BlackBerry’s deal to acquire Secusmart, a German security vendor known for its voice encryption technology, was recently approved by the German government. Secusmart’s tech will offer BlackBerry users the ability to encrypt voice and data communication. Given that Secusmart is a company used by the German government, the deal went through a careful assessment process. BlackBerry first announced its plan to purchase the company in July and was only recently granted approval to move forward.

“The product was launched in March last year and encrypts both phone calls and data communications,” reports Computerworld.

“It uses a microSD card for storing encrypted documents, and a smartcard chip that performs the encryption. The new BlackBerry Passport handset was added to the list of compatible products this month.”

The voice and data encryption is also available as an app called Secure Call, which is compatible with other operating systems including iOS and Android.

Computerworld notes that BlackBerry recently “joined forces with Samsung Electronics to integrate BES (BlackBerry Enterprise Server) 12 with Galaxy smartphones and tablets.”
