  2. Navigate to Settings > Browser Isolation.
  3. Enable Clientless Web Isolation.
  4. Configure permissions.
  5. Navigate to <authdomain>, complete the login and start using Browser Isolation.

Optional configurations

API setup

Clientless Web Isolation is implemented through a prefixed URL.



  • authdomain — Your organization’s Cloudflare Zero Trust team domain.
  • URL (optional) — Target URL to open in a remote browser. This parameter is optional — when not provided, users are presented with a Cloudflare Zero Trust landing page to input a URL or search for a website.


  • Authentication events. User login events are available in Access Audit Logs.
  • HTTP request logs. Traffic from the remote browser to the Internet is logged in Gateway request logs.


  • Integrating with a third-party Secure Web Gateway. Clientless Web Isolation can be integrated with a secure web gateway by implementing a custom block page.
