The audit layer for autonomous AI.
Fenz sits beside your agents in every environment — dev, staging, production — continuously auditing behavior, flagging risk, and producing the forensic record your compliance and security teams need.
What we audit.
We audit how autonomous AI agents actually behave — not just what they output. Five behavioral surfaces where real risk lives.
Goal Control
Whether agents stay aligned when tasks shift, context conflicts, or authorization is incomplete.
→Permission Boundaries
Whether agents call unauthorized tools, access restricted data, or bypass human approval.
→Execution Integrity
Whether agents fabricate completion, skip required steps, or keep acting in unsafe states.
→Memory & Context Poisoning
Whether agents get steered by malicious instructions, fake policies, or poisoned memory.
→Compliance Mapping
Whether agent behavior violates internal policy, customer rules, or regulatory requirements.
→Five engines. One forensic record.
Specialized analyzers that audit autonomous AI agents across every dimension of behavior — running in parallel, producing unified evidence.
Trajectory Auditor
Traces agent decision paths from input to output, flagging deviations from approved trajectories.
Permission Boundary Monitor
Continuously validates that agent actions stay within their granted permission scope.
Tool Misuse Detector
Analyzes tool calls and API interactions for unauthorized, excessive, or anomalous usage.
Policy Trace Engine
Maps every agent action against compliance policies and regulatory requirements.
Forensic Replay Engine
Reconstructs and replays agent sessions step-by-step for investigation and evidence.
Unified Verdict
Every engine feeds a single deployment verdict: deploy / remediate / block — with evidence attached.
Proof, not vibes.
Every finding lands as a replayable, timestamped event — tool call, permission check, context mutation, approval gate. Hand it to security. Hand it to legal. Hand it to a regulator.
When an agent fails, you get exactly what happened, in what order, why, and what to change.
Audit one agent.
