Exporting a list of all incidents from Sentinel
I'm trying to export a csv of all the incidents ever registered in Sentinel in my org. This covers 2+ years of Sentinel usage. I did some digging and it turns out you cannot export data from the Threat Mgmt > Incidents tab. You can however export a table of incidents from Log Analytics by SecurityIncident query (set the time frame to the earliest data possible).
So I did exactly that and set the display count to "max limit". Each time, the query only outputs a list going back 90 days in time. Is there a data retention limit in Log Analytics that doesn't allow you to view or export incidents longer than 90 days?
Is there any other way I can go about exporting ALL incidents registered in Sentinel?
Thanks!
