The key feature of any effective firewall is the stateful inspection of packets. Kerio Personal Firewall (KPF) inspects all traffic entering and leaving the desktop to ensure only authorized communication is permitted. KPF will block all inbound traffic by default, rendering the system invisible to random scans by hackers.

KPF requires the user to authorize any new connection attempts; creating a rule to permanently approve or block a connection attempt is as simple as checking a box. KPF filters by application, so you can approve Internet Explorer and deny spyware. To prohibit a Trojan horse from posing as a trusted application, KPF assigns a digital signature to each program. The system alerts the user when the signature for a program does not match. Advanced users can edit and add rules manually, set KPF to log specific rule-based traffic, and view all open connections from the Firewall Status interface.

Some programs that take control of desktops for malicious purposes, do so by installing drivers at the kernel level of the operating system. Kernel level drivers can bypass firewall rules because they operate at the same level as the firewall. KPF detects the attempt to install such drivers, warns of the potential threat and asks if the user would like to deny the activity.

Kerio Personal Firewall includes an auto update feature, which notifies the user when a new version is available for download. Corporate customers will appreciate the option to load a configuration file from a remote location when setting up multiple systems with the software. The syslog and remote administration capabilities in KPF help corporations manage remote users who connect to the internal network via a VPN connection.

"Kerio Personal Firewall is a must for desktop computers with always-on Internet connections, whether in a home or office environment," says Martin Viktora, CEO of Kerio Technologies. "Anti-virus software, although vital, is insufficient to protect from data theft or denial of service attacks. KPF keeps system files and resources out of the hands of wrongdoers, while allowing full access to the benefits the Internet can provide."
