Jetico Personal Firewall protects your computer from unwanted hacker's attacks from outside as well as from malicious programs living secretly inside your computer's memory and hard drive. Three levels of protection are included: low-level network packets filtering, application-level network events filtering, and filtering of user-level process activity. Jetico Personal Firewall checks every packet that comes in or out of your computer.

Version 2.0.2.5 may include unspecified updates, enhancements, or bug fixes.
