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.1.2.840.1136126.96.36.199.6] /* exists */ and certificate leaf[field.1.2.840.1136188.8.131.52.13] /* 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 a Proxy Configuration for an MDM other than JAMF? I haven't been able to configure this correctly for Big Sur, if anyone has the .plist that would be greatly appreciated.Kind regards,
Could you elaborate on which MDM solution you're using to deploy this out?
I am using JumpCloud, I have the PPPC working, the Kernel System Extensions as well as the System Extensions, I just can't seem to get the Web Content Filter (proxy) working.Kind regards,
When looking into the available documentation from JumpCloud regarding approval of Network Filtering, I don’t see references specifying that this is possible.
I suspect this will be done under the "system extensions" section. However, other mdm's have additional settings to specify that the configuration will apply to a Network Filter as opposed to a system/kernel extension where Jump Cloud does not.
I've reached out to the Jump Cloud support team to inquire further, but I suggest you do the same as they may be quicker to respond.
