While BBM Protected has been keeping enterprise users' chats secure since last year, it only used to work if it's installed on both parties' phones. Now, though, the feature can keep convos secure even if only one of the chatters has it. In fact, the other person doesn't even have to be a BlackBerry user: Protected now works even on iOS and Android devices. Considering you can't exactly force, say, clients to ditch their iPhones, Samsungs and HTCs, among other brands that carry Android, this is definitely good news. Those who absolutely have to chat through secure methods only need to start a Protected convo, and the message above will appear so long as the other person has the BBM app. Hopefully, company execs can stop worrying about employees unknowingly leaking sensitive info by using unprotected apps. Unless, of course, they're the ones being reckless.
