SentinelOne Unveils Detection System as Traditional EDR Tools Struggle with AI Agents

SentinelOne Addresses Critical Gap in AI Agent Security

SentinelOne introduced Singularity Agentic Detection and Response (ADR) at OneCon 2026, targeting a growing vulnerability in enterprise security. The AI security offering addresses what Chief Product Officer Chris Corde describes as a fundamental blind spot: traditional EDR systems cannot adequately monitor AI agents operating within workplace environments. "Because they sit inside these agent platforms, you can't actually see them with traditional EDRs," Corde explained during an interview. "If you're not monitoring that from a security perspective, you're flying blind."1

The challenge extends beyond sophisticated AI applications. Even routine agent activities can trigger actions requiring security oversight, yet conventional endpoint detection and response tools lack the capability to track these behaviors effectively. As more organizations adopt agentic technologies, this visibility gap continues widening, creating substantial risk across AI-driven enterprises.

How Singularity ADR Tackles Unmonitored AI Behavior

Singularity Agentic Detection and Response combines SentinelOne's endpoint protection capabilities with technology acquired from Prompt Security. The integration enables security teams to trace the complete chain from initial prompt through every subsequent action an agent takes. This depth of visibility proves essential for identifying both malicious AI agents and instances where sanctioned agents deviate from intended behavior. "You told an agent to do something, it starts to do things that are not necessarily what you had designed or desired," Corde noted.1

The new offering discovers AI agents across the enterprise, enforces policies governing what agents can access, monitors agentic behavioral monitoring in real-time, and stops unintended or malicious activity immediately. Built directly on the Singularity Platform, it extends protection to AI agents operating on endpoints, cloud workloads, and throughout the broader enterprise infrastructure that already serves over 15,000 SentinelOne customers worldwide.2

Why Traditional EDR Falls Short on Agent Monitoring

Corde emphasized that SentinelOne's approach differs fundamentally from competing solutions attempting to solve AI security through network gateways. Many vendors deploy network appliances at the edge to monitor agent interactions with external LLM models. However, this strategy misses the majority of agent behavior occurring directly on devices. Tools like Claude operate as full virtual machines embedded at the device level with integrated LLM models, rendering network-based monitoring ineffective.

Traditional EDR tools remain particularly blind to agent interactions with file systems and operating systems. Without persistent agents capable of monitoring at the device level, competing solutions cannot observe or block these critical activities. SentinelOne's runtime behavioral detection engine applies the same behavioral analysis used for traditional threats to agent actions, catching and stopping agents that act outside their intended scope.1

From Governance to Real-Time Response

Singularity ADR builds on capabilities SentinelOne introduced in March with Prompt AI Agent Security, which focused on discovering AI agents and governing their connections to tools and data. The new offering advances beyond governance to pair agent oversight with behavioral detection and response across endpoints, cloud workloads, and identities. Security teams gain unified visibility into both what an agent was instructed to do and what actions it actually executed on the system.

The solution enables granular control, allowing teams to stop a single rogue agent mid-action without disrupting the entire workflow. This capability addresses the reality that AI agents now hold real credentials, chain tool calls, and operate independently across modern enterprises. With tools like Claude Code, Cowork, and Codex, every employee effectively manages agents, multiplying the potential attack surface.2

Expanding AI Security Portfolio

Alongside Singularity ADR, SentinelOne unveiled Singularity ASOC, integrating AI investigations and autonomous response with security data management and its AI SIEM offering. The company also launched an AI Security Services partner program designed to help organizations build comprehensive AI security practices. These announcements reflect SentinelOne's broader strategy to defend every surface AI touches, from the models powering intelligence to the agents acting on their behalf.

CEO and co-founder Tomer Weingarten framed the urgency: "Agents hold real credentials and act without waiting for anyone. Singularity ADR brings the runtime protection that already defends tens of millions of endpoints, workloads and identities to the agents doing real work inside the enterprise, so our customers can adopt AI at full speed."2

Singularity Agentic Detection and Response entered early access immediately following its OneCon 2026 introduction, positioning SentinelOne to address the escalating risks as agent adoption accelerates across industries.
