Why “Presumption of Conformity” Under the EU AI Act Changes the Compliance Game-But Can’t Be Your Shortcut (Yet)
AI compliance is no longer a technical box for specialists-it is now a test of executive responsibility and a reputation catalyst for your entire organisation. On paper, “presumption of conformity” looks like a silver bullet: achieve it, and suddenly the enforcement burden shifts-the regulator must prove you’ve breached the rules rather than you having to demonstrate your innocence up front. That’s a comforting prospect for any board or CISO facing the next wave of audits and market scrutiny. But the reality-especially in mid‑2024-is both sharper and less forgiving.
If you’re betting your next tender or regulator meeting on presumption alone, you’re already playing catch-up.
Many compliance teams are doubling down on ISO/IEC 42001 and similar frameworks, expecting instant regulatory protection for their AI systems. The logic is seductive, yet incomplete. The precise legal shield only lifts when your controls conform to a “harmonised standard”-one that has survived the EU’s legislative grind and been published in the Official Journal of the European Union (OJEU). Right now, for AI, that gold standard does not exist.
This catch turns the “presumption” dream on its head. What looks like a finish line is really just a checkpoint-one your competitors are also racing toward, but that shifts forward every time lawmakers, standard bodies, or courts revisit the fine print. If your organisation’s compliance storey relies on a future “get out of gaol free” card, both your executive credibility and procurement options take a hit-sometimes where it’s most visible.
The Boardroom Stakes: Perceived Safety Nets and Market Realities
For a compliance officer, “presumption” should read as risk transfer, not risk removal. Investors, customers, and partners are watching which organisations embed readiness, not just certificates, into ongoing practice. The difference between hard evidence and hope is now the line between reputational gain and operational vulnerability.
Book a demoAre All “AI Standards” Created Equal? Why Only OJEU-Listed Harmonised Standards Deliver Presumption
It’s tempting to treat any industry standard as a compliance passport. That’s never been true in European law, and under the AI Act, the gap is even starker. ISO/IEC 42001 and similar schemes demonstrate that your team values governance, but alone they won’t change the outcome if the regulator comes knocking. The only “presumption-of-conformity” that matters emerges from harmonised standards published explicitly in the OJEU.
Even after the toughest audit, an ISO/IEC 42001 badge without OJEU listing is a credibility lift, not a legal shield.
Here’s what that means in real-world terms:
- ISO/IEC 42001 is globally respected, and adopting it builds operational maturity.:
- But only harmonised standards-those shaped by EU-recognised bodies and released into the OJEU-bestow actual presumption.:
- Certification to sector, national, or even international frameworks remains valuable, but legally secondary.:
The Harmonisation Playbook: Lengthy, Exacting, and Relentless
- The European Commission issues a Standardisation Request (SReq) to CEN/CENELEC.
- These bodies start with existing ISO standards, revise them for EU priorities, and submit draughts for public and regulatory comment.
- The final step? Formal adoption in the OJEU after full scrutiny-a process running months or even years behind technology cycles.
Procurement teams and regulators now routinely ask: is this certificate listed in the OJEU? Unless the answer is yes, your controls need to be documented and justified, line by line, under the AI Act. Shortcut thinking leads nowhere.

Is ISO/IEC 42001 Harmonised for the AI Act? The Legal Reality Behind the Certificates
ISO/IEC 42001, released in late 2023, has quickly become the global reference for AI risk management. Within the community, holding 42001 connotes strength-your controls are tested, your governance is visible, your team has done the work. But ISO/IEC 42001, as of mid-2024, remains outside the harmonised circle for the EU AI Act.
A certificate is not a shield-unless OJEU says so.
For an executive, the implications are brutal in their clarity:
- Certificates are not enough.: Each control must precisely map to an AI Act provision in your technical file-no short-cuts, no broad statements, no one-size-fits-all assurances.
- Regulators expect proof, not promises.: If challenged before harmonisation, your team will need clause-by-clause evidence.
- Harmonisation is a moving target.: When ISO/IEC 42001 is (eventually) harmonised, the legal shield will appear-but until then, only evidence counts.
