EVERY business should have an industry standard, stand alone (ie not part of the router) firewall in place. The firewall is the first line of defence for your network, all your computers and data from attackers from the outside, whether they are viruses or hackers.
The firewalls we supply are proven to be the best in the business in independent tests the world over. They always get top marks for speed, effectiveness and ease of use. They can be installed in a short amount of time and you can be up and running AND SAFE very quickly.
