SAML

What it is:

SAML is an XML-based open standard for exchanging authentication and authorization data between identity providers (IdPs) and service providers (SPs). It enables Single Sign-On (SSO) by allowing users to authenticate once and access multiple applications without re-entering credentials. In modern Identity and Access Management (IAM) and Customer Identity and Access Management (CIAM) systems, SAML is a key protocol alongside OIDC and OAuth2 for federated identity.

Why it matters:

For enterprises and regulated industries, SAML simplifies access management, reduces password fatigue, and strengthens security by centralizing authentication. It is critical in hybrid IT environments where legacy systems coexist with modern cloud applications. Many banking, insurance, and gaming platforms rely on SAML for integrating workforce and customer applications, ensuring compliance with industry standards and enabling seamless identity federation during IAM Modernization and Cloud Migration initiatives.

How it works:

• Authentication Flow: When a user attempts to access a service, the SP redirects the request to the IdP. The IdP authenticates the user and generates a SAML Assertion—a digitally signed XML document containing the user’s identity and access attributes.

• Assertion Exchange: The SP validates the assertion and grants or denies access based on the attributes provided.

• SSO Enablement: SAML supports seamless SSO across applications by passing trusted identity information between systems without exposing user passwords.

• Integration Flexibility: Works with both Hybrid Identity setups and cloud services, and can be combined with MFA, FIDO2, and Adaptive Security for stronger authentication journeys.