A compliance posture that treats standards as “set and forget” falls short by design. The best teams use ISO/IEC 42001 as a living foundation, getting ready to pivot the moment the OJEU listing lands.
When Will Harmonised AI Standards Actually Arrive in the OJEU?
Many mature organisations are tracking the regulatory pipeline for harmonised AI standards as if watching a release clock. Industry chatter pegs April 2025 as the earliest plausible OJEU entry for CEN/CENELEC-adapted versions of ISO/IEC 42001. Yet the full adoption-and operational impact-lags behind publication.
As of August 2025, no harmonised AI standards are OJEU-listed. Timeline delays are industry-wide, not just technical.
What this means for your compliance readiness:
- No protection today: -AI Act enforcement begins before any gold-standard is available.
- Smoother transitions tomorrow: -the earlier your records, processes, and evidence align with provisional draughts, the less scramble and risk with each regulatory update.
- Procurement friction grows: -buyers and partners increasingly seek OJEU citations, testing whether claims of “confidence” rest on technical merit, not badges.
Smart teams interpret the delay as licence to harden their documentation and monitoring-jumping the curve when standards finally land instead of watching rivals snap up contracts and regulatory goodwill.

How Can You Prove AI Act Compliance Before Harmonised Standards Enter Force?
AI Act enforcement doesn’t pause for harmonisation. Right now, organisations have two choices in the eyes of regulators:
1. Use OJEU-Harmonised Standards (when-and if-they arrive)
- Documents and controls mapped directly to a harmonised OJEU standard will, when available, transfer the burden to authorities for most liability questions.
- Until then, no shortcut exists.
2. Build Clause-by-Clause, Living Technical Files (the current reality)
- Every AI Act provision must be reflected in documents, process evidence, and operational controls-down to the letter.
- “Catch-all” certificates or generic statements cannot substitute for granular mapping.
- Regulators and partners may require independent verification or direct access to your technical file.
Living technical files and modular evidence beat panic audits every time.
Failure to map and evidence these details is the single largest source of compliance failure discovered by early AI Act readiness assessments. Savvy CISOs design living documentation-versioned, update-ready, and built to swap in harmonised references the day they arrive-embedding agility into compliance, not treating it as crisis response.
Are There Fast-Lanes or Carve-Outs? Who Gets Partial Presumption-And Where’s the Limit?
The only “express track” under the AI Act applies to narrow, high-risk AI applications-mostly those whose training data or cybersecurity controls fit existing schemes already harmonised under other EU legislation, like the Cybersecurity Act.
Presumption in one control domain never covers the entire AI Act.
What does this look like in practice?
- Restricted presumption: -if your AI system’s cybersecurity is certified under an OJEU-listed scheme, only those controls gain presumption (not others, such as transparency, oversight, data governance).
- Partial compliance: -systems meeting strict training data standards in Article 10(4) get limited presumption-but must still map every other requirement.
- No magic certificate: -there’s no path to full legal safety without full-system evidence and readiness.
Attempting to stretch a carve-out into broad immunity just flags your programme for deeper scrutiny. In the search for shortcuts, organisations risk being left behind when boards and buyers demand credible, system-wide compliance.

How High-Performance Teams Engineer Harmonisation Readiness-Now
Top-performing compliance teams don’t just wait-they engineer for flexibility and audit-readiness even as the landscape shifts. This is less about buying shelfware, more about continuously tuning your organisation’s documentation, oversight, and technical files to anticipate harmonised standards.
Hallmarks of This Approach
- Continuous gap analysis: -compare your controls to both current law and projected harmonised text; update your gap analysis dynamically and log version history.
- Agile technical documentation: -configure your records so new references, standards, or OJEU entries can drop in overnight. Use modular, role-based structures-ISMS.online supports this out of the box.
- Regulatory intelligence: -assign a stakeholder to monitor all CEN/CENELEC, OJEU, and EU Commission releases; publish alerts internally so your pivot time is measured in hours, not months.
- Proof before presumption: -always evidence operational maturity: show why your controls work, not just where they live on a policy sheet.
Teams with living, updatable technical files become partners of first choice for buyers, not last-minute gap fillers.
