• When: Occurred on Thursday; services were restored by 7:41 PM UTC.
• Where: The issues were highlighted on social media and confirmed by the company.
• Why: Early analyses suggest this is not a security breach but possibly rooted in internal service issues.
• How: The outage lasted for approximately six hours, with initial reports linking it to cloud service limitations, as SentinelOne utilizes AWS infrastructure.

Why It Matters:
This incident underscores critical areas of concern for IT professionals:

• Enterprise Security: Continuous protection of endpoints was assured, yet the loss of managed response visibility can jeopardize rapid incident response.
• Cloud Reliability: Dependence on cloud infrastructure necessitates thorough contingency planning, especially for software-as-a-service models.
