ConfigServer.com (ConfigServer Firewall) will permanently close on August 31, 2025. The ConfigServer CSF firewall has been a trusted tool for Linux server administrators for many years. Unfortunately, ConfigServer has announced that it will discontinue its services on this date, and there will be no further updates, downloads, or support available after that. This news has saddened many in the hosting community, including us. CSF/LFD has become the standard security layer for countless servers due to its simplicity, reliability, and extensive feature set.
Fortunately, CSF will continue to run on servers even after the vendor’s closure, however, it will not receive any updates or support.
Exciting news! The developers of ConfigServer have released some of their most popular scripts under the GPLv3 license, and they are now available on GitHub.
