ConfigServer Ltd officially announced its permanent closure on August 31, 2025, which resulted in the shutdown of its website and all related services. However, you can still use CSF – ConfigServer Security & Firewall via GitHub. In this guide, we’ll cover how to install CSF and the essential security steps after updates are discontinued.

Prerequisites

Before you start: Make sure you have:
• Full (root) access to the server
• A supported Linux OS (CentOS, AlmaLinux, CloudLinux, Debian, Ubuntu)
wget installed on the server

What happened to ConfigServer?

  • Company officially closed on August 31, 2025.
  • License servers for paid products (CXS, MSFE) were disabled.
  • CSF still works but with no support or future updates.
  • The last available version is hosted on GitHub:

How to Install CSF from GitHub

  1. Download the package:
wget https://raw.githubusercontent.com/waytotheweb/scripts/refs/heads/main/csf.tgz
  1. Extract and enter the folder:
tar -xzf csf.tgz
cd csf
  1. Run the installation script:
sh install.sh
  1. Verify the installation:
csf -v

If the version number appears, the installation was successful.

Important Step: Disable Auto-Updates

Security Warning: Since ConfigServer’s update servers are offline, you must disable auto-updates to avoid:
• Daily error messages when failing to connect
• The risk of old servers being hijacked as malicious update sources
Method 1: From Control Panel (WHM or DirectAdmin)
  1. Go to CSF settings.
  2. Set the option to: AUTO_UPDATES = OFF
  3. Save changes and restart CSF/LFD.
Method 2: From the Command Line (CLI)
  1. Edit the configuration file:
nano /etc/csf/csf.conf
  1. Find the line: AUTO_UPDATES = "1" and change it to:
AUTO_UPDATES = "0"
  1. Restart CSF/LFD:
csf -r
systemctl restart lfd

Integration with Control Panels

CSF remains fully integrated with panels like WHM and DirectAdmin, allowing you to manage it through the GUI as before.

Conclusion

The closure of ConfigServer Ltd does not mean the end of CSF. The tool is still available for installation and use via GitHub, but it’s critical to disable auto-updates to maintain security.
