FNET is offering a very unique network security solutions to the market.Totally different from current software-based solutions, it is defined as follows; to raise the network security level by getting rid of all the access to internal network through physical isolation between networks. From a network security prospective, the highest level of security is to physically isolate the sensitive systems from the network. At this point of view, it is possible to realize one-step upgraded security by physically dividing at the network topology.The bottom line is that internal servers are physically disconnected with the Internet whether the clients are on the internal or external network. Cutting the path for the unidentified external users to go through the internal systems makes it clear that substantial network security is provided in a way that is quite different from a logical security solution grounded in software.
