Firewalls

The firewall is the first line of defence for your network and its primary function is to regulate the flow of traffic between your network and other networks. In its simplest form this will allow all traffic from your network out, whilst blocking all other traffic from coming in.

In addition to this the firewall can perform many other functions including VPN termination using dedicated processors, Content Filtering using dedicated modules, Intrusion Prevention and Anti-Virus services.
DIS can supply, install and support a range of industry leading firewall products.
