Jetico Personal Firewall software provides you with security against hackers who try to access your PC when you are connected to the Internet. Having inherited the Open architecture principles from BestCrypt, the Jetico Personal Firewall allows you to construct a strong yet accurate security policy and provides clear control over your network connections.
Low-level (Network packet filter)
This checks the validity of network packets and parameters such as source & destination addresses, protocol, etc. Using this process, Jetico Personal Firewall can make your computer invisible to a non-trusted network. By selecting the Optimal Protection Policy, your computer becomes "stealthy". Any security probing tests (for example, ShieldsUp! tests) by internet hackers will report that your computer does not exist.
Application-level (Network events filter)
This checks and enables you to monitor network/internet connection requests made by applications. If you are not sure why an application wishes to send or receive data from the Internet you can limit or block the activity.
User-level (Process activity filter)
This notifies you of and prevents dirty tricks by Trojans and other malicious programs. (A Trojan can inject its own code into programmes on your computer and send data about you to a third party. e.g. a Trojan in Internet Explorer could transmit details of your browsing preferences.)
