1. Overview
What the EU AI Act Is
Regulation (EU) 2024/1689, commonly called the EU AI Act, is the world's first comprehensive horizontal regulation of artificial intelligence. It entered into force on 1 August 2024 with phased application: prohibited practices (Article 5) and AI literacy obligations (Article 4) from 2 February 2025; general-purpose AI model obligations (Chapter V) from 2 August 2025; the bulk of high-risk obligations (Article 6 / Annex III) from 2 August 2026; and high-risk systems embedded in regulated products (Annex I) from 2 August 2027. The full consolidated text is published in the Official Journal at eur-lex.europa.eu.
Who It Applies To
The Act applies extraterritorially. It binds providers placing AI systems on the EU market, deployers using AI systems in the EU, importers and distributors, and any provider or deployer outside the EU whose system outputs are used in the Union. This is broader than GDPR in scope of obligation, narrower in scope of subject matter.
Risk Tiers
- Prohibited AI practices (Article 5) — social scoring by public authorities, real-time remote biometric identification in public spaces (with narrow exceptions), exploitation of vulnerabilities, predictive policing based solely on profiling, untargeted facial-image scraping, emotion inference in workplaces and education.
- High-risk AI systems (Article 6, Annex III) — eight defined areas including biometric identification, critical infrastructure, education and vocational training, employment and worker management, access to essential services, law enforcement, migration and border control, administration of justice and democratic processes.
- Limited-risk AI systems — transparency obligations (Article 50): inform users when interacting with AI, label deepfakes, disclose synthetic content.
- Minimal-risk AI systems — no specific obligations beyond voluntary codes.
- General-purpose AI (GPAI) models (Chapter V) — separate regime; additional obligations for GPAI with systemic risk (Article 51 thresholds, currently 10^25 cumulative training FLOPs).
Outcome
For most high-risk providers, the Act requires a conformity assessment (Article 43), CE marking, registration in the EU database, and post-market monitoring (Article 72). For deployers, obligations include fundamental rights impact assessment (Article 27) for certain Annex III systems, human oversight, monitoring, and incident reporting.

2. Scope & Applicability
Material Scope
An "AI system" under Article 3(1) is a machine-based system designed to operate with varying levels of autonomy, that may exhibit adaptiveness, and that infers from inputs how to generate outputs (predictions, content, recommendations, decisions) that can influence physical or virtual environments. The European Commission published guidelines clarifying this definition in February 2025.
Annex III High-Risk Areas
- Biometric categorization, emotion recognition (outside the prohibited contexts), remote biometric identification
- Critical infrastructure (digital, road traffic, water, gas, heating, electricity)
- Education and vocational training (admission, evaluation, monitoring)
- Employment, workers management, access to self-employment (recruitment, performance, allocation of tasks, monitoring)
- Access to essential private and public services (credit scoring, public benefits, emergency services dispatch, insurance pricing for life and health)
- Law enforcement (within scope of Union competence)
- Migration, asylum, border control
- Administration of justice and democratic processes
Article 6(3) Derogation
A system that would otherwise fall in Annex III is not high-risk if it does not pose a significant risk of harm. The provider must document and justify this derogation. The European AI Office is expected to publish further guidance.
Provider vs Deployer
- Provider — develops or has developed an AI system and places it on the market or puts it into service under its own name. Heaviest obligation set.
- Deployer — uses an AI system under its authority, other than for personal non-professional activity. Obligations include human oversight, monitoring, fundamental rights impact assessment in defined cases, and incident reporting.
- Importer, Distributor, Product Manufacturer, Authorized Representative — each have defined accountability under Articles 22–27.
GPAI Models
Models trained on broad datasets capable of general tasks are GPAI. From 2 August 2025, providers face documentation, copyright, and transparency obligations. Models exceeding the Article 51 systemic-risk threshold (currently 10^25 cumulative training FLOPs) face additional model evaluation, adversarial testing, incident reporting, and cybersecurity obligations under Article 55. The EU AI Office co-developed a Code of Practice for GPAI, finalized in mid-2025.
3. Core Principles
The Act builds on seven principles drawn from the High-Level Expert Group's Ethics Guidelines: human agency and oversight; technical robustness and safety; privacy and data governance; transparency; diversity, non-discrimination and fairness; societal and environmental wellbeing; accountability. These principles map to the operational obligations in Title III for high-risk systems.
