Set up HTTP filtering

Secure Web Gateway allows you to inspect HTTP traffic and control which websites users can visit.

​​ 1. Connect to Gateway

To filter HTTP requests from a device:

  1. Install the Cloudflare root certificate on your device.
  2. Install the WARP client on your device.
  3. In the WARP client Settings, log in to your organization’s Zero Trust instance.
  4. Enable the Gateway proxy for TCP. Optionally, you can enable the UDP proxy to inspect all port 443 UDP traffic.
  5. To inspect HTTPS traffic, enable TLS decryption.

​​ 2. Verify device connectivity

  1. In Zero Trust, go to Settings > Network.
  2. Under Gateway logging, enable activity logging for all HTTP logs.
  3. On your device, open a browser and visit any website.
  4. In Zero Trust, go to Logs > Gateway > HTTP.
  5. Make sure you see HTTP queries from your device.

To create a new HTTP policy, go to Gateway > Firewall Policies > HTTP in Zero Trust. We recommend adding the following policies:

​​ Bypass inspection for incompatible applications

Bypass HTTP inspection for applications which use embedded certificates. This will help avoid any certificate pinning errors that may arise from an initial rollout.
