Hi @Georges Hayek ,
Just in case you need to get the top 10 incidents (based on the count of incidents), I leave you the following Kusto query that provides that information:
SecurityIncident
| summarize ["Number of Incidents"] = count(), ["Incidents List"]= make_list(IncidentNumber) by Title, Severity
| top 10 by ['Number of Incidents'] desc
| project-reorder ['Number of Incidents'], Severity, Title
I hope it helps. (If so, don't forget to mark as an answer :))
BR,
George
