The G-Server is the only hardware in this Group Test - all the other products consist of software. It is designed to be installed inline between the DMZ port on your firewall and a public web server. It is completely transparent and requires no changes to any network settings on other network equipment. It has no IP address visible to the outside world, so is undetectable by hackers. Even the MAC addresses of its NICs reflect those of the real web server to make the G-Server even more transparent. Two G-Servers may be configured for high availability.
