Series F $1.897B total Founded 2013 Mountain View, California 1285 employees
SentinelOne's Singularity Platform is a unified, AI-driven endpoint security solution that prevents, detects, and autonomously responds to threats across endpoints, IoT devices, and cloud workloads in real-time. The platform uses patented behavioral AI and machine learning to block known and unknown threats without relying on signatures, with autonomous decision-making at the device level rather than requiring cloud decisions. A key differentiator is the one-click instant rollback capability that reverts systems to a safe state before damage occurs. Enterprise customers across all industries rely on SentinelOne to protect trillions of dollars in enterprise value across millions of endpoints.
Problem solved
Organizations struggle to protect diverse endpoint environments against known and unknown threats while managing alert fatigue and requiring human intervention for threat response.
Target customer
Enterprise organizations across all verticals requiring unified endpoint protection, detection, and response capabilities; mid-market to Fortune 500 companies with significant endpoint footprints and advanced security requirements.

Competitors
CrowdStrike Falcon
Broader portfolio with EDR/XDR focus; cloud-first architecture versus SentinelOne's device-first autonomous approach.
Microsoft Defender for Endpoint
Part of Microsoft ecosystem with tighter Windows integration; SentinelOne offers more advanced behavioral AI and cross-platform coverage.
Palo Alto Networks Cortex XDR
Comprehensive XDR platform with broader attack surface coverage; SentinelOne specializes in autonomous endpoint response with faster device-level decisions.
Sophos Intercept X
Strong SMB focus with managed services; SentinelOne targets enterprise scale with autonomous AI-driven response.
Why this matters: SentinelOne represents a significant shift in enterprise security toward autonomous, AI-driven threat response at the device level rather than cloud-dependent decision trees. As a publicly traded company (NYSE: S) with $1.9B+ total funding and aggressive M&A strategy (acquiring Scalyr, Attivo Networks, PingSafe, and Prompt Security), SentinelOne is reshaping the $15B+ endpoint security market by proving autonomous behavioral AI can match or exceed human-driven security operations at enterprise scale.
Best for: Enterprise organizations and mid-market companies needing autonomous, AI-driven endpoint protection that prevents, detects, and responds to threats without human intervention across large heterogeneous endpoint environments.
Use cases
Ransomware Prevention and Autonomous Response
Organizations deploy SentinelOne to autonomously detect and block ransomware attacks including fileless variants before they encrypt data. The behavioral AI engine identifies attack patterns in real-time while the instant rollback capability can revert affected systems to a safe state, reducing recovery time from days to minutes.
Unified Multi-Vector Threat Protection
Large enterprises consolidate endpoint protection, EDR, IoT security, and cloud workload protection into a single Singularity Platform, eliminating tool sprawl and providing unified visibility across all assets. This reduces alert fatigue and security team overhead while improving incident response speed.
Zero-Trust Endpoint Security at Scale
Distributed enterprises implement device-level autonomous decision-making through SentinelOne's single agent, reducing dependency on cloud connectivity and human analysts. The platform protects remote endpoints with consistent security posture regardless of network location, ideal for hybrid and remote-heavy organizations.
Unknown Threat Detection Without Signatures
Security teams use SentinelOne's behavioral AI to catch novel and zero-day attacks that signature-based tools miss. The heuristic model analyzes endpoint behavior patterns to identify anomalies indicative of attack, enabling protection against emerging threats before vendors can release signatures.
Alternatives
CrowdStrike Falcon Broader integrated platform with threat intelligence and identity protection; choose if you need ecosystem integration with Crowdstrike's TIP and other modules.
Microsoft Defender for Endpoint Best for organizations deeply invested in Microsoft ecosystem seeking tight Windows integration and bundled licensing; SentinelOne offers superior cross-platform and autonomous response capabilities.
Palo Alto Networks Cortex XDR Choose if you need broader attack surface coverage including network and cloud; SentinelOne excels specifically in autonomous endpoint response and device-level decision-making.
FAQ
What does SentinelOne do? +
SentinelOne delivers the Singularity Platform, an AI-driven, unified endpoint security solution that prevents, detects, and autonomously responds to threats across endpoints, IoT devices, and cloud workloads. Using patented behavioral AI, the platform blocks known and unknown threats in real-time without relying on signatures, making autonomous security decisions at the device level while providing instant rollback capabilities to revert compromised systems to safe states.
How much does SentinelOne cost? +
SentinelOne uses per-endpoint annual subscription pricing starting at $69.99/endpoint/year for Singularity Core, scaling to $229.99/year for Singularity Commercial with advanced features. Enterprise deployments are custom quote-based. Volume discounts apply at 500+, 1000+, 5000+, and 10000+ endpoints, with multi-year agreements offering 15%+ savings.
