Introduction to “external-sso-5.1.3.62-webdeploy-k9.pkg” Software
The “external-sso-5.1.3.62-webdeploy-k9.pkg” represents Cisco’s latest implementation of External Single Sign-On (SSO) integration within the Secure Client ecosystem. Designed for enterprise network administrators, this web deployment package enables centralized management of VPN authentication through third-party identity providers like Azure AD or Okta.
