WatchDox by BlackBerry Deepens Secure Collaboration Capabilities Across Mobile Platforms

WATERLOO, ONTARIO--(Marketwired - Aug. 26, 2015) - BlackBerry Limited (NASDAQ:BBRY) (TSX:BB), a global leader in secure mobile communications, today unveiled updates to WatchDox(R) by BlackBerry(R), including a new application for BlackBerry(R) 10 devices and additional multi-OS integration.

WatchDox by BlackBerry is a secure enterprise file sharing and mobile content management solution. It increases productivity and collaboration by enabling users to connect to files from any PC, tablet or smartphone. Organizations remain in full control of corporate content, even after files are downloaded and shared with third parties. WatchDox by BlackBerry was recently named a "Visionary" in the Gartner "Magic Quadrant for Enterprise File Synchronization and Sharing"(1) for the second consecutive year.

The new WatchDox by BlackBerry application for BlackBerry 10 smartphones, including the BlackBerry(R) Classic and BlackBerry(R) Passport, provides secure anytime online access to content, with synchronization across mobile, desktop and web environments. Users have the ability to browse, access, search and view Microsoft(R) Office, PDF and image files from Windows(R) File Share and Microsoft SharePoint(R). They can securely share links to content with colleagues as well as third party collaborators, enhancing productivity without putting corporate data at risk.

For enterprises with stringent security demands, all content viewed with WatchDox by BlackBerry on a BlackBerry 10 device can be audited to meet compliance requirements. Document encryption is delivered through digital rights management (DRM) policies that are applied to all files, which can only be opened in the WatchDox by BlackBerry application to ensure complete data protection.

"Organizations want to empower their workforce to collaborate and make it easier for them to be productive as the work environment blends between mobile and desktop," said Billy Ho, Executive Vice President, Enterprise Products and Value Added Solutions, BlackBerry. "We believe that WatchDox by BlackBerry is the ideal solution to meet this demand, and the new application for BlackBerry 10 delivers these benefits to customers through essential

mobile content management capabilities. The app is a great complement to our existing iOS and Android mobile offerings and web and desktop interfaces."

WatchDox by BlackBerry has also expanded support to devices with Samsung KNOX(TM), Android for Work(TM) and Secure Work Space for iOS(R) and Android(TM). By adding workspace functionality, the WatchDox by BlackBerry app is completely separate from personal content, creating another layer of security and privacy. The update also integrates mobile productivity tools for users to access, create, edit, annotate, search, stream and share files, as well as performance enhancements that make it easier for users to work with large files.

Additionally, WatchDox by BlackBerry now includes Enterprise Identity by BlackBerry integration, allowing users to access the app from all entry points, including mobile devices, PCs and the web, with seamless single sign-on authentication.
