SentinelOne experienced a six-hour console outage on May 29 that left commercial customers unable to monitor or manage their cybersecurity systems. While endpoint protection remained active, managed detection and response services lost visibility during the incident. The company provided minimal communication during the outage, frustrating customers who compared it to the CrowdStrike incident. SentinelOne stated it was not a security incident but has not released a detailed root cause analysis. The outage occurred shortly after the company reported strong Q1 earnings but lowered future revenue guidance.
