Microsoft Sentinel

Microsoft Sentinel is a born-in-the-cloud SIEM that leverages the infinite scale of Azure. In 2026, it is the primary choice for organizations heavily invested in the Microsoft 365 and Azure ecosystem, as it offers free ingestion for several Microsoft data sources. It uses AI to significantly reduce alert fatigue and features a 'Logic Apps' engine for advanced SOAR automation. Sentinel’s deep integration with Microsoft Defender provides a unified threat protection experience from the endpoint to the cloud.
