The enterprise security solution seems like competing with Good Technology (it’s name of a company - just acquired by Blackbery).
I remember deploying Good Technologies in the early 2000’s as an alternative push technology for email instead of using Blackberry’s solution. Surprised they are now part of Blackberry as well as that they can contribute 160M in revenue. I remember they got bought by Symbol and later sold off by Motorola when they bought Symbol, thought they would have been gone by now
