Jetico Personal Firewall v.1

Jetico Personal Firewall v.1 is the most powerful and flexible personal firewall for legacy Microsoft operating systems. It supports Windows 98/Me/NT/2000/XP operating systems. Take a look at firewall leak test results:

Jetico Personal Firewall is designed to give the user full control over the networking subsystem. The key principles are rule based stateful filtering, open configuration, detailed logging and live statistics.

Open configuration means: no hidden rules or dependencies. User can inspect and modify every bit of Jetico Personal Firewall configuration. In conjunction with rule based filters it gives the user unpreceded control over network related events. Fine grained logging and statistics simplify both network events and firewall configuration analysis. The unique live statistics display which firewall rules are applied in the realtime.

All these things combined together makes more that powerful firewall - the ultimate tool to protect and monitor your system.

And the last, but not least: Jetico Personal Firewall v.1 is FREE!
