I was reading up on iPhone in the enterprise and saw something about Mobile Device Management servers. As far as I can tell, there are a few 3rd party MDM vendors, but Apple
There are a lot of MDM products that serves the iOS device management purpose. There are a lot out there like Airwatch, Mobileiron, Meraki, SimpleMDM etc. I've tried out Hexnode MDM and it is worth checking out.
Hope this helps.
