Does Mobile App Management Service keep data secure?

[Sashapro]

I was looking at software solutions so that my employees can access corporate data on their mobile devices. I've been looking at a few enterprise software options (Vmware, AirWatch, etc.) I looked at a company called Workspot. They have a graphic that shows how their applications fit into a data infrastructure. Can someone explain what this means: 100% Cloud Architecture; Leverages Existing Infrastructure
