AI governance, certified.

ISO/IEC 42001 is what enterprise buyers now point to when they ask “do you govern AI?” It is the world’s first certifiable AI Management System (AIMS): ten clauses and thirty-eight Annex A controls an accredited Certification Body audits and registers on the IAF database. For companies shipping AI, it turns an open-ended governance question into a single, verifiable answer.

Our stance: certify it, don’t decorate it. 42001 only earns its keep if you operate the AIMS; otherwise it is a wallpaper credential.

§ 0 · Why it matters

Why organizations pursue ISO 42001.

  • The AI-governance question. Enterprise buyers increasingly ask how vendors govern AI before approving them. 42001 is the answer procurement recognizes.
  • EU AI Act alignment. The AIMS maps closely to the Act’s risk-management, data-governance, and documentation duties: useful evidence as enforcement ramps.
  • Board & investor assurance. A certified management system gives directors and investors a defensible answer on how AI is overseen.
  • Independent, registered proof. A CB-issued certificate resolves on the IAF database: third-party verification, not a self-claim.
  • A first-mover trust signal. As the first certifiable AI standard, 42001 still differentiates: a credible governance signal ahead of the market.
Context

A 42001 certificate does not certify that any model is safe, unbiased, or correct. It demonstrates that you have a management system capable of governing AI risk across the lifecycle. For most organizations, that distinction is exactly what buyers and regulators are asking them to prove.

The governance engine

One management system.
Every AI risk it governs.

  • AI Risk Management
  • Impact Assessment
  • Data Governance
  • System Lifecycle
  • Human Oversight
  • Transparency
  • Evidence & Logging
  • Audit & Improvement

ISO 42001 exists because buyers and regulators need confidence that AI risk, impact assessment, data governance, and the model lifecycle operate as one accountable system.

AI accountability, engineered.
A Nexurion AI governance working session: senior practitioners around a boardroom table with the AI Governance Framework on screen — ISO/IEC 42001, NIST AI RMF, EU AI Act, OWASP LLM Top 10, MITRE ATLAS, and AIUC-1 — reconciled into one program.
§ I · The standard

What ISO 42001 actually is, in plain English.

The one-line version

An accredited certificate that you operate a working AI Management System — it certifies the system, not any single model. Excellent evidence of governance maturity; not proof a model is safe.

CB-certifiedaccredited body Public certificateresolves on IAF 10 HLS clausesthe management system 38 Annex A controls9 objectives 3-yr cycleannual surveillance
The standard, in full

ISO/IEC 42001:2023 is the first internationally-recognized management system standard for artificial intelligence, published on 18 December 2023 by ISO/IEC Joint Technical Committee 1, Subcommittee 42. It is structured like ISO 27001:2022: ten High-Level Structure clauses describing the management system, a normative Annex A of 38 controls under 9 objectives, and informative annexes (B implementation guidance, C risk sources, D sectoral use). If you have ever stood up an ISMS, the architecture is familiar within ten minutes.

The unit of certification is the AIMS: not a model, not a product. You define a scope, demonstrate that the AIMS addresses the Annex A controls you declare applicable in your Statement of Applicability, then operate it long enough for an accredited Certification Body to sample evidence at a Stage 2 audit. The certificate is issued by the CB, not ISO; the CB is accredited by an IAF MLA signatory (ANAB, UKAS, DAkkS, JAS-ANZ) and the certificate number resolves on IAF CertSearch.

What it is not: a product certification. 42001 does not certify that a model is safe, unbiased, or correct. It certifies you have a management system capable of governing AI risk across the lifecycle: excellent evidence of governance maturity, and almost none of system-level conformance. Use it for what it is.

The path to certified

AI governance, answered.

AI risk question
Governance review
AIMS evidence
Procurement
Contract

A qualified prospect wants to buy. Then their risk team asks how you govern AI.

You point to your 42001 certificate. The governance review opens instead of stalling.

They sample your AIMS evidence: impact assessments, lifecycle records, logs. It is already there.

Procurement has independent, registered assurance to proceed. No questionnaire marathon.

The deal advances. Answered.

All cleared. A live 42001 certificate compresses the AI-governance review from weeks to a link.

