SentinelOne

SentinelOne is an American cybersecurity company that builds the AI-powered Singularity Platform, autonomous software that detects, hunts, and responds to attacks across endpoints, cloud, identity, and data in real time. Founded in 2013 and headquartered in Mountain View, California, it pioneered machine-learning-driven endpoint protection that works without human intervention and now competes head-to-head with CrowdStrike and Microsoft in the enterprise security market. After the largest cybersecurity IPO in history in 2021, the company crossed $1 billion in annual recurring revenue in 2025.
