The Sunbelt Kerio Personal Firewall helps control how computers share information with other computers through the Internet or a local network. It also protects computers from external or internal attacks from other computers. The Personal Firewall is especially useful for laptop computers since they are easier to compromise because of built-in wireless access.

Basically, a firewall is a program that protects one computer from other computers. It examines information that tries to enter a computer from an outside source (i.e. the internet), and determines if the information is safe or harmful.

Here are some key features of "Kerio Personal Firewall":

· Stop all traffic – stops all traffic on the computer. This function can be helpful especially when undesirable or strange network activity is detected. Traffic can be restored after the appropriate security actions are taken.
· Logging – Each firewall module creates an independent log that is stored in a text file. Logs can be viewed in a configuration dialog. Logs can also be stored on a Syslog server.
· Connections overview and statistics – The overview provides information about established connections and ports opened by individual applications. Information on the current speed and size of transmitted data in both directions is also provided for active connections. The overview is automatically refreshed in predefined time intervals. Statistics show users the number of objects blocked by the Web content filter and the number of detected intrusions during specific time periods.
· Automatic update – Regular checks are made for newer versions of the firewall. Whenever a new version is detected, users have the option of downloading and installing it. It is also possible to check for new versions manually
