A cloud-based web proxy is blocking key sites that a business requires for operation. After validation, the sites are legitimate, and access is required for end users to complete their work. Which…

Instructing users to bypass the cloud-based web proxy undermines the entire security purpose of having a proxy and can expose the network to unmanaged risks.

Whitelisting the URLs specifically instructs the cloud-based web proxy to permit access to those validated, legitimate sites that were previously blocked. This is the most direct and secure method to ensure necessary business access while maintaining the protective function of the proxy for other, unapproved sites.

Blacklisting URLs specifically prevents access to malicious or unwanted sites; it would further block, not allow, access to the required legitimate sites.

Creating a security group for users and enforcing MFA enhances user authentication and authorization but does not directly control URL access through a web proxy or resolve the issue of legitimate sites being blocked.
