing, directory sync via SCIM, multiple identity providers, and certificate rotations. Critical security considerations include MFA enforcement, avoiding single points of failure, proper logging, and maintaining admin bypass mechanisms.
