Duo Access Gateway¶
About¶
Duo Access Gateway is an on-premises solution that secures access to cloud applications with your users’ existing directory credentials (like Microsoft Active Directory or Google Workspace accounts) using the Security Assertion Markup Language (SAML) 2.0 authentication standard. SAML delegates authentication from a service provider to an identity provider, and is used for single sign-on (SSO) solutions.
