Couple of things, which I am aware of here -- the browser they have is currently is for iOS and Android only..and since this comes with an MDM solution, what you can do is :
1. Block the usage of native browsers ( e.g. Safari on iOS)
2. Disallow installation of other browsers, i.e. disallow installation of other browser apps like Chrome, Opera etc)
My suggestion would be to get in touch with the folks at MaaS360 (they are pretty responsive) and take a free-trial. Since theirs is a purely cloud based solution, you really don't need to worry about installing stuff in your network for the trial or later.
