Which user authentication methods are supported by Zscaler?

The correct choice highlights the variety of user authentication methods supported by Zscaler, which includes SAML (Security Assertion Markup Language), Active Directory, ADFS (Active Directory Federation Services), and multi-factor authentication (MFA). This multifaceted approach enables organizations to implement robust security measures by integrating with existing identity providers and allowing greater flexibility in user verification.

SAML is a standard used for single sign-on, enabling users to log in using their credentials across different applications without needing to enter them multiple times. Active Directory and ADFS facilitate integration with on-premises or cloud-based directory services, making it easier for organizations to manage user identities and permissions cohesively. MFA enhances security by requiring users to provide multiple forms of credentials, making unauthorized access much harder.

The other options do not capture the full range of authentication methods that Zscaler supports. Static passwords only do not reflect modern best practices in security, which advocate for stronger authentication measures. Biometric scanning and facial recognition, while innovative, are not standard features offered by Zscaler. Finally, stating that only MFA is supported overlooks the crucial integration capabilities with various identity providers that increase user convenience and security.
