Single Sign-On / Security Assertion Markup Language
Updated June 20, 2026 · Reviewed by Shorim Haniffanshoib, Head of Editorial — IT Strategy & Enterprise
SSO (Single Sign-On) is an architecture where a user signs in once to an identity provider (IdP) to access all corporate applications without needing a different password per app. SAML (Security Assertion Markup Language 2.0) is an XML-based protocol standard for exchanging authentication data between IdP and Service Provider — the most common protocol in legacy enterprise B2B, alongside the more modern OIDC/OAuth 2.0. For fintech, MNC, and sensitive (SOE, healthcare) RFPs, SSO/SAML support frequently appears as a mandatory technical requirement — the vendor dashboard must integrate via SAML to the client's Okta, Azure AD, Google Workspace, or OneLogin. Without SSO, the client's IT cannot enforce a centralized password policy and cannot instantly deprovision when an employee resigns — a major security gap in compliance audits.
SSO / SAML (Single Sign-On / Security Assertion Markup Language) frequently appears in B2B IT procurement contexts: SSO (Single Sign-On) is an architecture where a user signs in once to an identity provider (IdP) to access all.
