We have made this process significantly easier. Our installer download now includes an MDM profile for permissions and a script for use to deploy the endpoint via MDM. Here are our instructions for how to use these. It is written for JAMF Pro, however the MDM profile and script should work in other MDM solutions.
This article describes the steps to configure JAMF to allow configure permissions for Sophos Mac Endpoint on macOS 10.15+
Applies to the following Sophos products and versionsSophos Central Mac Endpoint 10.0.0 and above,Sophos Central Intercept X 10.0.0 and above,Sophos Central Device Encryption 1.5.2 and above,Sophos Anti-Virus for Mac OS X 9.9.7 and above
With macOS 10.13, Apple introduced a new security level that required each 3rd party vendor's kernel extension to be approved. This required Team ID to be allowed, also known as the Apple Developer ID.
With macOS 10.15, Apple added a new default behavior that prevented applications from writing to the disk.
The information below covers both topics:
To alert and inform users, Sophos implement a notification popup. The endpoint will check after each reboot (and continuously every 30 minutes) if the system permissions are compatible.
Note: In Sophos for Mac 9.9.5, a notice is displayed if required permissions are not fully enabled. On October 31st, an issue was found where the notice is triggered if the permissions have been added via an MDM profile, as Apple records these in a different location. Sophos is actively working on updating the detection to correct this.
There are 2 steps required to configure compatibility for macOS 10.15.x (Catalina) and below.Note: One additional step is required if you want to apply the profile to a macOS 11 (Big Sur) device.
identifier SophosMDR and anchor apple generic and certificate 1[field.1.2.840.1136220.127.116.11.6] /* exists */ and certificate leaf[field.1.2.840.113618.104.22.168.13] /* exists */ and certificate leaf[subject.OU] = "2H5GFH3774"
codesign --display -r - <app path from table above>
The same profile can be used, but the option "Approved Kernel Extensions" needs to be selected. If this is not configured yet, select the "open" button at the center to begin the configuration.
During configuration, 3 kernel extensions will need to be added, as well as the Sophos Team ID [2H5GFH3774]
Note: Please ensure that "Allow users to approve kernel extensions" is unchecked.
Referring to the screenshot above, add the following kernel extensions:
Make sure to save your changes.
Note: Apple has added a new, optional, method of setting authorization of applications for Privacy in Big Sur with MDM. This new method replaces an existing true/false option with a string value option instead. Here is the Apple article on it: https://developer.apple.com/documentation/devicemanagement/privacypreferencespolicycontrol/services/identity Allowed is the normal method of setting permissions, however as of Big Sur, Apple allows you to instead use Authorization. Our detection for permissions has been configured for the “Required” property (which isn’t actually required if you have Authorization instead). If you can set your MDM provider to use the Allowed True/False (Boolean) setting, it should work without any issues. To check if this applies to you, open the .mobileconfig file in a text editor and search for Sophos. Check if you see - <key>Allowed</key><True/>, or <key>Authorization</key><String>Allow</string>. If it is Authorization, this applies to you. We do recognize that there is a move to this alternate form, and as such, we have made an improvement, coming out in our 10.1.3 release in July, to detect both versions. Until this releases, we recommend using the Allowed True/False style privacy permission setting for Sophos processes.
The same profile configuration can be used.
Note: Sophos does not guarantee the security of third party applications and they should be used at your own risk.
There is a utility called PPPC Utility on Github which allows you to build a configuration profile for Privacy Preferences. It can be located here: https://github.com/jamf/PPPC-Utility. To use this, follow the guidance on the link, and drag and drop the Sophos items into it.
This profile can then be loaded into JAMF.

How to Configure JAMF Privacy Preferences for 10.15 Compatibility
Special thanks to mscottblake for sharing this!
Within the same Configuration Profile, add a Content Filter payload (this requires Jamf Pro 10.26+) with the following keys and values configured:
Note that the Filter Name can be anything, but it is required.
Once the complete, the payload should look like this:
Is there no progress yet on the issue "where the notice is triggered if the permissions have been added via an MDM profile"? This article hasn't been updated since November, but it's still referenced in KB 134552, updated 24 Mar 2020.
As of now, we need to provide permission as stated above. We will be updating our forums as soon as there is any update on this issue.
There have been no resolutions to this post and we are needing to deploy Catalina soon. What is the status of the Full Disk Access Window issue? This is honestly unacceptable, seeing as this issue has been known about for 6 months now.
This is a new requirement from Apple. Sophos requires this access in order to scan the system. Apple has made it so it must be requested by the user or set in the MDM.
It still doesn't work. Sophos still ask for permission to files, even thought we have made all the PPPC settings. This is version 9.9.8.
It looks like it's not enough with SystemPolicyAllFiles, but they also need SystemPolicySysAdminFiles.
Then we got it working.
