The tag settings will appear under Entity tags.

To set each type of tag, follow the instructions below.

Sensitive tags

You can also manually tag users, devices, or groups as sensitive.

  1. Select Sensitive. You will then see the existing sensitive Users, Devices, and Groups.

    The Devices tab in the Sensitive entities menu item

  2. Under each category, select Tag... to tag that type of entity. For example, under Groups, select Tag groups. A pane will open with the groups you can select to tag. To search for a group, enter its name in the search box.
