ClearOS is a Linux firewall distribution, based on CentOS and Red Hat Enterprise designed for use in small and medium enterprises. ClearOS is based on CentOS and Red Hat Enterprise Linux, which is designed to be deployed in small and medium businesses as a Gateway & Server with an intuitive graphical web based user interface.
