Sophos Endpoint Defence Service High CPU + Unable to update

Hi everyone,

I received a ticket from a user reporting a decrease in the performance of his PC. Checking in task manager I found out that the “Sophos Endpoint Defence Service” is constantly using about 20% of CPU.

Searching for troubleshooting I found out that the “Endpoint Agent” client has not updated in the last month and the button for manually update doesn’t work (the latest updates date back to 03/12/2024 and today that I’m writing this post is 08/01/2025).

After that I tried to uninstall the client witch Sophos Central (everything is working, I have access to the central, the password with this client is working and gave me admin access) but I can’t disable the Tamper Protection because I can’t select the “Override Sophos Central Policy for up to 4 hours to troubleshoot”.

On the central side, except for the “last Sophos Central activity” everything is installed and working fine.

What should I do? Are these two problematics related somehow?

Windows 10 Pro          19045

Core Agent                  2024.2.4.1.0

Sophos Intercept X      2024.2.4.1.0

 

Thank you in advance,

Giorgio
