Traffic Inspector is a comprehensive UTM solution. Stateful firewall, Web Access Policy system, antivirus protection, spam filtering, traffic shaping, advanced routing, traffic accounting and reports - you name it, TI has it. There are other analogous solutions out there, but all of them are usually separate products.
Traffic Inspector will run on an ordinary PC meaning you don't need expensive hardware. Traffic Inspector is also a Microsoft Windows-based product. What that means is that you do not need to be a network / Unix / Linux guru to configure and administer the program. Review collected by and hosted on G2.com.
I sure have seen prettier interfaces. Administration Console which is used to control the program is nothing but a heavily modified MMC snap-in. But hey, it is about functionality, not about pretty buttons, right? Review collected by and hosted on G2.com.
