Kerio Personal Firewall (KPF) is a software agent that builds a barrier between your personal computer and the Internet. KPF is designed to protect your PC against attacks from both the Internet, and other computers in the local network.
KPF controls all data flow in both directions – from the Internet to your computer and vice versa, and it can block all attempted communication allowing only what you choose to permit. This makes KPF an ideal solution for notebook computers that freely travel in and out of the corporate network, facing exposure to various risks as they connect from different locations.

Kerio Personal Firewall protects against:
- information theft, modification or destruction
- Trojan horse applications
- spyware
- unauthorized access from within the local network
- denial of service attacks to applications or services
New features in version 4.0:
- enhanced packet filter - define unlimited number of protocols, services, address groups, time intervals, etc.
- firewall can be configured by simply permitting or denying communication to applications - suitable for beginners and less experienced users who do not want to use the advanced packet filter
- Intrusion Detection System
- System Security - applications on the desktop protected against being rewritten, modified or misused by other applications, etc.
- new status reports in the administration Window - traffic chart, connections, etc.
many enhancements in performance and load on the memory, especially in the kernel part of the engine

========================
- fixed several bugs on packet filter: rule creation, rule movement, groups
- fixed always on top for admin console
- fixed missing dialup numbers in trusted zones
- fixed logging in system security
- fixed configuration import/export
- fixed crash, when using large number of network rules
- fixed logging of NetBios
- fixed bug caused crash in conversion tool
- fixed processing ICMP protocol events
- default entries no more resets to their defaults in application table upon
startup
- packet filter rules were used in impropper order
- kpf now automatically permits update checker queries when using http proxy
- loopback entry in Trusted Area cannot be editted any more (it was useless
since loopback is alwas the same)
+ improved use of packet filter list (enabling/disabling, rule movement, added
directions, log, alert)
+ added IP groups to packet filter
+ improved stability to communication between gui and service
+ added tooltip statistics on the chart
+ redesigned main System security page
+ enabled stream support in driver (for testing - related functionality will be
added later)
+ added crashdump contents in assist.exe
+ possibility to enable/disable security modules (Network security, System
security, IDS)
+ improved importing - it is possible to import 2.x rules directly from KPF
Admin console
+ organization changes in config file may cause lost of several settings when
upgrading: "Enable network security", "Disable predefined network security",
"Stop Traffic", and some minor right click menu admin settings (port, address
resolving), rules stay unchanged!!
anyway i like KPF for long time since 2.1x
