WHY Use a Security Gateway to Protect your Network Perimeter?

Many organisations connect to the internet using a basic router which usually provides minimal or no control over who or what is using your internet connection.

They also can allow traffic from the Internet through to your internal systems, often with only rudimentary control that provides little or no protection for your internal systems, and with little or no sensible method of monitoring what is happening at your network perimeter.

At ethernal we particularly recommend the range of security gateways from Sophos and as a Sophos Cerified partner can supply the full range of SOPHOS security gateways.
