What is one key aspect of Zscaler acting as a DNS resolver?

One key aspect of Zscaler acting as a DNS resolver is its ability to intercept DNS requests for processing. This functionality is crucial because it enables Zscaler to apply security policies directly at the DNS level. By intercepting DNS queries, Zscaler can filter out malicious domains, enforce safe browsing policies, and direct users to safe resources, thereby adding a significant layer of security to the network. This interception is essential for ensuring that DNS resolution not only points to the correct IP addresses but also adheres to the organization’s security posture.

The ability to process DNS requests this way is fundamental to Zscaler's cloud-based approach to security, where traditional on-premises configurations would not be effective. It showcases how Zscaler leverages cloud capabilities to enhance security while maintaining user experience.
