An Internet Firewall reduces the risk of having your computer broken into and used, without your knowledge, to attack other computers, distribute spam, pornography, etc. The “hacker” who breaks into your computer could also look at the files on your machine and the files on machines connected to your computer.
ADSL customers using an adsl router can protect themselves by having their router also configured as a firewall. Customers using a modem/bridge will need to provide their own firewall device. Please consult one of our partners about stand alone or sophisticated firewalls.
