Surely the answer is not putting data on laptops?
OK, so you may need things like email and document management system cache files to speed up your work (encrypted, naturally) but anything else should only be an encrypted copy of a document held in the organisation's data centre or "in the cloud" if you're into that sort of thing.
In other words the data on a laptop should be a tiny snapshot of some data that is already in a central location, not the other way around. Or are this company trying to encourage corporates to store more of their confidential and important data on laptops?
