The organization deploying an AI agent remains accountable for what it does and for the evidence it produces. The agent should not be the sole authority on whether its own actions or the controls around it are trustworthy. Assurance requires independent, risk-based review; evidence that reviewers can verify; monitoring in the live environment; and human approval for consequential actions.
What does it mean to attest an AI agent?
An agent may gather records, check settings, or report whether a control appears to be in place. That can help with oversight, but the agent’s account is not independent proof that its evidence is complete, accurate, or unbiased. The practical question is who can examine the agent’s access, methods, outputs, and actions—and require a correction or stop its operation.
This is an accountability question, not one that currently has a single universal agent-certification answer. In a TechRadar Pro Perspectives article published October 1, 2026, Khushboo Kashyap, Senior Director of Governance, Risk and Compliance at Vanta, frames the issue this way: “The governance challenge that concerns me most is this: if an AI agent is attesting your controls, what assurance do you have over the agent itself?” Read the article on TechRadar.
Who should review the agent?
The deploying organization should assign a person or body with enough independence, authority, and access to assess the agent. The reviewer might be an internal expert who was not involved in front-line development, or an external assessor. What matters is that the reviewer can challenge the agent’s claims and the interests or assumptions of the team operating it.

NIST’s voluntary AI Risk Management Framework (AI RMF 1.0, 2023) says independent review can improve test effectiveness and help mitigate internal bias and conflicts of interest. Its Measure function allows internal experts who are not front-line developers and/or independent assessors to participate in regular assessments. NIST does not designate one universal agent attester. See NIST’s AI RMF Measure and Manage guidance.
What do the standards actually establish?
| Framework or standard | What it covers | What it does not establish |
|---|---|---|
| NIST AI RMF 1.0 (2023) | Voluntary guidance for assessment, documentation, deployment-relevant evaluation, production monitoring, and continued risk measurement. | A universal certification scheme or designated authority for individual AI agents. |
| ISO/IEC 42001:2023 | An organization-wide AI management-system approach to AI-related risks and opportunities. | Proof that every AI application or agent in a certified organization behaves correctly. |
| ISO/IEC 42006:2025 | Requirements for bodies that audit and certify AI management systems against ISO/IEC 42001, including bodies involved in assessing those certifiers. | Independent verification of every action taken by an individual agent. |
| NIST AI Agent Standards Initiative and NCCoE concept paper | Work on voluntary guidance, interoperable standards and protocols, agent identity and authentication, security evaluation, and applying identity and authorization standards to agents. | A completed, universal agent-certification system. |
| IEEE P1968 | A recommended-practice project for governance of autonomous AI-agent systems, including auditable and explainable decisions, independent defense-in-depth safety controls, and resilience when systems degrade or fail. | A universal certification or a prescription of specific technologies, vendors, models, or legal interpretations. |
ISO/IEC 42001 concerns the organization’s management system, not a detailed examination of every application. ISO/IEC 42006 concerns the bodies auditing and certifying that system. A 42001 certificate therefore should not be presented as evidence that a particular agent is safe or correct. ISO/IEC 42001:2023 and ISO/IEC 42006:2025 describe those respective scopes.

NIST describes its agent work as an initiative and research activity, while the NCCoE identity and authorization paper is a concept paper. IEEE P1968 is likewise a project and recommended-practice track, not a finished universal assurance regime. NIST’s AI Agent Standards Initiative, its NCCoE concept paper, and IEEE P1968 provide current context for this evolving work.
What should a buyer or risk owner ask?
Who controls the assessor?
Identify who reviews the agent, how that person or body is independent from development and operation, what access they have, and whether they have disclosed conflicts. A reviewer who cannot inspect relevant evidence or call for remediation cannot provide meaningful assurance.
Rank #3
Can the evidence be checked outside the agent’s own account?
Ask for traceable records of the agent’s identity, permissions, data and tools accessed, governing policy, decisions and actions, human approvals, exceptions, and changes. Evidence should be challengeable and drawn from relevant systems where possible, rather than resting only on the agent’s narrative or a collection of screenshots.
What did the evaluation test?
Request the test methods, tools, criteria, limitations, and results. Check whether evaluation conditions resemble the intended deployment and whether the testing covers risks relevant to the use case, such as security, reliability, and privacy. A pre-deployment check alone cannot establish continuing performance.

Which actions require human approval?
Set the agent’s data and tool access before launch, using the least privilege practical for its task. Decide which high-impact actions—such as changing access, deleting data, or moving money—require human approval. Establish how people can stop or roll back an action.
What triggers monitoring and reassessment?
Define how the organization will detect control drift and reassess when the model, tools, permissions, connected services, policies, or operating context changes. Choose runtime safeguards appropriate to the risk, which may include time-limited access, segmentation, circuit breakers, and containment.
These questions are a practical way to apply the governance recommendations and NIST guidance; they are not a formal checklist published by either source. NIST calls for regular assessment, documentation of test sets and tools, evaluation in conditions similar to deployment, production monitoring, and continued tracking of existing and emerging risks.

An internal independent review, an ISO/IEC 42001 certification, and an agent-focused technical evaluation answer different questions. Compare them on scope, independence and conflicts, access to evidence and reproducibility, test coverage and deployment relevance, frequency and change triggers, and authority to require remediation or stop operation. The cited materials do not define a common scoring scheme across these options.
