Palo Alto

The Palo Alto Next Gen Firewall can be configured to redirect users to Kasm by utilizing custom Response Pages for URL Filtering block, override or continue actions. Administrators may desire to restrict users from accessing certain URLs or categories directly, and instead present users with a special Response Page with the option to visit the link in isolation via Kasm, or even automatically redirect them.

Please consult the following vendor documentation for configuration steps. https://docs.paloaltonetworks.com/pan-os/8-1/pan-os-admin/url-filtering/url-filtering-concepts/url-filtering-response-pages.html

Below are example block pages that may be used to redirect users.