§ I.5 · Why us

A boutique firm, not a compliance factory.

The compliance factory
  • Canned SOW, identical for every client
  • Junior associate does the work, partner sells it
  • Scope padded with line items you don't need
  • "You don't qualify" if you don't fit the template
  • Surprise change-orders mid-engagement
Nexurion
  • SOW built around your business, not a template
  • Senior practitioner from day one: no junior hand-off
  • We cut unnecessary cost: you pay for what moves the audit
  • We edit SOW language together until both sides agree
  • Fixed fee, written: no surprise change-orders
How we scope

We never say "you don't qualify."

Our approach

If a framework isn't right for you yet, we'll tell you: and tell you what is. When it is right, we sit down and shape the statement of work to your reality: your stack, your team, your timeline, your budget. The deliverable bends to your business. You do not bend to a canned deliverable.

§ II · Scope decoder

Does this apply to you?

A quick filter we run on every intake call. The more of these that point to “yes,” the more likely ISO 42001 belongs on your roadmap inside twelve months.

Interactive · 3 questions

ISO 42001 fit check

1. Do you develop, deploy, or distribute AI systems used in commerce?
2. Has any enterprise buyer asked about AI governance in the last 6 months?
3. Do you place AI systems on the EU market or serve EU users?
Answer above: we’ll tell you whether ISO 42001 is the right next step.
Stage 1 · AIMS designed

AIMS designed.
Not yet operating.

Evidence begins
accumulating.

Internal audit confirms it works.

Certified.
Surveillance begins.

Stage 1 reviews the AIMS on paper: scope, AI policy, Statement of Applicability, and the Clause 6 risk and impact assessments. It proves the system is designed — not that it runs.

The AIMS goes live. Controls must now operate: impact assessments, lifecycle records, and event logs are captured continuously — not assembled before the audit.

Internal audit and management review test effectiveness across the period. Nonconformities are raised and closed — the loop is turning before the CB arrives.

Stage 2 passes. The CB issues a certificate that resolves on the IAF database, then returns for annual surveillance across the three-year cycle.

Assurance level
Buyers and regulators want the certificate. Not a design on paper.
STAGE 1 ISO 42001 AIMS · Certification Cycle Start 3 mo 6 mo 9 mo 12 mo + AIMS OPERATING EFFECTIVENESS Accredited certification · ISO/IEC 42001:2023 · 10 clauses · 38 Annex A controls
§ V · The clock

A first-time AIMS, realistically: 9 to 15 months.

From kickoff to a certificate that resolves on the IAF database. The chokepoint is rarely the audit; it is standing the AIMS up and operating it long enough to show evidence of effectiveness.

Mo 0 – 1
Gap & scope
Define the AIMS scope and AI-system inventory. Gap analysis against the 10 clauses and 38 Annex A controls. Output: a gap report and a scoped build plan. Hold ISO 27001 already? Much of Clauses 4–10 is reused.
Mo 1 – 4
Build the AIMS
AI policy, roles, the Clause 6 risk and AI system impact assessments (per ISO 42005), Statement of Applicability, and the lifecycle and data-governance controls. Documented information instrumented from day one.
Mo 4 – 8
Operate & evidence
The AIMS runs. Impact assessments, lifecycle records, and event logs accumulate. The internal-audit program executes; management review convenes at least quarterly.
Mo 7 – 9
Stage 1 audit
The CB reviews the AIMS design and documentation, confirms readiness for Stage 2, and flags gaps to close. A documentation-led review, not a deep evidence test.
Mo 9 – 15
Stage 2 + certificate
The CB samples evidence of effectiveness, raises any nonconformities, and on closure issues the certificate. Surveillance is scheduled; the three-year cycle begins.
Why teams hire Nexurion
§ VI · How Nexurion runs it

Built on your 27001 fabric. Senior partner from day one.

Partner-led from kickoff through Stage 2. Built on top of your existing management-system fabric. Audit-room delivered before the CB arrives.

Methodology detail

Most consultants hand you a policy template pack and a portal, then stop calling. We don’t. Every Nexurion 42001 engagement is led by a senior practitioner: the person on the engagement letter is the one reading your impact assessments, sitting in your management reviews, and on the call when the CB samples evidence. Read our methodology.

