What is a reason for deploying a ZIA Private Service Edge?

Deploying a ZIA (Zscaler Internet Access) Private Service Edge primarily facilitates the preservation of the source IP address. This feature is crucial for organizations that rely on specific security policies or logging requirements tied to the user's original IP address. When users route their traffic through the ZIA Private Service Edge, the service can maintain the source IP, which allows for proper identification and management of users from the perspective of security appliances and applications across the network.

This capability enhances security and compliance protocols, as it enables organizations to handle traffic and apply policies based on the true source of that traffic rather than the IP address assigned during the routing through the cloud service. It also supports scenarios where original IP visibility is essential for analytics and auditing.

While the other choices describe aspects that are more about benefits or functionalities that might come with deploying edge solutions, they do not directly address the critical function of source IP address preservation.
