BlackBerry on Monday began the rollout of its first eBBM suite product, which tailors its BBM instant messaging service to enterprise users. Monday marked the debut of BBM Protected, FIPS 140-2 cryptographic library-enabled messaging, between users within the same enterprise, or between organizations who also use BBM Protected, for secure and confidential communications. Who cares about this? Specifically, companies or organizations working in regulated environments, like defense contractors, for instance. In other words, this is BlackBerry trying to shore up its beachhead, and appeal to the big governmental customers (and others including law firms that work in regulated environments) who have continued to form the bedrock of its customer base even as consumers fly to other platforms including Android and iOS.
