A device showing as “Not managed” or “Offline” indicates that either the machine is not connected to a Workspace or there is Firewall issue.
This does not affect your protection but only the ability to communicate with your Workspace.
First, make sure to check that no countries are excluded from the geolocation list in the Firewall and add http://cloudbroker.emsisoft.com/, TCP port 61614 out.

If the steps above have no effect on your devices status, please do the following:
Download and run the Workspace installer to connect the unmanaged device to the Workspace by clicking on the “Download and install protection” button from the Workspace panel overview.
Open Emsisoft Anti-Malware application, and click the ‘update’ link in the lower right to update and synchronize with your subscription.

Resetting this view filter will display all devices linked to this workspace irrespective of their status.
