CloudAI for User and Entity Behavior Analytics (UEBA) is a statistical anomaly detection engine, designed to complement the existing UEBA capabilities and integrate with the KB content in the LogRhythm SIEM. CloudAI provides visibility into insider threats, compromised accounts, and privilege abuse—here, categorized as anomalies.The anomaly scores are not designed to be responded to as alarms, but rather provide low volume, high quality threat hunting leads for your analysts, and additional context into the SIEM for use in correlation, dashboards, and workflows. It compares user or entity activity in a recent 24-hour period, called the Scored Period, to a 29-day baseline, called the Baseline Period.

CloudAI is designed to be intuitive and simple to use, which means there is no end-user configuration required to install or use it. CloudAI components are installed with the Data Indexer (DX) during a LogRhythm Enterprise installation, and LogRhythm Support performs all necessary configuration for data collection at the time you purchase a license; until then, the services installed with the DX are disabled.

Users access CloudAI through linked data in the LogRhythm Web Console. The CloudAI web interface includes the following features:
