The security industry spent the last decade solving detection. Endpoint. Cloud Workloads. Identities. AI. We built better models. We moved beyond signatures. We reduced false positives. We got the alert into the right queue. Then, we discovered the harder problem had been waiting behind it.
The constraint in every SOC today is not detection. It’s investigation capacity. Security teams are generating more critical alerts than any staffing plan can possibly accommodate. The queue grows. Triage waits on analyst availability. Coverage drops on nights, weekends, and surges, exactly when adversaries know to move.
Frontier AI is about to make this exponentially worse. The same models reshaping every industry are being weaponized to chain hidden gaps and vulnerabilities, accelerate attacks, and compress attacker timelines. Investigation cannot stay a human-paced or human-scaled activity. If it does, defenders lose. We built Purple AI to change that.
Every Alert. Investigated. Now.
Starting today, we’re opening up Purple AI Agentic Investigation to all new and existing SentinelOne® EDR customers. In the Singularity
console. Activated with a single click.
The moment a new EDR alert is flagged Critical and Malicious, Purple AI acts, using flags you can trust. It is the output of over a decade of AI and ML models running natively at the edge, from behavioral analysis to real-time threat intelligence. Purple AI investigates signal vs. noise.
It collects evidence. It correlates telemetry across endpoint, identity, cloud, and third-party data. It builds the attack timeline and delivers a verdict: True Positive, False Positive, or Unknown. The complete evidence chain arrives with it before an analyst opens the console. We call it ‘zero-click’ investigation: Automated trigger, zero wait, coverage gaps closed.
Open the Alerts view, and you see it live: Purple AI retrieving context, running threat hunts, querying host telemetry, building the investigation in real time. Then, the verdict lands, supported and traceable, ready for a decision. This is investigation at machine speed. Continuous. At scale. Integrated into existing workflows.
The Native Platform Advantage
Purple AI investigates at this depth because it operates natively on the Singularity Platform. Zero integrations required. Where your team already works. Where your security data already lives.
Bolt-on AI tools layered onto other platforms start from a disadvantaged position. They require connectors, data mapping, and integrations before they can reason. Purple AI reasons directly on telemetry already in Singularity: endpoint, identity, cloud, and third-party data in the Singularity Data Lake. Nothing to configure. One click to activate.
The intelligence is distinct. Purple AI takes a multi-model approach that keeps customers at the edge of frontier AI reasoning capability. Models from leading frontier providers like Anthropic (Claude) and OpenAI (GPT) are part of that architecture. So is SentinelOne’s own Ultraviolet family of models, purpose-built on petabytes of real security telemetry and trained for SOC investigation reasoning. Here, frontier AI reasoning combined with Autonomous Security Intelligence.
Autonomy With Accountability
Agentic AI without defined limits and guardrails is a liability. As an AI-first company, we get that. So we built the limits first. Investigations run autonomously. Response stays on your terms. You decide your human-in-the-loop comfort zone.
Every verdict connects to one-click or policy-driven response actions in Singularity, including governed automated execution through Hyperautomation, SentinelOne’s workflow automation layer. Nothing fires outside the guardrails your team defines. Activation is admin-controlled and reversible at any time. Access is role-based. Every verdict carries a complete, auditable evidence chain. We’ve eliminated black-box decisions. Your analysts can see and review every AI step. The agentic SOC keeps humans in control of what happens next, by design.
What Customers Are Doing With It
Purple AI customers are already seeing the shift. Agentic Investigation is built to extend it further.
“By using Purple AI, we’re saving between 40% and 50% of the time to investigate incidents, allowing us to respond much quicker. It gives us readily available information on alerts — which systems, which users, and why they may be malicious,” said Rod Goldsmith, Cybersecurity Leader at YKK Americas.
“Purple AI really increases our efficiency. It allows users to search logs quickly without knowing any query languages and get answers faster, reducing our Mean Time to Respond,” said John McLeod, CISO at NOV Inc.
“SentinelOne helps us with our incident response process tenfold. We have so many options, from automation to using Purple AI, to give my analysts more confidence in their abilities,” said Zack Moody at KYOCERA AVX.
AI designed to give human defenders a decisive operating advantage. The machine removes the ceiling on what humans can cover.
Singularity Credits
Alongside Agentic Investigation, we are introducing Singularity Credits: a new unified currency for AI-powered workflows across the Singularity Platform. AI should be accessible. Utilization should be visible. Spending stays in the hands of those who set the limits. Credits are built around all three.
Every eligible SentinelOne customer gets free access starting this week. No payment method required. After the trial, Credits are available through partners, direct billing, and eCommerce channels. The balance is visible in real time. Built-in spending controls keep consumption bounded.
Agentic SOC, Autonomous SOC, AI SOC, ISOC: Call it what you want. Just don’t call it a roadmap item.
What we are delivering today is real, accessible and, for the next couple of months, complimentary. It is the agentic SOC in operation. GA, now. Critical alerts automatically investigated. Verdicts autonomously reached. Workflows automatically triggered. Governed authorization. Responses that execute within the policies your team controls and human-in-the-loop gates that your team decides.
The industry has called this many things: The Autonomous SOC, the Agentic SOC, the AI SOC. Gartner now has a name for this model: the Integrated Security Operations Center. Modern threat detection, investigation, and response as a single, continuous, AI-driven loop vs. the historic siloed functions and tool sprawl. More than solving alert fatigue, the new model has the potential to solve the investigation capacity gap and shrink MTTR to a scale and speed that cybersecurity will require in the frontier AI era. At SentinelOne, we have been building for this moment for years.
Investigation capacity should never again be the reason a critical alert goes unexamined. Frontier AI belongs where the data and the analysts already are: In the console, in the workflow, governed by the human customer. We put it there.
