What is SentinelOne?

SentinelOne is an AI-powered cybersecurity platform for endpoint, cloud, and identity protection. It uses autonomous threat detection, prevention, and response to help organizations secure their environments.

SentinelOne is an enterprise cybersecurity platform that delivers AI-powered autonomous protection across endpoints, cloud workloads, identities, and data, with pricing structured around its Singularity platform tiers (Core, Control, Complete, Commercial, and Enterprise) typically sold as enterprise contracts. It is built for mid-market and large enterprise security teams, MSSPs, and federal organizations that need unified XDR and SIEM-class visibility without the operational overhead of legacy tools.

Founded in 2013 and publicly listed on NYSE in 2021, SentinelOne (Singularity Platform) combines static and behavioral AI engines to detect malware, ransomware, and fileless attacks, then uses its patented Storyline technology to automatically correlate events into a single attack narrative. The platform extends beyond traditional EDR into Cloud Native Security (CNAPP), Identity Threat Detection and Response (ITDR), and the Singularity Data Lake, which ingests log data from any source for unified threat hunting and analytics. Purple AI, the company's generative AI security analyst released in 2024 and expanded in 2025, lets analysts query telemetry in natural language and generate hunting hypotheses across the data lake.
