It is a need of every organization to protect their network from virus, fishing, adds, and some unwanted sites at work place some of the organizations wants to control bandwidth and limits the usage of Internet with in organization.

There are many alternatives of such proprietary software, Untangle is one of then. Untangle is the only multi-function firewall solution to offer everything you need as an “application” that you can turn on or off from a virtual rack – radically simplifying network management. Apps are available individually or in packages and work together to accomplish your goals.

Untangle is an opensource solution, but unlike the other opensource it have Community and Enterprise two different versions both versions have the same rack but they are differentiate in term of Free Apps and Paid Apps on the rack. I am not going to discuss about what are the popular paid apps by Untangle but how we can use free apps efficiently just for paying cost of hardware. In order to install Untangle you need a separate computer with minimum 2 LAN cards.

Good to pay less for 70% – 80% requirements satisfaction, Rather to pay hugs for more then 100% requirements.
