Untethered Labs launched Halberd, the latest device in wearable access control, in December. The product caps off years of research and development by UL staff and follows the success of its predecessor, GateKeeper. Halberd is a Bluetooth proximity–based, access-control device that permits the user to leave his or her computer, with Halberd automatically locking the computer as they depart, and upon return, Halberd restores the screen — all with no constant pins and passwords. The business advantages in convenience, security and productivity are obvious. It saves computer security from breach as soon as a user leaves the immediate area as well as saves any lost work time logging on and off computers. Personal security is also greatly enhanced by the automatic lock and unlock capability based on proximity. Industries such as medicine, law, security, transportation and education will get a competitive advantage, as their competitors waste time, manpower and put themselves at potential of serious and costly data breach.
