Online Armor is a powerful, feature-rich and comprehensive personal firewall that monitors the connections and the processes of your system in order to protect it against external threats, attacks and intrusions.
One of the best things about this firewall is the fact that it features a handy self-learning rule engine. This means that Online Armor will automatically configure the firewall rules based on the programs that are currently in use. Anyway, it also offers an option to edit or create rules manually. The self-learning rule engine contributes considerably to the fact that this application is very easy to use. It’s one of the simplest and most intuitive personal firewalls that you can find. In spite of being easy-to-use, it’s pretty comprehensive, coming packed with a lot of features and additional functions. For example, it provides protection against keyloggers and against DNS spoofing attacks, and it enables you to control the programs that start automatically with the system boot up. A lot of other functions and features are also available.
On the other hand, the fact that it forced me into restarting the system after its installation, otherwise it wouldn’t have worked at all, was not the biggest problem I encountered while testing it. The fact that after the uninstallation of Online Armor, the default Windows firewall was switched to on and was blocking all my connections was quite annoying and made me lose a lot of time detecting the problem and fixing it. This made me be disappointed with this tool, otherwise I would have considered it a great personal firewall.
