My company uses them. Their MDM and SSO is actually not that bad, and it's much cheaper than jamf.
Buttt... Their support sucks, and their integration engineer was quite useless, and I had to figure almost everything out myself. and their public slack they don't even pay, so you don't get to see support history. (At least there is Macadmins slack)
Hey crawsome, we’d like to talk more about your feedback if you’re open to it. You can email or DM me on the JumpCloud slack, whichever you prefer. Our head of customer success would like to hear more from you.
