ClearOS (previously ClarkConnect) is a Linux distribution.
The purpose of ClearOS is to transform any standard PC into a dedicated firewall and Internet server/gateway. The software is a solution for small businesses, home offices, and networked homes.
ClearOS is based on CentOS and offers a very robust set of tools organized into easy to navigate administration pages. The administration pages are very similar to those that you would find with IPCOP and Smoothwall.
Features include:
- Firewall, Networking and Security:
- Provides several levels of security.
- At the network level, the firewall restricts access to your systems and provides advanced features, including DMZ, 1-to-1 NAT and Port Forwarding.
- At the protocol level, the Peer-to-Peer detection system lets you manage peer-to-peer file sharing usage.
- At the application level, the Intrusion Detection and Intrusion Prevention systems provide another layer of defense against threats to your network.
- Virtual Private Networking.
- Web Proxy and Content Filtering.
- E-mail, including Webmail.
- Groupware.
- Database and Web Server.