The payoff is sharply practical: competitive wins, safer audits, and board-level confidence that compliance is against a real risk-never a paper chase.
Delay Is No Longer a Neutral Move-It’s a Strategic Risk for the Board
Compliance hesitation used to mean little more than paperwork delays. Today, waiting is a reputational gamble boards-and C-suites-cannot afford:
- Buyers demand harmonised evidence now: -especially in regulated sectors, public service, and finance. “ISO” and “good practice” are not enough when contracts specify OJEU cross-references.
- Retroactive compliance is always more painful: -deferrals only grow the cost, complexity, and potential for nasty surprises later.
- ISMS.online lets you leap the queue: -with living clause-by-clause mapping, forward-linking to future harmonised standards, and real-time OJEU tracking, your compliance asset is as current as tomorrow’s legal updates.
Delaying live compliance is now a financial and reputational liability-and a gift to your competitors.
Boards who act early send a signal of resilience to markets and partners, closing the door to expensive and disruptive catch-up.

Frequently Asked Questions
Who actually grants presumption of conformity for the EU AI Act-and how does this tilt the compliance burden?
Presumption of conformity is only triggered when your AI system aligns with a harmonised standard published in the Official Journal of the European Union (OJEU). That’s not folklore-it’s a legal shield granted by EU regulators, but only after CEN, CENELEC, or ETSI convert a technical standard into an EU-tailored “EN” and the Commission lists it. Until then, every system, regardless of how polished or how ISO-certified, is a target for clause-by-clause scrutiny. For compliance teams and CEOs, that means the real reward isn’t a trophy on the wall-it’s the regulator now having to prove a gap instead of you defending every line.
OJEU citation flips the compliance game: now you’re presumed secure, until proven not.
This perspective isn’t theoretical. In current practice, compliance means endless artefact collection, granular mapping, and audit-ready files that withstand cross-examination. Harmonised standards, once real, collapse this friction. Auditors pivot from interrogators to verifiers, procurement cycles shrink, and your legal exposure drops. But here’s the catch: to date, no harmonised AI Act standard exists. Every assurance, claim, or audit still rides on direct evidence-not declarations or certificates.
What organisations must heed this regime?
Any business that develops, deploys, or purchases AI for the EU market is in the scope. The implication for global entities is simple: don’t expect relief from OJEU harmonisation until the ink is dry. Run every internal mapping as though every regulator intends to challenge it-because, right now, they do. Early adopters are wiring platforms like ISMS.online into their workflows to preempt the switch, so when a standard finally arrives, their compliance flips instantly from effort to default.
How do harmonised standards distinguish themselves from ISO/IEC 42001 and industry frameworks?
Only harmonised standards give you the legal shortcut-a presumption of conformity hardwired into the EU Act. Their creation is a tightly governed affair: CEN, CENELEC, or ETSI work under formal Commission mandate, and OJEU listing is essential. ISO/IEC 42001, though widely respected, lacks this legal muscle-unless the EU specifically adopts it, it’s just a signal of discipline, not a shield.
You’ll see procurement officers, due diligence teams, and auditors all converge on this question: “Is it in the OJEU?” If not, every control, every safeguard, and every certification will still be independently examined. Buyers may applaud ISO/IEC 42001 for structure and management rigour, but won’t accept it as a pass for legal compliance.
When do frameworks like ISO/IEC 42001 function as a practical asset-and when do they fail?
- Governance enhancer: ISO/IEC 42001 sets a credible foundation for risk management, structure, and proactive governance. It proves cultural buy-in at board level.
- No legal presumption: Without OJEU citation, even a full badge won’t shift the EU’s expectation for evidence. You’ll still need a living technical file, mapping every obligation to operational proof.
Table: Harmonised Standard vs. ISO/IEC 42001 snapshot
| Attribute | Harmonised Standard (OJEU) | ISO/IEC 42001 (Global Voluntary) |
|---|---|---|
| Grants legal presumption? | Yes | No |
| Mandatory for EU procurement? | Yes | No; may help, never sufficient |
| Adaptation model | EU commission mandated | International consensus |
When will ISO/IEC 42001 deliver legal presumption-and what are the real-world hurdles?
