SentinelOne Review 2026 - Autonomous AI EDR

概要

SentinelOne is a fully autonomous endpoint protection platform that uses AI to prevent, detect, and respond to threats in real-time without human intervention. Its behavioral AI engine can identify and stop attacks at machine speed.

Purple AI, launched in 2023, brings generative AI to security operations. It allows analysts to hunt for threats, investigate incidents, and take action using natural language queries—dramatically reducing mean time to respond.

A unique differentiator is SentinelOne's ransomware rollback capability, which can automatically restore encrypted files to their pre-attack state, providing a safety net against ransomware attacks.
