A firewall is a device that protects networks and computers that are
connected to the Internet.
 All the time that
your computers or network are connected to the Internet they are at risk from hackers and viruses.
Certain types of connection are inherently more risky due to the fact that they
are always-on (e.g. broadband connections).
A firewall
essentially filters network traffic being sent to your PC or network
whilst allowing your outgoing traffic to pass through. It can be used to block certain types of network traffic
leaving your network less vulnerable to attack.
It should not be
seen on its own as a panacea for network security, but should always be used in conjunction with
antivirus
software and a sensible security policy.

Firewalls vary
considerably in specification - and price - depending upon the size of the
business and the level of security and services required.
Home office users may opt to choose a personal firewall solution such as
ZoneAlarm,
whereas corporate users may benefit from using a standalone 'firewall in a box' such as the
SonicWALL firewall.
We can help you
navigate your way through this minefield and select the most appropriate
firewall solution for your business. Call us today to arrange a consultation.
