1. MobileIron

Squeaking out the top spot in Gartner's Magic Quadrant is Mountain View, Calif.-based MobileIron.

MobileIron provides an EMM solution that is specific to the software and devices of an organization.

The company's MDM features support iOS, Android, Windows Phone, Windows 8 and Mac OS X, while its mobile application management module supports iOS and Android.

The Gartner report credits MobileIron as being the only EMM vendor that offers real-time remote-view capabilities on iOS. Consequently, the Magic Quadrant notes that MobileIron has "more limited Android manufacturer API support than many other leading EMM vendors."
