Yes, if you are a BBM Enterprise user in BlackBerry 10, you should go to BlackBerry World and update the app now. This update appears to be bug fixes with no known new features, so grab the latest update to have an app that works better.
If you still have to ask what the difference is between standard BBM on BlackBerry 10, Consumer BBM on Android and iOS, and BBM Enterprise, Enterprise offers a more secure version designed for enterprise level customers. The BBM Enterprise application utilizes with FIPS140-2 cryptography and of course a higher level of encryption that increases when using BlackBerry UEM.
Another thing that distinguishes BBM Enterprise is that BlackBerry does not store the encryption keys nor the servers. In fact, every message is sent with a different random key, unlike other solutions that maintain the keys. Of course every user has a unique, non-random key.
Enterprise customers using BB10 BBM, it’s time to update your BBM.