If you already operate an ISO 27001 ISMS, we build the AIMS on top of it: shared Clauses 4–10, one internal-audit program, one management review. We instrument the Clause 6 assessments and Annex A evidence from day one and hand the CB a read-only audit-room with every artifact pre-mapped to the clause or control it satisfies. More on our evidence model »

The goal is not only a certificate. It is an AIMS that is sustainable: cheaper and lower-effort to operate in year two than in year one, and durable across surveillance audits as your AI footprint grows. See engagement outcomes.

01
Senior practitioner from day one
The name on the engagement letter is the person reading your impact assessments. No junior hand-off.
02
Built on your 27001 fabric
Hold ISO 27001? We reuse Clauses 4–10 and the evidence library. No parallel management system.
03
Audit-ready evidence
A read-only audit-room, every artifact pre-mapped to the clause or Annex A control it satisfies.
04
Independent of the CB
We don’t issue the certificate, so our readiness carries no conflict. By design.
Engagement structure

Independent of the certification body: by design.

We are not a Certification Body and we do not issue 42001 certificates. That independence matters: a readiness partner whose firm also certifies has a conflict no engagement letter can paper over. We work alongside the IAF-accredited CB of your choice, or introduce you to bodies whose AI competence we’ve verified. Certification bodies »

What a senior partner prevents
§ VII · Where engagements stall

Six places a 42001 goes sideways.

After standing these up, the failure modes are consistent. Almost none are technical: they are about planning, scope, and ownership.

01 / Wallpaper cert

Certify it, don’t decorate it.

Why it happens
Teams chase the certificate without operating the AIMS. The CB samples evidence of effectiveness: a system that lives only on paper fails Stage 2, or earns a finding-laden certificate no buyer respects. Operate it, then certify it.
02 / Weak Clause 6

Annex A first, planning never.

Why it happens
Clients want to jump straight to controls. Without a real AI risk assessment and impact assessment, every Annex A control is decorative and the Statement of Applicability can’t be justified. Clause 6 comes first.
03 / Scope sprawl

Certify every AI system at once.

Why it happens
A 42001 scope is bounded. Covering every model, team, and entity in version one multiplies evidence and stalls the build. Start with the systems buyers and regulators actually ask about, then extend at surveillance.
04 / Shadow AI

Models nobody owns.

Why it happens
A team wired an LLM API into production with no impact assessment, no logging, no owner. Annex A.6 (lifecycle) and A.10 (third-party) will find it. Inventory before kickoff; govern or retire each system.
05 / 27001 in disguise

“Same ISMS, new logo.

Why it happens
42001 reuses the High-Level Structure, but the AI-specific work: impact assessment, lifecycle controls, data governance, transparency, is real and new. Copying an ISMS without it produces a thin AIMS that a competent CB will see through.
06 / CB mismatch

A body that doesn’t understand AI.

Why it happens
Not every Certification Body fields competent AI auditors yet. A certificate from a body that can’t probe your model lifecycle is worth less to a sophisticated buyer. Pick an IAF-accredited CB with verified AI competence: we’ll introduce you, no kickback.
§ VIII · Certification bodies

Certification bodies we’ve walked clean engagements with.

CB-neutralreferrals on fit, not fees
No referral feeswe accept none
AI-competentauditors who know model lifecycles
Bring your ownoften the same body as your 27001
How we work with certification bodies

We are CB-neutral by policy and refer on fit, AI competence, and IAF accreditation: never on referral fees (we accept none). After multiple engagements you learn which bodies field auditors who actually understand model lifecycles, and which treat 42001 as ISO 27001 with a new cover. We’ll introduce you to bodies whose AI competence and accreditation we’ve verified. Buyers and regulators check the accreditation behind the certificate: we make sure it holds up.

If you already hold a CB relationship from your ISO 27001 certificate, we’ll sit with their lead auditor and align scope, evidence format, and Stage 1 / Stage 2 cadence: often the same body can certify both. We’ve never had to disengage from a body mid-audit.

§ IX · Cross-mapping

ISO 42001 against the rest of the AI stack.

