In our organization internet management was a big issue, since we had no budget allocated to Internet management I was worried? How should I control our internet usage? Tried to convince the management to buy content filtering appliances, unfortunately they had no budget and our users had no control and they were enjoying the freedom of internet. I started looking for open source appliances and came across Untangle. Which proved to be great for us to control our users? (Who were not happy)? By installing this open source network gateway we could manage to block most of the unwanted contents, P2P applications and much more.
