TL;DR: AI agent evaluation is moving from niche testing to a broader governance requirement as the market is projected to grow from $0.55 billion in 2025 to $2.05 billion by 2030, according to Openlayer. The core issue is not output quality alone but whether teams can trace tool use, session state, and policy violations before agents reach production.

Questions worth separating out
Q: How should security teams evaluate AI agent trust before production use?
A: Security teams should evaluate AI agent trust by combining identity posture, intended access, delegation paths, and governance metadata in one approval decision.
Q: Why do AI agents create more identity risk than traditional LLM applications?
A: AI agents create more identity risk because they can persist state, choose tools, and carry out actions over time.
Q: What do organisations get wrong about AI monitoring?
A: Many teams monitor uptime and API health but ignore behavioural drift, repeated output anomalies, and subtle steering over time.
Practitioner guidance
- Implement session-level tracing for all production agents Capture prompts, tool calls, retries, branching logic, and state changes so investigators can reconstruct how an agent reached a decision.
- Enforce runtime policy at the tool boundary Block prompt injection, sensitive-data leakage, and unauthorised API use before the agent completes the action.
- Map agent tests to governance evidence Tie CI/CD evaluations, runtime alerts, and exception handling to the governance frameworks your organisation reports against.
What's in the full article
Openlayer's full article covers the operational detail this post intentionally leaves for the source:
- 100+ prebuilt tests across text, vision, tabular, audio, and agent workflows for teams that need implementation detail.
- CI/CD blocking logic and workflow integration examples for committing evaluation checks into delivery pipelines.
- Runtime guardrail descriptions for prompt injection and PII leakage prevention at execution time.
- Framework mapping detail for EU AI Act, NIST RMF, ISO 42001, OWASP, and LGPD evidence workflows.

AI agent evaluation is becoming identity governance by another name. Once an agent can choose tools, maintain state, and act across sessions, it behaves like a non-human identity that needs explicit runtime boundaries. Traditional IAM controls were built for stable accounts and review cycles, not for systems whose effective privileges change from one task to the next. Practitioners should treat agent evaluation as part of access governance, not a separate testing discipline.
A question worth separating out:
Q: Who should be accountable when an AI agent causes a security incident?
A: Accountability should sit with the human owner, platform team, or business function that granted and operated the agent. The identity may act independently, but governance cannot detach responsibility from the delegation chain. Programs should define ownership, escalation, and remediation paths before deployment so responsibility is clear when the agent's behaviour changes.