42001 is rarely the only AI framework your buyers and regulators name. The good news: most of the work overlaps. The bad news: the gaps are not where you think.

The stack

ISO 42001 against the rest of the AI stack.

ISO 42001 the AIMS NIST AI RMF ~70% overlap EU AI Act ~60% overlap ISO 27001 ~55% overlap ISO 23894 ~50% overlap OWASP LLM ~35% overlap SOC 2 ~25% overlap
Line weight indicates approximate overlap with ISO 42001. Higher overlap means more of the AIMS work carries directly into that framework. Detailed crosswalk below.

§ III · The management system

The ten clauses & Annex A controls.

42001 is built on the ISO High-Level Structure. Clauses 4–10 are the management system an auditor tests; Annex A is the AI-specific control set you justify in your Statement of Applicability. Every Annex A control defaults to applicable: you justify exclusions, not inclusions.

ClauseTitleWhat an auditor expects
4Context of the organizationInternal/external issues, interested parties, AIMS scope statement, inventory of AI systems with role (developer/deployer) and lifecycle stage.
5LeadershipAI policy signed by top management, assigned AIMS roles, evidence of leadership engagement: minutes, objectives, resourcing.
6PlanningThe hardest clause. AI risk assessment, AI system impact assessment (per ISO 42005), Statement of Applicability for the 38 controls, measurable AI objectives.
7SupportResources, AI competence (training records), awareness, internal/external communication, documented information.
8OperationOperational planning, AI risk treatment in practice, impact assessments, change control over models & data.
9Performance evaluationMonitoring & measurement, internal audit program, management review: quarterly minimum.
10ImprovementNonconformity & corrective action, continual improvement: a track record of NCs closed.

Annex A defines 38 controls across 9 objectives. Click each objective for the controls a CB will sample.

Annex A.4Resources for AI systems

A documented inventory of the resources the AIMS needs, and an explicit assessment of resources required across the lifecycle. Most clients confuse this with capacity planning: it is accountability.

A.4.2
Resource documentation
A maintained catalog of compute, data, tooling, and human resources allocated to in-scope AI systems.
A.4.3
Tooling resources
Identification and management of tools across the lifecycle: training, eval, deployment, monitoring.
A.4.4
System & computing resources
Documented compute / hardware allocation per system, with an audit trail of changes.
A.4.5
Data resources
Inventory of training, validation, and test datasets: provenance, licensing, intended use.
A.4.6
Human resources
Roles, competencies, and oversight responsibilities mapped to each AI system.

Annex A.5AI system impact assessment

The most-cited objective in EU AI Act conversations. A.5 demands a process for assessing impacts on individuals, groups, and society, with companion standard ISO 42005 giving the methodology. CBs sample these heavily.

A.5.2
Impact assessment process
A documented procedure invoked at design and at material change: not a one-time check.
A.5.3
Documentation of impact
Per-system impact records: stakeholders, harms, severity, mitigations.
A.5.4
Impact on individuals
Specific consideration of impacts on natural persons: bias, fairness, autonomy.
A.5.5
Impact on groups & society
Group-level impacts: protected classes, communities, societal and environmental effects.

Annex A.6AI system lifecycle: the heart of the standard

Ten controls covering objectives, design & development, verification & validation, deployment, operation & monitoring, technical documentation, and event logging. Mature MLOps already does ~70% of this; the gap is documentation.

A.6.1.2
Objectives for responsible AI
Documented goals for fairness, robustness, transparency: tied to the AI policy.
A.6.1.3
Responsible design & development
Design reviews, ethical considerations, threat modeling for AI-specific harms.
A.6.2.2
Requirements & specs
Functional, performance, fairness, robustness, explainability requirements per system.
A.6.2.3
Documentation of design
Model cards, datasheets, design decisions, hyperparameter logs.
A.6.2.4
Verification & validation
Eval datasets, performance criteria, bias testing, adversarial testing.
A.6.2.6
Deployment
Release criteria, approvals, rollback plans, staged rollout.
A.6.2.7
Operation & monitoring
Drift, performance, and incident monitoring in production against defined thresholds.
A.6.2.8
Event logging
Records of system events sufficient for audit and incident reconstruction.

