Which of the following statements is true about external users?

The statement affirming that external users must connect to an Identity Provider (IdP) or SAML provider is true because external users typically require a means of validating their identity when accessing resources within a secure environment like Illumio. Identity Providers play a critical role in providing authentication services, ensuring that users are who they claim to be. By requiring an IdP or SAML provider, organizations can centralize user authentication, enforce security policies, and streamline access management for external users.

This approach not only enhances security through validated identity checks but also allows for integration with existing identity management systems, making it easier for users to authenticate using their credentials from recognized sources. Thus, connecting to an IdP or SAML provider is a fundamental step in managing external user access securely and efficiently.
