Computer is at Risk? Red icon showing on Mac OS version of Sophos Home. Web console shows it is secured.

Question

I have Sophos Home installed on my MacBook Pro 2018. MacOS version is 10.14. 
 The Sophos Home icon always turns to red and shows "Computer is at Risk" after several days. On Sophos' web console, I can see my Sophos Home works fine, and my laptop is secured. 
 To turn this off, I have to uninstall and reinstall the software. 
 What is the cause of the issue? Do I have to reinstall the software? 
 Here are some symptoms. 
 Once this happens, on Sophos Home's about window, Version becomes Unknown, and Last Updated shows N/A. The log file in /Library/Logs shows it was updated hours before. 
 
 Click the red icon, all Real-time Protection, Web Protection, Potentially Unwanted App Protection are disabled: 
 
 Click one of the Enables, I am redirected to Sophos Home's web console. However those options are showing enabled:

Removing the device and reinstalling solves the issue, but I just don't want to do this every couple days. 
 Thanks

Hi ygary, 
 Due to a new security mechanism that Apple has released with MacOS 10.13, called Secure Kernel Extension Loading (SKEL), all non-Apple kernel extension (what we use to intercept files, etc) vendors must be manually added to a trusted list (Any user can add this). This allows the kernel extensions to load and is required for Sophos Anti-Virus to function properly. All 3rd party vendors are impacted by this change, and it is not possible to work around this requirement. 
 Can you make sure if the Kext by Sophos is allowed manually?
