Server not only shares most of the features & strengths of Proxy Server, but it also builds on them. The result is a scalable, enterprise-ready product that will be widely adopted by plenty of corporations. Although easy to install, ISA Server is also a complex product that requires skill & knowledge to implement properly. it is also a very serious product that plays a critical role in your network infrastructure. ISA Server is not the kind of product you set up on your production network to play with or take lightly. Nor is it the kind of product that is necessarily easy to use or implement; it is certainly not the kind of product that is going to give you everything you require simply by virtue of having it installed & connected to your network.
