SentinelOne AI

SentinelOne is an enterprise cybersecurity platform known for AI-driven autonomous endpoint detection and response (EDR) that detects and responds to threats without requiring human analyst intervention for every alert. Purple AI, SentinelOne's natural language threat intelligence layer, allows security analysts to query threat data, investigate incidents, and perform threat hunting using conversational natural language rather than complex query languages.

The Singularity platform extends EDR to Extended Detection and Response (XDR) — correlating threat signals across endpoints, cloud environments, identity, and network to detect attack sequences that span multiple systems. AI correlation identifies attack patterns that isolated endpoint detections would miss.

The Storyline feature is SentinelOne's distinctive capability — it automatically maps the full attack story from initial compromise through lateral movement to impact, connecting every malicious event into a visual narrative that analysts can review rather than piecing together individual alerts. This attack storyline dramatically reduces investigation time compared to manual alert triage.

Purple AI allows analysts to ask questions in plain English — 'show me all lateral movement in the last 24 hours', 'which endpoints communicated with this suspicious IP?' — without writing Splunk queries or custom scripts. This democratises advanced threat hunting beyond analysts with deep query expertise.