Legal presumption from ISO/IEC 42001 only arises once CEN and CENELEC, at the EU’s request, adapt the standard-typically adding a Z Annex for EU-specific legal and sector needs. Only when this EU-flavoured version is officially listed in the OJEU does presumption apply. Until then, ISO/IEC 42001 delivers structure, not immunity.
CEN and CENELEC’s adaptation process is underway, with the earliest possible OJEU publication expected for spring or summer 2025. Even at that point, contracts, procurement templates, and audit checklists will lag before catching up. Teams betting on a snap transition should plan for a phased journey-expect internal and external systems to run mixed models for months.
ISO/IEC 42001 earns its teeth only after the OJEU lists it. Monitor daily, but don’t postpone actionable mapping for a golden shortcut.
Harmonisation process: how the clock ticks
| Step | Expected Timing |
|---|---|
| EC tasks standards bodies | Done (2024) |
| Drafting + EU Z Annex adaptation | 2024–2025 |
| OJEU citation/publication | From April 2025 onwards |
| Real procurement impact | Summer 2025 and later |
What does AI Act compliance look like before OJEU standards are published?
Compliance before OJEU publication means “old school” rigour. You’ll need to show, for each AI Act clause, exactly what control, document, process, or audit record answers the demand-no matter how many certifications you display. Living, mapped technical files-not static PDFs-are the tool of choice. Every change management update, risk assessment, or evidence log must be instantly traceable.
ISMS.online gives organisations a clause-level advantage: as soon as the OJEU standard appears, their technical files can pivot reference sets overnight, keeping external audits at arm’s length and satisfying procurement.
How do you present defensible proof when there’s no harmonised standard fallback?
Show auditors granular links from every requirement to operational, living evidence-versioned documentation, risk logs, and named responsible roles. Static certificates or badges, no matter how gleaming, won’t close the loop. The teams winning contracts and trust are the ones who run modular, auto-updating mapping, not spreadsheet relics.
Are there any narrow exceptions-partial or domain-specific legal presumptions-available now?
Partial presumptions operate in a handful of technical corners: some OJEU-listed certifications in cybersecurity (ENISA or NIS2-aligned schemes), or narrowly scoped Article 10(4) training data documentation. These carve-outs provide legal comfort only for the covered domain-the rest of your AI system remains under full clause scrutiny, even if “compliance” is claimed on marketing slides.
Any organisation promoting “full AI Act compliance” by virtue of a single, non-OJEU badge exposes itself to regulatory questioning and procurement slowdowns. No single product, certificate, or toolkit currently grants total safe harbour.
| Domain | Presumption Now? | Cover Scope |
|---|---|---|
| Cybersecurity (OJEU cert) | Yes-domain-specific only | Security provisions only |
| Art 10(4) training data | Yes-limited documentation | Document flow only |
| Other AI controls | No | Clause-by-clause evidence |
What proactive actions give compliance leaders an edge-before the OJEU benchmark is live?
The operations blazing a trail now treat clause-mapping and evidence as first-class projects, not grudging chores. The practicalities:
- Map every AI Act requirement to an active, operational artefact-don’t leave gaps.
- Replace brittle checklists with live, modular technical files that update as soon as the OJEU standard is cited.
- Build a rapid-response layer: assign a compliance lead to monitor CEN/CENELEC and OJEU feeds, integrating new legal requirements at the drop of a hat.
- Educate executives and procurement teams: certifications and frameworks build trust, but only robust evidence mapping satisfies audits and wins contracts.
The top performers make evidence living-versioned, automated, and ready to swap compliance DNA as soon as the OJEU flips the switch.
Industry pacesetters are embedding platforms like ISMS.online that automate clause mapping, real-time OJEU and regulatory update tracking, and technical file generation purpose-built for the modern AI Act audit. The dividend: faster contract wins, bulletproof audits, and a reputation for being prepared before the crowd even knows the rules have changed.
Turning compliance into a living process now isn’t just about risk-it’s about seizing the lead position. Replace apathy with operational readiness and your organisation becomes the contract magnet. Let competitors cling to old checklists. Your roadmap is built for the regulator’s playbook-and ISMS.online locks that advantage before harmonised standards even hit the market.
