Few years ago I noticed BBM Enterprise touts end-to-end encryption pretty strongly in their marketing, without mentioning an up-front caveat. https://www.blackberry.com/us/en/products/bbm-enterprise https://www.blackberry.com/us/en/products/bbm-enterprise Turns out that by default, BBME is not end-to-end. The initial handshake is transparent to Blackberry, and they could use that to decrypt future messages without your knowledge. To enable true end-to-end, you have to opt in to an out of band handshake to start each new conversation, an option you can turn on in their admin console. How many people are actually going to opt in to dealing with a confirmation SMS for every new thread? I reached out to Blackberry at the time to update their literature as it was misleading, but no action was taken by them.
