Mobile device management

This is the most common form of device management. Check in System Preferences → Profiles. If there is no Profiles button, there are no profiles installed and this option is not in use. If there are profiles present, check the details of the profiles for their capabilities.

Remote management

A precursor to MDM, this is activated in a separate location: System Preferences → Sharing. Remote Management is one of the options and can be deactivated, along with other forms of remote connectivity to various parts of macOS.

Other software

Plenty of other software can be installed on macOS and provide remote access. If you are worried about this sort of access, audit the processes running in Activity Monitor and/or perform a fresh install of macOS.
