Samsung and BlackBerry recently announced that, following testing by the Defense Information Systems Agency (DISA), Samsung Knox-enabled devices (currently limited to the Samsung Galaxy S4), BlackBerry Z10 and Q10 smartphones, and BlackBerry PlayBook tablets have been approved for use on U.S. Department of Defense networks (h/t Computer Weekly).

"This approval enables other government agencies and regulated industries such as health care and financial services to adopt Samsung Galaxy smartphones and tablets," JK Shin, president and CEO of IT and Mobile Communications for Samsung Electronics, said in a statement. "This is a significant milestone for Samsung as we work to grow our relationships within government and large corporate enterprises."

"BlackBerry 10 is ideal for our government customers because it offers a rich, highly responsive mobile computing experience, along with BlackBerry's proven and validated security model -- a combination that’s unmatched in the industry," Scott Totzke, senior vice president for BlackBerry Security at BlackBerry, said in a statement. "This approval will enable DoD customers to connect their BlackBerry Z10 or BlackBerry Q10 smartphones to DoD networks and securely access assets from work, while enjoying the wealth of consumer-oriented functionality that BlackBerry 10 brings to market."
