Jetico Personal Firewall Version 2.0.0.35 is recently released. It is a pretty effective security program that protects your computer from being attacked by hackers externally and bars disturbance from malicious programs that hide inside your computer’s memory and hard drive internally. This security software gives you three levels of protection: low-level network packets filtering, application-level network events filtering and filtering of user-level processing activity. This personal firewall will check every packet that flows in or out of your computer. It comes with a lot of excellent built-in documentation and it is quite a useful budget security solution. Having said that, this application is not so suitable for internet newbies or users who don’t really understand how applications and devices interact with the internet. This is because Jetico Personal Firewall will require you to do some configuration before using it. The wrong configuration might prevent you from running your other applications.

Jetico Personal Firewall’s 30-day trial version can be downloaded free of charge. Get the 3.2MB installation kit from Jetico download centre. As usual, after installing it, you will be led to Jetico Personal Firewall Configuration Wizard. You can configure your firewall step by step via the wizard. Once it is done, you need to restart your PC. You will thence be directed to the Jetico Personal Firewall window. There are 5 tabs there: Network Traffic, Application, Log, Group and Configuration. The Network Traffic Area will display to you a graphical view of incoming and outgoing traffic. In the Applications area, you will find the running programs and details about their network and internet connections. You can customize items shown there by right clicking on the bar containing their names and check/unchecking them using the contextual menu that appears. In the Log area, you can see every system event being monitored. The Groups are used by the program as parameter values for the firewall’s rules. Creating new groups and editing existing ones is as easy as it gets, and if you run into any problem, you can use the excellent documentation that comes with the program. In the Configuration area, you can make adjustment to filtering settings. However, if you don’t want to waste time on individual programs, you can block or allow the traffic by applying some general rules.
