Azure Data Explorer

Azure Data Explorer (ADX) is a fast, fully managed data analytics service from Microsoft designed for real-time analysis of large volumes of streaming data. While primarily a data analytics platform, ADX is increasingly used as a security data pipeline and lake for organizations that want to store, query, and analyze security telemetry at scale with Kusto Query Language (KQL), the same query language used by Microsoft Sentinel.
