Apple has long echoed this line (part of the reason their purchasing of fleetsmith, not jamf, is surprising).
A sampling of MDMs that large companies you've heard of use:
- vmware workspace one
- bare metal micromdm
- simplemdm
- fleetsmith
- kandji
- jamf
My perspective comes from talking to anyone on the Apple Business team at the San Francisco union square location, and also reps from apple's general business support line.
There are definitely a ton of other MDM solutions, but none that I've heard mentioned so frequently by apple employees as JamF.
