Bittium's ToughMobile has some special hardware and a government certification (KATAKRI) to be used as a container of classified information. Finnish Defence Forces just bought a bunch of them.
It also comes with its own Secure Suite MDM and is not tied to any unwanted third party. It's quite expensive, though, and I have no first-hand experience of it. Just talked with some Bittium guys recently. Lots of former Nokians working there.
