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. Using configuration sets for Security Policy you define how your computer is connected to the local network and the whole Internet. Your computer may be completely hidden from any unfriendly attempts to access your hard drive while you are able to access any web sites you want and you decide on which applications are allowed to access Internet and which are not. With Jetico Personal Firewall you feel secure, safe and protected while enjoying all Internet activities.
