Advanced security settings

You can inspect only untrusted content or all content in the traffic.

  • Inspect untrusted content: Inspects traffic from untrusted sources or traffic going to untrusted destinations only. This setting gives the best performance.
  • Inspect all content: Inspects all content to and from both trusted and untrusted sources and destinations. This setting gives the best security but may impact performance.

Note

The difference in performance between Inspect untrusted content and Inspect all content is minimal. However, it can be significant in high-traffic environments.
