Cloud SIEM

“Azure Sentinel works

seamlessly with Office 365

and other Azure services and

security tools. Compared to

other SIEMS I have used, it’s

much easier to connect our

data sources to Azure

Sentinel. There are built-in

connectors not just for

Microsoft but also for other

major security vendors.”
