Works on Windows 2000. For example, the user is encouraged to disable file sharing. Disadvantages All outgoing traffic is passed. It should be possible to define rules that block specific traffic, but I was unsuccessful in my attempts to block outgoing SSH, for example. Understanding where and how to edit rules is not easy.
Documentation is poor.
I could find no detailed information of what the product does on the website. There is online help, but it is limited. It seems probable that the user would hit green thinking that the firewall is active in this state. The GUI is neither the best or worst of products tested so far. Each alert can generate a small window, but this is tiring and will be disabled by most users.
