Open-Source Network Security Options

Free and open-source software (FOSS) is readily available in the networking space. From firewalls to VPNs there are a number of commercially-supported open-source network security options available. This CSO Online report highlights three examples of FOSS solutions that offer enterprise support.

“Untangle is a feature packed UTM network security solution with a comprehensive set of security features: firewall, VPN (OpenVPN/SLL), routing, QOS, anti-malware defense, anti-phishing, anti-spam services, intrusion prevention, and Web content filtering. Its simple web GUI uses the metaphor of a rack allowing for quick and easy management of all aspects of the system. Enhanced reporting with interactive drilldown allows you to get a bird’s eye view of what’s going on in your network as well as export data to PDF/HTML.

“General management features like automatic software updates for its core and associated signatures are welcome additions to any network/security administrator. The product comes in an open source edition (with all the features above). There are several commercial bundled versions that cater to SMB and educational environments. Commercial add-ons such as Commtouch, for enhanced spam blocking, an enhanced policy manager, commercial Web filtering solution from eSoft, WAN load balancing and failover, an active directory connector, and Kaspersky anti-virus vastly expand the offering.”
