There are many companies that are using windows kiosk to provide people an alternate way to provide automated customer service. These kiosk are even developed sometimes by the same company.

How to tell if they provide enough security level? When I have had to answer that question, I have found useful iKAT, which is a tool to test how secure is a Kiosk by telling if it can spawn a shell or other programs, crash the browser, navigate to forbidden sites, among many other interesting plugins. You can also find iKAT for Linux.
