The firewall is a main component in the development of any cyber security system. It is the first line of defense against the incoming communication traffic on its way to the inner circles of the local LAN network.

The correct choice of firewall is a very important decision for the normal functioning of the cyber security system and the entire computer network because all the traffic going out of and into the network server resources, the customer workstations and the internet, passes through it.
The throughput of the firewall plays a major role in the amount of traffic that may go through it and how fast it can be inspected, which is of particular significance for ensuring the normal performance and future upgradeability of the information system.
