Let’s say you have a high speed,always on internet connection and want all your computers behind a highly firewall, but for a highly-configuredable firewall and top of theline internet connection optimizer, you will want Microsoft internet security and acceleration server. ISA protects your network from hackers, improves internet performance for clients on your network, and controls clients access to the internet.
