Personal Lite is rather unique
One reason I like Personal Lite is its uniqueness. I don't know of another client-side application that has all of the same features. As for trustworthy, AirDefense has a solid reputation and is used extensively by the DoD.
There are network-centric security applications hosted on Wi-Fi managing switches or controllers that poll all of the APs for security concerns. AirDefense and most enterprise Wi-Fi systems have that technology available.
In this article, I was trying to focus on the individual Wi-Fi notebooks that are vulnerable when public/hostile Wi-fi networks. Most Wi-Fi security applications aren?t setup like Personal Lite. Before Personal Lite, I used firewall or IDS applications to try and get similar results. The advantage to Personal Lite is that it?s designed specifically for Wi-Fi monitoring which I see as very helpful.
I'm sorry to not be of more help. If you describe your specific need, I should be able to get more detailed as to whether an enterprise solution would be a better fit or not.
