Microsoft's pointed out that the United States' National Security Agency has added some Surface devices to the nation's okay-for-accessing-secure-information list.

That list's proper name is the Commercial Solutions for Classified Program and was created because the US government used to spend years building a secure suite of products before releasing them to government users.

That approach would leave workers wielding out-of-date technology, which didn't exactly help US government workers to become efficient.

Microsoft's the only laptop and desktop OS vendor on the list, but is hardly alone on the list for mobile devices. Apple, LG and Samsung devices all make it, as do Blackberry OS 10.3 and the Boeing/Blackberry “Black” Android collaboration. The rest of the list covers all manner of enterprise hardware and software and offers a who's-who of big-name tech vendors.
