Hi Silky,
Thankyou for your response.
So what I seem to understand is that in Sync mode only the data collection is done on the plugin end and the rule application is done on the GRC end whereas in Async both of these things are done on the plugin end.
Also, according to this there is no need of creating a reverse connector from the plugin to the GRC box in case of Sync but is required for Async ??
Thanks & Regards,
