We use Sophos with the enterprise console. I made a pkg with Packages that contains the Sophos installer app and the Sophos Installer Components Folder. I then use munkiiport to import the pkg into munki. When installed by munki, the pkg extracts both the folders to /Users/Shared/ and then munki runs a postinstall script :-
<key>postinstall_script</key>
<string>#!/bin/sh
/Users/Shared/sophos_installer/Sophos\ Installer.app/Contents/MacOS/tools/InstallationDeployer --install
rm -R /Users/Shared/sophos_installer
</string>
The components folder has the details of the enterprise server etc.
