Autonomous AI-powered endpoint security — detect, respond, and remediate at machine speed
SentinelOne's Singularity platform is the AI-driven endpoint security platform that can detect and autonomously respond to threats without requiring a human analyst. Where CrowdStrike Falcon generates high-fidelity alerts that analysts investigate, SentinelOne's Purple AI goes a step further — it doesn't just surface the threat, it automatically kills the process, quarantines the device, and rolls back file system changes caused by ransomware without IT involvement. For organizations that can't staff a 24/7 SOC, SentinelOne's autonomous response capability is the most compelling argument in endpoint security.
SentinelOne Singularity is an AI-powered extended detection and response (XDR) platform consolidating endpoint security (EPP + EDR), cloud security (CNAPP), identity threat detection, and network discovery into a single agent and platform. The Singularity agent uses behavioral AI models that run locally on the endpoint — detecting and responding to threats even when the device is offline, without requiring cloud connectivity to make decisions. Storyline technology automatically correlates all related process events into complete attack narratives, dramatically reducing analyst investigation time. Purple AI is SentinelOne's generative AI security analyst layer — enabling natural language threat hunting, alert triage, and automated remediation workflows.
Deployment model: SaaS platform with lightweight endpoint agent (Windows, macOS, Linux, cloud workloads). Pricing model: Per endpoint per year subscription. Typical price range: $45–$79/endpoint/year (Core to Enterprise); volume discounts at 500+ endpoints.

AI makes real-time decisions to kill malicious processes, quarantine endpoints, and roll back file system changes — responding to ransomware in milliseconds without human intervention.
Automatically correlates all process events, file changes, network connections, and registry modifications into a complete attack story — analysts see the full attack in one view.
Natural language interface for threat hunting, alert investigation, and security question answering — 'Show me all endpoints that communicated with this IP in the last 30 days' in plain English.
Behavioral AI models run entirely on-device — SentinelOne detects and responds to threats even on air-gapped or offline endpoints without cloud connectivity.
Patent-pending technology reverses file system changes made by ransomware — restore encrypted files to pre-attack state with a single click without requiring backup restoration.
Extends endpoint protection to cloud workloads, containers, and Kubernetes — consistent AI detection and response across on-premises and cloud infrastructure.
| Alternative | How it compares |
|---|---|
| CrowdStrike Falcon | CrowdStrike has larger threat intelligence network; SentinelOne leads in autonomous response and offline detection capability |
| Microsoft Defender for Endpoint | Defender is included in M365 licensing; SentinelOne provides deeper behavioral AI detection and autonomous response that Defender doesn't match |
| Palo Alto Cortex XDR | Cortex XDR has broader platform integration; SentinelOne leads on autonomous response speed and Purple AI generative analyst capability |
