carrying a normal laptop around might not be allowed, to prevent someone dumping data and carrying it out
I work in avionics, I have this kind of restrictions, but it's not a problem at all.
You use either SunRay terminals in laptop shape, that do wifi bootstrap from Solaris servers (and only run Java), or you use laptops that do network bootstrap, they have no internal storage device, and have all the expansion ports sealed. So, no USB ports available.
These laptops only run approvd testing applications.
In addition to the fact that you can't bring personal laptops, and that every authorized laptop must have a tag approved by the security department, all things that are regularly checked by the security guys.
So, a product like this, on the other hand, seems to me to be a serious security flaw, for the simple fact that it forces one to have to grant an account.