Key operational principles for high-risk providers:
- Risk management is an iterative, lifecycle process (Article 9)
- Data governance must address relevance, representativeness, errors, and bias (Article 10)
- Technical documentation must be maintained current (Article 11, Annex IV)
- Logging is built-in by design (Article 12)
- Transparency to deployers includes intended purpose, performance characteristics, and human oversight measures (Article 13)
- Human oversight is designed in (Article 14)
- Accuracy, robustness, and cybersecurity are validated and maintained (Article 15)
4. Control Breakdown
Article 9 — Risk Management System

Articles 16–21 — Provider Obligations
Quality management system, technical documentation maintenance, registration in the EU database (Article 49), conformity assessment, EU declaration of conformity (Article 47), CE marking (Article 48), authorized representative if not established in the EU.
Articles 26–27 — Deployer Obligations
Operate per instructions, assign competent human oversight, monitor operation, log retention, inform provider of incidents and risks, conduct a Fundamental Rights Impact Assessment (Article 27) for certain Annex III public services and credit scoring contexts.
Article 43 — Conformity Assessment
For most Annex III systems, internal control by the provider (Annex VI). For biometric identification systems and Annex I product-embedded systems, third-party assessment by a Notified Body. Output: EU declaration of conformity and CE marking.
Articles 72–73 — Post-Market Monitoring and Incident Reporting
Providers maintain a post-market monitoring plan, collect operational data, document corrective actions. Serious incidents (Article 3(49)) and widespread infringements must be reported to the market surveillance authority within defined timelines (immediately for fatal incidents; not later than 15 days otherwise; shorter for incidents linked to fundamental rights infringement under Article 73(3)).

6. Technical Implementation Guidance
Mapping to ISO 42001
The AI Management System defined in ISO/IEC 42001:2023 provides the governance backbone for AI Act compliance. Article 17 (quality management) maps to Clauses 5–10 of ISO 42001. Article 9 (risk management) maps to Clauses 6.1 and 8.2 of ISO 42001 plus the Annex A controls in A.5 (policies), A.6 (organization), and A.8 (AI lifecycle). The two are not interchangeable, but an ISO 42001-aligned program meets most of the documentation expectations of the AI Act. See our ISO 42001 service.
Privacy Overlap
AI systems processing personal data remain fully bound by GDPR. Article 10(5) of the AI Act permits processing of special-category data for bias correction under strict conditions. A DPIA under GDPR Article 35 should be performed where applicable and aligned with the FRIA where the deployer triggers Article 27. See our GDPR service and ISO 27701 service.
Data Governance
- Maintain dataset provenance, including supplier or scraping records
- Document annotation methodology and inter-annotator agreement metrics
- Run bias diagnostics across protected and intersectional categories
- Test on representative populations including edge cases relevant to the intended purpose
Adversarial Robustness
- Threat-model the inference pipeline: data poisoning, evasion attacks, model extraction, membership inference, prompt injection for generative models
- Apply input sanitization, output filtering, and rate limiting
- For GPAI with systemic risk, document red-team evaluations against the Code of Practice methodology
Human Oversight
- Implement override and stop functions
- Train operators in the system's limitations and confidence indicators
- Log oversight interventions for audit
Cybersecurity
- Integrate the AI system into the existing ISMS (ISO 27001 or SOC 2 controls)
- Threat-model model serving infrastructure and protect model weights and training data
- Continuous monitoring of inference for anomalous patterns
7. Policy & Procedure Requirements
- AI Policy (linking provider/deployer roles to governance)
- Risk Management Procedure (Article 9)
- Data Governance Standard (Article 10)
- Technical Documentation Standard (Annex IV)
- Logging and Monitoring Standard (Article 12)
- Instructions for Use Template (Article 13)
- Human Oversight Procedure (Article 14)
- Cybersecurity for AI Standard (Article 15)
- Post-Market Monitoring Plan (Article 72)
- Serious Incident Reporting Procedure (Article 73)
- AI Literacy Program (Article 4)
- Fundamental Rights Impact Assessment Template (Article 27)
- Quality Management System Procedure (Article 17)
For combined ISO 42001 + AI Act + ISO 27001 deployments, most documents serve all three. See our ISO 42001 service.
