What does Samsung’s Knox add to the security of Android devices?

Samsung adds their “Knox” security technology to many (most?) of their devices and use it as a selling point. What does it do that isn’t already done by the Android OS? I assumed that this was a marketing gambit, but apparently Samsung Knox has received US Dept. of Defense certification, so it looks like I was wrong about it. What exactly is Knox and what does it actually do to improve the security of Android phones and tablets?
Samsung Knox

"Samsung Knox provides security features that enable business and personal content to coexist on the same handset. The user presses an icon that switches from Personal to Work use with no delay or reboot wait time.[1] The manufacturer has claimed this feature will be fully compatible with Android and Google and will provide full separation of work and personal data on mobile devices and "addresses all major security gaps in Android."[2]

The Knox service is part of the company's "Samsung Approved For Enterprise" (SAFE) offerings for smartphones and tablets. Samsung Knox’s primary competitor is Blackberry Balance, a service that separates personal and work data. The name, Samsung Knox, is derived from Fort Knox.[3]

In October 2014, U.S National Security Agency (NSA) approved Samsung Galaxy devices under a program for quickly deploying commercially available technologies. Approved products include Galaxy S4, Galaxy S5, Galaxy Note 3, Galaxy Note 10.1 2014.[4]"
