Hello @venianakis,
the connector includes engines which are working online, and other which are also working offline. Enclosed some infos which may clarify your question. Offline outlines which engines are working withou any need to be connected to the Backend. Cloud IOCs are working online and offline, as the backend engine processes all the telemetry data 7 days back.
BTW, have seen a small issue about exPrev in the screenshot, as the engine triggers under several conditions.
Greetings,
Thorsten
