sophos agent is not updated

Hello, Shay Hanya,

We appreciate your reaching out to the Sophos Community Forum.

You could try to re-register the agent after turning off tamper protection.

• In Sophos Central, go to Devices.
• Click your concerned endpoint/server.
• On the SUMMARY page, scroll down, then click View password details under Tamper Protection.
• Note the password when you select the Show Password box under Tamper Protection Password Details.
• Sign in to your concerned Windows endpoint.
• Double-click the Sophos Endpoint on the Taskbar.
• Click Admin, sign in, and enter the password you noted earlier.
• Click the Admin sign-in button.
• Select Settings from the top menu.
• Tick the box near the top for Override Sophos Central Policy for up to 4 hours.
• Move the slider of Tamper Protection to the left.
• After Disabling the Tamper protection from the sophos agent,
• Download the new setup file from Sophos Central.
• Open the command prompt as an administrator and type cd <location of the SophosSetup.exe>
• Use the "SophosSetup.exe --registeronly" (without quotes) command to re-register the product on individual devices.
• Please check it in Sophos Central; the devices will get updated.

If the issue persists, I suggest you reinstall the sophos on the device. To uninstall sophos from the device, you can use the sophos ZAP tool.