8. Audit Evidence & Verification
Audit and supervisory inspection by national market surveillance authorities can examine any documentation referenced above. Notified bodies inspect technical documentation, the QMS, and conformity assessment evidence where applicable.
Typical Evidence Categories
- Risk management records: register, treatment, residual risk acceptance
- Data governance records: data sheets, bias reports, dataset versioning
- Technical documentation: Annex IV file, traceability matrix
- Testing records: validation, robustness, adversarial, accuracy
- Logging exports demonstrating compliance with Article 12
- Incident register and serious-incident reports
- Post-market monitoring data and trend analyses
- FRIAs (deployers), DPIAs (where applicable)
- QMS records including audits and management review
Common Remediation Items
- Annex IV documentation not maintained current after model updates
- Risk management treated as a one-off pre-launch exercise
- Bias diagnostics absent or limited to one dimension
- Cybersecurity assessment treats AI as a black box without adversarial robustness testing
- FRIA and DPIA performed in isolation rather than coordinated

12. FAQs
When does the AI Act start to bite?
It already does. Prohibited practices have been in force since 2 February 2025. GPAI provider obligations applied from 2 August 2025. Most high-risk obligations apply from 2 August 2026, and Annex I product-embedded high-risk from 2 August 2027.
Are we a provider or a deployer?
Provider obligations attach to whoever places the system on the market or puts it into service under their own name. If you take a third-party model, substantially modify it, or rebrand it, you may become a provider. If you use a system under your authority for professional purposes, you are a deployer. A single organization can be both for different systems.
What counts as a high-risk AI system?
Annex III systems in the eight defined areas, and systems embedded in Annex I-regulated products. A system in an Annex III area is not high-risk if it does not pose a significant risk of harm under Article 6(3), but this derogation must be documented.
Do we need a Notified Body?
For most Annex III systems, no — the provider performs an internal control under Annex VI. Notified Body assessment is required for biometric identification systems and for high-risk AI embedded in Annex I products, following the relevant sectoral conformity assessment routes.
What is a Fundamental Rights Impact Assessment?
The FRIA is a deployer obligation under Article 27, mandatory for public bodies and private operators in defined Annex III contexts (notably essential public services and credit scoring). It assesses risks to fundamental rights, impacted persons, monitoring measures, and complaint mechanisms.
How does the AI Act relate to ISO 42001?
ISO 42001 is the international management system standard for AI; the AI Act is binding EU regulation. ISO 42001 certification does not equal AI Act compliance, but an ISO 42001-aligned program delivers most of the documentation and governance that the AI Act requires of providers.
How does the AI Act relate to GDPR?
GDPR continues to apply to any AI system processing personal data. Article 10(5) of the AI Act permits processing of special-category data for bias correction under strict conditions. DPIA and FRIA should be coordinated.
What about general-purpose AI models?
From 2 August 2025, GPAI providers face documentation, copyright, and transparency obligations under Chapter V. Models exceeding the Article 51 threshold (currently 10^25 cumulative training FLOPs) face additional model evaluation, adversarial testing, incident reporting, and cybersecurity obligations.
What are the penalties?
Up to €35 million or 7 percent of worldwide annual turnover for prohibited-practice violations; up to €15 million or 3 percent for most other infringements; up to €7.5 million or 1 percent for supplying incorrect information.
What about generative AI deployed inside our business?
If you use a third-party generative model (such as a foundation model API) for internal productivity, you are a deployer. Limited-risk transparency obligations under Article 50 apply (label synthetic content, inform users they are interacting with AI). High-risk obligations apply only if the deployment falls into Annex III.
How does this relate to the AI Liability Directive?
The proposed AI Liability Directive is separate civil liability legislation. The AI Act is product regulation. The two together create a fuller liability framework. The Liability Directive remains in negotiation as of 2026.
13. Summary
The EU AI Act establishes a tiered, risk-based regulatory regime for artificial intelligence with extraterritorial reach. Compliance is built on lifecycle risk management, data governance, technical documentation, logging, human oversight, accuracy and robustness, and post-market monitoring. For most providers, the practical path is to build an ISO 42001-aligned AI management system, integrate it with the existing ISMS, and use that combined evidence base to support conformity assessment under Article 43.
