Product & Service delivery to consumer/biz

Not to sure how to frame this but we’re planing to offer our own imp based products and services. We’ve been looking for the layer that sit’s above the e.imp platform that does:

User management
Authentication & Access control
App delivery
Data logging & visualization
e.imp Agents
e.imp Impees

We’ve been looking various solutions out there we can see some providers giving us a bit of what we want. Some seem to be part time projects. Below is list of what we’ve looked so far. Would be interested in folks views and experiences of any of the below.
