Thanks for the tip Garreth, It took me a while to actually find the connector for Sophos as only some are displayed under the appliance yet more can be found when looking at the node directly. Anyway I've attempted to configure it using the Sophos Enterprise 3 connector and changed the name & port of the SQL database to match ours yet i'm not sure if its working or not since i don't seem to have any kind of indication of an increase of events/alerts.
I've tried restarting the connector multiple times, and even restarting the SolarWind service on the Sophos server itself to see if it would do something. So i'm starting to get stuck :/
