ClearOS (formerly named ClarkConnect) is a Linux distribution, based on CentOS and Red Hat Enterprise Linux,[3] designed for use in small and medium enterprises as a network gateway and network server with a web-based administration interface.[4] It is designed to be an alternative to Windows Small Business Server.[5] ClearOS succeeds ClarkConnect. The software is built by ClearFoundation, and support services can be purchased from ClearCenter.[6] ClearOS 5.1 removes previous limitations to mail, DMZ, and MultiWAN functions.[7]

As of the ClearOS 6.1 release, the distribution is a full-featured operating system for servers and workstations built from source packages for Red Hat Enterprise Linux.[8][9]
