BBM Protected offers secure IM chats for iOS, BlackBerry and Android users in the enterprise
BBM Protected had been available for BlackBerry handsets only until now. The service will allow BBM Protected customers to have secure chats with non-BlackBerry Protected workers at other companies, or with customers. If you are a BBM Protected subscriber and want to IM someone without the service, all the latter has to do is download and install the free version of BBM for his BlackBerry, iOS, or Android phone.
BBM Protected is available for BES users and while it does require a subscription, BlackBerry is offering a 30-day free trial. If you are concerned about third parties getting in the middle of your intra-corporate or inter-corporate chats, or want secure communications with customers, BBM Protected sounds like the answer.
