ConfigServer Firewall, often called CSF, is a popular tool for making servers safer. It helps to control the traffic coming in and going out of your server. You can easily turn CSF on or off to make your server more secure. This lets you adjust your firewall settings as you like. This guide will show you how to turn ConfigServer Firewall on or off in WHM.
ConfigServer Firewall is not managed by cPanel Software; it's a separate security tool. If you encounter problems with ConfigServer Firewall or if it causes issues with cPanel Software, we may ask you to turn it off temporarily for troubleshooting.

Note: This option won't appear if you've uninstalled CSF from your VPS or dedicated server. If you're using AccuWebhosting VPS or a dedicated server, it may not be visible because we've disabled it for security reasons.