Annex A.7Data for AI systems

Six controls on the data that feeds models: provenance, quality, and preparation, plus the governance an auditor expects before trusting any output.

A.7.2
Data for development
Defined requirements for the data used to develop and operate each AI system.
A.7.3
Acquisition
Sourcing, licensing, and lawful-basis records for acquired datasets.
A.7.4
Quality
Data-quality criteria: accuracy, completeness, representativeness, bias checks.
A.7.5
Provenance
Lineage records: where data came from and how it was transformed.
A.7.6
Preparation
Documented preparation, labeling, and feature-engineering steps.

Annex A.8–A.10Information, use & third parties

The outward-facing controls: what you tell users and interested parties, how the system is responsibly used, and how you govern the third-party AI you build on.

A.8.2
System documentation
Information for users: capabilities, limitations, intended use, human-oversight guidance.
A.8.3
External reporting
Channels for affected parties to raise concerns and receive responses.
A.9.2
Responsible use
Defined intended use and processes to prevent foreseeable misuse.
A.9.3
Objectives for use
Use aligned to organizational AI objectives and policy.
A.10.2
Third-party & supplier
Due diligence and allocation of responsibilities for third-party AI, models, and APIs.
A.10.3
Customers & users
Responsibilities communicated to customers who deploy or build on your AI.
§ X · 2026 outlook

42001 in its second year.

42001 was published in December 2023, and adoption accelerated through 2025 as the EU AI Act timeline firmed up. Four things to watch in 2026:

  • EU AI Act harmonization. CEN-CENELEC is drafting harmonized European standards for the Act. 42001 is widely expected to inform them: a 42001 AIMS is strong positioning, not a substitute for conformity assessment.
  • CB accreditation maturing. More IAF-accredited bodies now offer 42001 and auditor AI competence is rising. The gap between a credible certificate and a rubber-stamp is narrowing: but still real.
  • ISO 42005 in force. The AI system impact-assessment standard gives Clause 6 and Annex A.5 a concrete methodology. CBs are sampling impact assessments more rigorously as a result.
  • Buyer demand. Enterprise and public-sector buyers increasingly name 42001 in AI-governance questionnaires. See our AI governance practice »

§ XI · Pairs with

42001 is rarely the only AI framework.

What we typically scope alongside it: in order of how often the question comes up.

§ XII · FAQ

Frequently asked.

Are we certified when the report is issued? +
No. SOC 2 is an attestation report, not a certification. It does not result in a certification certificate, and there is no public registry of SOC 2-compliant organizations. You hold a private CPA-issued report your buyers read under NDA. Marketing should say "we maintain a SOC 2 Type 2 report": not "we are SOC 2 certified."
How long does the first Type 2 take? +
Realistically, 8 – 14 months from kickoff. Readiness (4 – 16 weeks), audit period (3 – 12 months), fieldwork (6 – 10 weeks). Smaller, well-instrumented teams compress to ~7 months. See full timeline.
What does it cost? +
For a Type 2 first-time issuance: $30 – 90k for the auditor, $35 – 75k for readiness + ConMon (Nexurion fee depends on scope). Renewal years drop sharply. See pricing structure »
Should we run SOC 2 and ISO 27001 at the same time? +
Often, yes. ~85% control overlap means you do roughly 1.3x the work for two reports. We sequence them so the SOC 2 audit period runs while the ISO certification audit happens, and one evidence library serves both.
Can we self-attest? +
No: a SOC 2 must be issued by a licensed independent CPA firm under SSAE 18. Anything else is a self-assessment, which most buyers will reject.
Does our existing HITRUST or ISO 27001 cert satisfy a SOC 2 ask? +
Sometimes. Some buyers accept HITRUST CSF in lieu of SOC 2, particularly in healthcare. Most don’t. ISO 27001 is rarely accepted in lieu of SOC 2 in U.S. enterprise procurement, though it sometimes is in EU.
What’s the difference between SOC 1, SOC 2, and SOC 3? +
SOC 1 covers controls relevant to a customer’s financial reporting (think payroll providers, custodians). SOC 2 covers the Trust Services Criteria: security, etc. SOC 3 is a sanitized SOC 2 marketing document with no exceptions detail; auditors issue it alongside.
