As AI agents move from pilot programs to production workloads, security teams must detect autonomous systems that access sensitive data, call APIs, and take actions across enterprise environments, often without centralized oversight. According to the 2026 Cost of Insider Risks Global Report, nearly half of organizations report minimal to no visibility into AI agent activity and 44% of organizations believe malicious use of AI agents will significantly or moderately increase data theft risk, while only 19% classify AI agents as equivalent to human insiders.
What to look for in AI security platforms to detect AI agents
Agent identity and behavioral baselining
Any platform that will be effective must treat AI agents as first-class identities, like any other user. This includes behavioral baselines that capture what “normal” looks like for each agent’s tool calls, data access patterns, and workflow sequences. Without this foundation, distinguishing a compromised agent from a productive one becomes guesswork.
Data lineage and context across AI workflows
Detecting that an agent accessed a file is not enough. Platforms should trace data from its origin through every transformation and destination, revealing whether a prompt includes text derived from a confidential source or whether an agent’s output contains sensitive intellectual property. This lineage-based context separates actionable detection from noise.
Runtime monitoring and drift detection
AI agents are non-deterministic. Small changes in prompts or context can produce different tool-call sequences, making static rules unreliable. Effective platforms apply continuous runtime monitoring, inspecting prompts, tool calls, outputs, and cross-agent interactions in real time, and use drift detection to flag when an agent’s behavior shifts outside its established baseline. NIST’s AI Risk Management Framework notes that models can degrade in security posture by up to 40% within six months if left unmonitored.
Coverage across endpoints, SaaS, and agentic workflows
Agents operate across browsers, cloud applications, CI/CD pipelines, and internal infrastructure. A platform that monitors only one channel leaves blind spots. Look for coverage that spans browsers and non-browser utilities, SaaS and cloud applications, email, and IDEs, including agentic browsers and autonomous workflow engines.
Key capabilities of top AI security solutions
Behavioral analytics that extend to non-human actors
Platforms that lead this category extend the same behavioral baselining, anomaly detection, and contextual analysis used for human insider risk to every autonomous agent in the environment.
Proactive detection of shadow AI and unauthorized agents
Effective platforms discover agents that bypass formal vetting and are deployed by individual teams using diverse frameworks, connecting to sensitive APIs without security oversight. Without shadow AI discovery capability, detection only covers the agents you already know about.
End-to-end data lineage across AI workflows
Platforms that track data from origin through every AI interaction provide the forensic context investigators need to determine impact and intent. When an agent exfiltrates data, lineage reveals exactly what was taken, where it originated, and how it was transformed, turning a vague alert into an actionable investigation. DTEX’s approach to closing the trust-risk loop with file lineage shows how this capability changes data loss prevention in the AI era.
The DTEX perspective
AI agents are a new class of insider, autonomous actors with real credentials, permissions, and operational impact. DTEX approaches this challenge the same way it has advanced insider risk management for human actors, by understanding behavior in context, detecting meaningful deviations early, and enabling proportionate response without sacrificing privacy or workforce trust.
The DTEX Platform extends behavioral intelligence to AI Risk Management and AI agents, agentic browsers, and autonomous workflows, providing continuous monitoring, similar to what organizations rely on for human insider risk. The cost of containing threats rises dramatically with every day of undetected risk. Detecting AI agents early and monitoring activity, before they drift, are compromised, or exfiltrate sensitive data, is necessary for proactive insider risk management.
Conclusion
AI agents are already embedded in enterprise workflows, and the gap between agent deployment and agent security is widening. Organizations that treat AI agents as first-class identities, with dedicated behavioral baselines, data lineage, and continuous runtime monitoring, will detect risk earlier and contain it faster. Those who wait will face escalating incidents, regulatory exposure, and investigation backlogs that compound with every unmonitored agent.
DTEX extends its insider risk management and user and entity behavior analytics (UEBA) capabilities to non-human AI agents. The platform baselines behavior for both human users and agents, detecting anomalies such as first-time access patterns, unusual tool invocations, privilege drift, and data movement that deviates from established norms. DTEX’s AI security capabilities provide visibility into shadow AI usage and agentic workflows, connecting data lineage to risk-adaptive controls that prevent sensitive data from reaching unauthorized AI tools. DTEX links behavioral signals to intent, context, and business impact across endpoints, cloud, and SaaS environments.

Frequently Asked Questions
An AI agent is an autonomous or semi-autonomous system that can authenticate into enterprise applications, access data, call APIs, invoke tools, and take actions with limited human intervention. Unlike static AI models, agents plan and execute multi-step workflows, making them productivity tools and a new attack surface that requires dedicated detection and governance.
AI agents operate with real credentials and permissions inside enterprise environments. When an agent is compromised, misconfigured, or granted excessive privileges, it can exfiltrate data, escalate access, or perform unauthorized actions, all through legitimate pathways that traditional perimeter defenses may not flag. This mirrors the behavioral pattern of human insider threats.
Traditional DLP relies on content inspection and static rules, which are often insufficient for detecting AI agent behavior. Agents operate through APIs, tool calls, and automated workflows that may not trigger conventional DLP policies. Platforms that combine behavioral baselining, data lineage, and runtime monitoring provide stronger detection for agentic activity.
Behavioral analytics establishes a baseline of normal activity for each agent, including which tools it calls, what data it accesses, and how it interacts with other systems. When an agent deviates from this baseline, accessing unfamiliar data sources, invoking unusual APIs, or operating outside expected hours, the anomaly triggers an alert that analysts can investigate with full context.
NIST’s AI Risk Management Framework and OWASP’s Top 10 for Large Language Model Applications are the primary frameworks. NIST emphasizes adversarial testing, continuous monitoring, and risk management across the AI lifecycle. OWASP identifies prompt injection, excessive agency, and insecure tool design as top risks for AI-powered applications and agents.
Begin by discovering every AI agent operating in your environment, including shadow deployments. Assign each agent a distinct identity with least-privilege permissions and per-agent logging. Implement continuous behavioral monitoring to detect drift and anomalies. Integrate agent monitoring into incident response workflows to ensure security teams can investigate and respond at the speed agents operate.
