Create SIEM in Azure Cloud

The Sentinel All in One deployment option presents a distinct array of functionalities, encompassing the ability to configure workspace retention, daily caps, and commitment tiers as needed. It further facilitates the implementation of user and entity behavior analytics, with a focus on pertinent identities, aimed at the detection and mitigation of advanced threats.

It essentially AI built in Microsoft Sentinel. Furthermore, this deployment option provides health diagnostics for analytics rules, data connectors, and automation rules, thereby guaranteeing the effective operation of the Azure Sentinel Service.
