Gartner forecasts that 40% of enterprise apps will embed agents by end of 2026, making behavioral monitoring increasingly critical. Organizations like Exabeam, Zenity, and Fiddler are expanding agent monitoring capabilities within existing security infrastructure—but enterprise needs demand more than retrofitted tools. This post is cross-published from agentlair.dev . The Core Problem Enterprise deployments require real-time detection when agents perform unauthorized actions. This demands four operational capabilities: Per-agent behavioral baselines — Individual agent instances need specific, measurable patterns rather than type-level categorization Sequence-level detection — Analyzing tool-call chains rather than individual actions to spot exfiltration attempts hidden in authorized operations Continuous trust scoring — Dynamic assessment that updates with each action rather than static gates Cross-session memory — Behavioral context preserved across container restarts and session boundaries SIEM Limitations…
