What does Zscaler DNS resolution primarily do?

Zscaler DNS resolution primarily functions by intercepting and redirecting DNS requests to the Zscaler cloud. This approach enables organizations to route all DNS queries through Zscaler's security infrastructure, ensuring that every request is subject to security policies and inspections. By handling DNS resolutions in the cloud, Zscaler allows for improved security posture, agency over DNS traffic management, and enhanced visibility into DNS-related data, which are critical aspects of modern security strategies.

While local DNS settings can be bypassed to ensure proper routing, the core capability lies in redirecting the requests and processing them in the cloud. This method not only strengthens security by enabling real-time threat intelligence to be applied to the requested domains but also enables organizations to enforce policies based on the destination of DNS requests. Consequently, organizations gain real-time insights and protections against potential DNS-based threats, ensuring a secure and compliant digital environment.
