BlackBerry Ltd. introduced a tablet computer aimed at government and corporate customers that it says can let users access consumer applications such as YouTube and WhatsApp while keeping confidential work-related information away from spies and crooks.

The SecuTABLET, shown at the CeBIT conference in Hanover, Germany, is based on Samsung Electronics Co.'s Tab S 10.5 and uses International Business Machines Corp. software to wrap applications that hold secrets into a virtual container where they can't be harmed by malware. Germany's computer-security watchdog is certifying the device for classified government communication, BlackBerry's Secusmart unit said on Saturday.

BlackBerry acquired Secusmart last year in an effort to win more business from customers demanding rigorous data security. The Waterloo, Ontario-based company, which sold few of its own 2011 Playbook tablets, is shifting from making hardware to building security components and software into competitors' devices as the frequency of cyber attacks mounts.
