"This approval enables other government agencies and regulated industries such as healthcare and financial services to adopt Samsung Galaxy smartphones and tablets," he said.
"This is a significant milestone for Samsung as we work to grow our relationships within government and large corporate enterprises."
The Samsung Galaxy S4, which launched on 26 April is the first smartphone to support Knox. The device has the software shipped with it, but it is yet to be activated in regular handsets.
