A company is implementing a vendor ' s security tool in the cloud.

The company should implement Security Assertion Markup Language (SAML) to integrate the vendor ' s security tool with their existing user directory. SAML is an open standard that allows identity providers (IdP) to pass authorization credentials to service providers (SP), enabling Single Sign-On (SSO). This allows the company to use its existing directory services for authentication, avoiding the need to manage a separate set of user credentials for the new tool.
