The support we received from MobileIron is one of the driving factors as to why we chose them. Walter Holda and Andrew Ramsey were very responsive to our requests, questions etc. We have not experienced this same level of support with other MDMs.
MobileIron blows BlackBerry out of the water in all aspects... no competition. MaaS360 is not bad, but it had a few technical limitations at the time that I performed my evaluation, which is why we picked MobileIron. MobilIron's customer support beats everyone else.
MobileIron is well suited for the Air Force because of how well it manages/secures devices for multiple different use cases, by allowing different spaces using different ABM and VPP accounts, while also applying different profiles.
