What’s happening

On a MacOS computer that uses applications such as Virtual Machines, or has other Anti-malware software present, , a Sophos Home alert is received stating This Device is Vulnerable, however, all the protections are enabled in the dashboard.

This issue may happen if the Mac computer has too many applications using virtual slots, thus, there is no slot to add Sophos Home kexts.
This is a macOS limitation regarding virtual devices slots. When the system does not have enough virtual device slots, whichever application loads last will be unable to load its kexts.

Symptoms:
All scenarios as per this article 
have been covered, yet the problem persists.
Furthermore, you see that code “dc008017” is present in the logs, by following these steps: 

Access Spotlight by clicking on the magnifying glass
Type Terminal and hit Enter
Inside the terminal, type:
cd /Library/Logs
(Hit Enter)
zgrep dc008017 SophosDiagnostics*
(Hit Enter)

If no results are shown, then most likely, this is not the issue affecting your system, please refer to the scenarios listed above.  If there is a result, then jump to the Workaround section.

If all fails, despite having followed the common scenarios, you’ll need to remove one (or more) of the applications that are using virtual slots (such as virtual machine software, other antivirus software) , and restart the Mac computer.
Once you have removed the applications and reboot the Mac, if the problem persists, re-install Sophos Home
