Forbid admin to see devices and accounts of other admin accounts

Is it possible, for example, that I have five different companies and I want them to monitor their devices via one server, but that the admins can only see the devices of their company and not of other companies?

Not possible. What you're probably looking for in the manager role instead of admin.

Ah ok, do admin create managers account and they can add users and devices but other managers can not see their accounts or devices ?

Yes.

Thank you .
