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.
According to the company's public disclosures, SentinelOne protects organizations including 4 of the Fortune 10 and serves thousands of customers worldwide, with FedRAMP High authorization for U.S. federal use. Based on our analysis of 870+ AI tools, SentinelOne sits in the top tier of cybersecurity platforms alongside CrowdStrike Falcon, Microsoft Defender for Endpoint, and Palo Alto Cortex XDR. Compared to those competitors, SentinelOne differentiates through fully on-agent AI (allowing offline protection), one-click rollback for ransomware-encrypted files on Windows, and a flexible Security Data Lake that doesn't lock customers into a single vendor's logging schema.

Combines static AI to block known and unknown malware pre-execution with behavioral AI to detect suspicious runtime behavior. Both engines run locally on the endpoint, so protection remains intact when devices are offline or the cloud connection is severed by an attacker.
Storyline groups every related process, file, network, and user event into a single attack story with a unique ID. This eliminates the manual stitching analysts traditionally do across thousands of EDR alerts and gives a complete root-cause timeline in seconds.
Schema-free, sub-second log analytics platform built on Scalyr technology that ingests from any source — endpoint, cloud, identity, SaaS, network — at petabyte scale. Customers use it to retire Splunk or QRadar with significantly lower ingest costs and longer retention.
Natural-language interface to the Data Lake that translates plain English questions into structured queries, summarizes incidents, and suggests hunting hypotheses. Released in 2024 and expanded through 2025 with autonomous triage and multi-step investigation capabilities.
Patented capability that uses Windows Volume Shadow Copy and SentinelOne's own behavioral tracking to revert files encrypted by ransomware with a single click. This effectively neutralizes ransomware as an extortion vector for impacted Windows endpoints, a feature unique among major EDR vendors.

Through 2025 SentinelOne significantly expanded Purple AI with autonomous triage, multi-step investigation, and natural-language hunting across the Singularity Data Lake. The platform also broadened its Cloud Native Security (CNAPP) coverage and deepened identity threat detection capabilities, with the company positioning the Singularity Platform as a unified replacement for legacy SIEM, EDR, and CNAPP point tools.
