run it, I was impressed to say at last.

However, for a small business owner where funds may be tight buying the commercial UTM appliance may be to expensive since asides from just buying the hardware, the service also requires yearly maintenance and subscription fees that can be from few hundred to few thousand of dollars depending on vendor, product and options.

I had recently came across the another company called Untangle. While they sell complete solution (including hardware and software) that can cost you few thousand dollars, unique thing about the untangle is that they offer almost entire software platform that forms the core of their technology, absolutely free of charge. With exception of few premium components you get the whole meal deal. And loading/configuring the platform is not that hard at all if you have a basic knowledge of network. A inexpensive PC (P3 1GHZ will run the platform OK although if you want to load all modules, a faster P4 with more memory is recommended).

Even better, if you have a fast PC with lots of memory and hard drive space, with few modifications (you need minimum 2 but 3 network cards are recommended) you can load a virtual image (Vmware image) to your computer and run it as surrogate install of your existing OS.

With this platform you get Anti Virus (single Anti Virus based on Open Source Clam AV engine is free of charge, the second AV engine is optional paid component), Anti Spam with SpamAssasin, Razor, Bayesian filters, DNSBL/RBLs, optical character recognition (OCR), tar pitting, custom tuning and updates components (same technology based on Open Source GPL model that other vendors utilize in their appliances that sell for several thousand of dollars up front and cost thousands of dollars in subscription fees per year to maintain and operate), Web Filter with full category listing of 50 plus categories to customize your unit plus custom allow and deny web sites based on URL, IP, etc. You also get Anti Phishing module, Intrusion Detection module, Firewall, Protocol Controll, Fully Controllable and Customizable Router and NAT gateway and more. To summarize it in simple terms, you are getting same level of protection that some other companies can easily charge you as much as $50 000 USD or more, absolutely free (if you do not count cost of hardware to load the platform and a bit of time you may spend configuring and customizing the platform).

By properly implementing the Untangle Server and configuring all of its defense
