We differentiate between two categories of IT devices: Either it is a managed device or it is an unmanaged device.
Managed devices are those that are installed and maintained by us and where the user doesn't have an administrative account. Mostly desktop computers (Linux or Windows) fall into this category, but in some cases it used for notebooks as well.
Unmanaged devices are for example all macOS devices and most of our notebooks! These devices have to be maintained by their respective users, we only provide a limited set of services, see below.
