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.
