SAML is an XML-based standard for web browser single sign-on and is defined by the OASIS Security Services Technical Committee. The standard has been around since 2002, but lately it is becoming popular due its advantages:

• Usability - One-click access from portals or intranets, deep linking, password elimination and automatically renewing sessions make life easier for the user.
• Security - Based on strong digital signatures for authentication and integrity, SAML is a secure single sign-on protocol that the largest and most security conscious enterprises in the world rely on.
• Speed - SAML is fast. One browser redirect is all it takes to securely sign a user into an application.
• IT Friendly - SAML simplifies life for IT because it centralizes authentication, provides greater visibility and makes directory integration easier.
• Opportunity - B2B cloud vendor should support SAML to facilitate the integration of their product.
