ClearOS is a network and gateway server designed for small businesses and distributed environments. Based on CentOS, a clone of Red Hat Enterprise Linux, the distribution includes an extensive list of features and integrated services which are easy to configure through an intuitive web-based interface. Some of the tools found in ClearOS include antivirus, antispam, VPN, content filtering, bandwidth manager, SSL certification, and web log analyser, just to name a few of the available modules. The distribution is provided as a free download, inclusive of free security updates for 18 months.

Open Source and Free

Among other features, antivirus, antispam, VPN and content filtering are built right into the software -- no need for expensive third party add-ons. With ClearOS, you can avoid costly vendor lock-in and proprietary formats; instead, you can embrace open standards and protocols.
