SentinelOne Purple AI: Advanced AI-powered endpoint protection platform with automated threat detection, investigation, and response capabilities

SentinelOne Purple AI is the generative AI security analyst built into the SentinelOne Singularity Platform — an enterprise-priced, sales-quoted add-on typically bundled at $20–$35/endpoint/month alongside XDR — designed to accelerate threat hunting, investigation, and response across endpoints, cloud workloads, identities, and data sources. Rather than functioning as a standalone chatbot, Purple AI acts as a co-pilot for security operations teams, translating natural language questions into complex queries, summarizing alerts in plain English, and orchestrating multi-step investigations that would otherwise require deep expertise in query languages such as PowerQuery or KQL. Analysts can simply ask questions like 'show me all suspicious PowerShell activity in the last 24 hours across Windows endpoints' and receive structured, actionable results drawn from the Singularity Data Lake. Purple AI is tightly integrated with SentinelOne's Singularity XDR, Endpoint, Cloud Security, Identity, and Data Lake offerings, which means it can reason over unified, cross-domain telemetry rather than querying siloed data stores individually. This unified architecture enables Purple AI to correlate endpoint detections with cloud workload anomalies, identity-based threats, and ingested third-party logs in a single investigation workflow. The platform's Storyline technology automatically maps process trees, lateral movement, and persistence mechanisms into visual attack narratives, and Purple AI leverages these storylines to generate concise investigation summaries that analysts can share with stakeholders or paste directly into ticketing systems. For organizations building toward an autonomous SOC, Purple AI connects directly to Singularity Hyperautomation, allowing AI-generated triage conclusions to trigger one-click or policy-driven remediation actions — isolating compromised hosts, killing malicious processes, or rolling back unauthorized file changes — without requiring manual intervention at every step. Enterprise data privacy is central to the architecture: each customer's queries and telemetry are processed within tenant boundaries, and SentinelOne has committed to not using customer data to train shared foundation models, a critical requirement for regulated industries such as healthcare, financial services, and government. Purple AI supports configurable data residency across US, EU, and APAC regions, and the underlying Singularity Platform holds SOC 2 Type II, GDPR, and HIPAA compliance certifications. Since its general availability in late 2023, Purple AI has become a key differentiator in SentinelOne's competitive positioning against Microsoft Security Copilot and CrowdStrike Charlotte AI, with the company reporting that Purple AI reduces average investigation time by up to 80% compared to manual query-driven workflows.
