This article covers how to protect your Mac with Sophos Home after installing or upgrading macOS 11 Big Sur.
Post Installation - Allowing the Network Extension
The installation/upgrade process involves 4 steps:
Enabling System Extension
As the update/installation progresses, pop-up notifications will inform you if any extensions need to be Allowed via Security & Privacy. For detailed steps see the Troubleshooting section.
There are 2 extensions involved: SophosWebNetworkExtension and SophosScan.
You can need to check Security and Privacy to ensure there is nothing pending to be allowed:

A message will appear on the top right, informing users to enable notifications. Click on the message and use the slider to turn them on. You may need to perform this twice
Granting Full Disk Access to components
A Welcome to Sophos window will instruct the user to drag-drop extensions into Full Disk Access.
Rebooting the Mac
Once finished following all the steps, restart your Mac to complete the installation process.
"This device is vulnerable"
The computer needs to be restarted to complete the installation. If the system is still vulnerable after a reboot follow the Troubleshooting section.
Network Filtering applications interference
Network filtering applications such as Little Snitch or VPN software running in tandem with Sophos Home or other software with network filtering capabilities, may trigger errors or not work at all. If you experience issues with Sophos Home or another network based program, we recommend either disabling or removing the other program and re-testing functionality.

LaunchPad/Applications folder shows several Sophos Home apps
After Installing/Updating to Sophos Home on Big Sur, you will see 3 Items in the new Launchpad/Applications folder:
- Sophos Home
- Sophos Scan
Big Sur will show all the apps in the new launchpad. There is no action needed, nor will these apps launch the antivirus. To launch Sophos Home, please see Locating Sophos Home in your system
If desired, the apps can be moved to a folder to keep them all under one place: https://support.apple.com/en-in/guide/mac-help/mh35840/mac
