The Sunbelt Personal Firewall helps you control how your computer exchanges data with other computers on the Internet or local network. Even if you have a router that has a built-in firewall, you will still benefit from using Sunbelt Personal Firewall on your PC(s). It's the principle of "belt-and-suspenders" (being double-safe) which is a strongly recommended strategy to deal with these 'Internet Bad Guys'. The Sunbelt Personal Firewall also protects your PC from attacks initiated by other PC's on your network that might have been compromised. Sunbelt Personal Firewall is a necessity for all desktop computers connected to broadband Internet, using DSL, cable, ISDN, WiFi or satellite modems. Within an organization, Kerio Personal Firewall prevents a single computer from attacks initiated by internal users. Remote workstations and laptops running KPF are protected from Internet born attacks. And if you have a notebook PC, you definitely should use the Sunbelt Personal Firewall on that notebook as well. Notebooks are especially easy to compromise because of built-in wireless access.

Potential intruders use various techniques to find out if your PC is vulnerable to attacks. These techniques vary from simply scanning all the entry points (called 'ports') of your computer to far more sophisticated methods. But the Sunbelt Personal Firewall has a built-in intrusion prevention system that identifies and blocks both known and unknown attacks so you can breathe easy and enjoy surfing the web. It really is an essential element of your Internet Safety.
