In another nod to BlackBerry security, the UK government via the Communications and Electronics Security Group (CESG) has released updated security guidelines for government agencies and various other secure organizations that wish to use BlackBerry 10 devices. The guidelines are designed to help government and corporate users set up devices it deems secure to offer the best balance between work and personal use.

The new guidelines, End User Devices Security Guidance: BlackBerry 10.3, is an update of CESG's previous BlackBerry guidelines at OFFICIAL, for OS 10.2. To test OS 10.3's security features, the group used a BlackBerry Classic running BlackBerry OS 10.3.1 and managed with BlackBerry Enterprise Service 12 (BES 12).

As BlackBerry rightfully noted on their post announcing the updated guidelines, BlackBerry smartphones were the first to be considered secure enough for use by UK government employees and this guidance validates the efforts of the BlackBerry Security Certifications team as they continually improve security within BlackBerry products.
