Regulation (EU) 2024/1689

The EU AI Act, explained for security teams.

The world's first comprehensive AI law takes a risk-based, product-safety approach: the higher the risk an AI use poses to health, safety, and fundamental rights, the stricter the obligations. This is a plain-English walkthrough of the risk tiers, the key articles, GPAI duties, the compliance timeline, and the penalties — the same sources our reports map your findings against.

Overview

What the AI Act is, and why it exists

The EU Artificial Intelligence Act (Regulation (EU) 2024/1689) is the first comprehensive, horizontal law governing artificial intelligence. It was published in the Official Journal on 12 July 2024 and entered into force on 1 August 2024. As a Regulation, it is directly applicable in all 27 Member States without national transposition.

Its goals are to ensure AI placed on the EU market is safe and respects fundamental rights, to give businesses legal certainty, to strengthen governance and enforcement, and to prevent a fragmented single market. The core design idea is a risk-based, product-safety approach: the Act regulates uses of AI by the risk they pose — from outright bans, through a heavy conformity regime for "high-risk" uses, down to light transparency duties and, for most systems, nothing mandatory at all.

The "Brussels effect."

Like the GDPR, the Act reaches beyond the EU. It applies to providers and deployers outside the EU wherever an AI system's output is used in the EU, so most global vendors align to it. It sits alongside — and does not replace — the GDPR, sector safety law, and cybersecurity law such as NIS2 and the Cyber Resilience Act.

Scope

What is covered — and who

An "AI system" (Art. 3(1)) is a machine-based system that operates with some autonomy, may adapt after deployment, and infers from its inputs how to generate outputs — predictions, content, recommendations, or decisions — that influence physical or virtual environments. Simple deterministic, rules-based software generally falls outside this definition.

The Act assigns duties by role: providers (who build/brand and place AI on the market), deployers (who use it professionally), importers, and distributors. Most organizations are deployers. A crucial twist under Article 25/26: a deployer can become a provider if it puts its own name on a high-risk system, substantially modifies one, or repurposes a system so it becomes high-risk.

Exclusions. The Act does not apply to AI used exclusively for military/defence/national-security purposes, to systems developed and used solely for scientific R&D, to pure pre-market research and testing, or to purely personal non-professional use. Free and open-source AI is largely exempt unless it is a prohibited practice, a high-risk system, or a GPAI model.

Classification

The four risk tiers

The Act sorts AI uses into four bands. Most systems fall in the bottom tier and carry no mandatory obligation.

Tier 1 · Unacceptable

Prohibited (Art. 5)

Banned outright since 2 Feb 2025.

Examples: social scoring, manipulative/subliminal techniques, untargeted facial-image scraping, emotion inference at work or school, most real-time public biometric identification.

Tier 2 · High risk

Full obligations (Art. 8–27)

Annex I safety components + Annex III use cases.

Examples: CV-screening & recruitment, credit scoring, insurance pricing, biometrics, critical-infrastructure safety, education assessment, law enforcement.

Tier 3 · Limited risk

Transparency (Art. 50)

Disclosure duties, not the full regime.

Examples: chatbots (tell users it's AI), deepfakes and synthetic media (label/mark), emotion-recognition notice.

Tier 4 · Minimal risk

No mandatory duty

The vast majority of systems.

Examples: spam filters, AI in games, recommenders, inventory optimization, grammar assistants. Voluntary codes encouraged.

One duty spans all tiers.

AI literacy (Art. 4) — providers and deployers must take measures to support AI literacy among staff who build or use AI (the Digital Omnibus softened the earlier duty to "ensure" a sufficient level) — applies to every provider and deployer, regardless of risk tier, since 2 Feb 2025.

Foundation models

General-purpose AI (GPAI) & systemic-risk models

GPAI models are a separate, cross-cutting category (Title V) layered on top of the four tiers. A general-purpose AI model shows significant generality and can perform a wide range of distinct tasks — the foundation/large language models behind today's chatbots and coding assistants. There are two levels of obligation:

All GPAI models — Article 53: maintain technical documentation, inform downstream integrators, adopt an EU copyright/TDM-opt-out policy, and publish a summary of training content. Open-source GPAI is exempt from some documentation duties unless it has systemic risk.
GPAI with systemic risk — Article 55: additional duties triggered when training compute exceeds 10²⁵ FLOP (presumption) or by Commission designation — model evaluation, adversarial testing (red-teaming), systemic-risk mitigation, serious-incident reporting to the AI Office, and model-level cybersecurity.

A voluntary GPAI Code of Practice, facilitated by the AI Office and published in 2025, offers a presumption-of-conformity route while harmonised standards are developed. GPAI obligations have applied since 2 August 2025; the Commission's enforcement powers over GPAI providers apply from 2 August 2026.

The key articles, explained

Each article below carries an anchor id so Araghatta reports can deep-link straight to the obligation behind a finding.

Art. 5

Prohibited AI practices

All actors

Bans AI uses judged to pose unacceptable risk, applicable since 2 Feb 2025. The list covers subliminal/manipulative techniques that cause harm; exploitation of vulnerabilities (age, disability, social/economic situation); social scoring; individual crime-risk prediction from profiling alone; untargeted scraping of facial images; emotion recognition in the workplace and schools; biometric categorization inferring sensitive attributes; and — with narrow, authorized law-enforcement exceptions — real-time remote biometric identification in public spaces. The Digital Omnibus adds a prohibition on AI that generates non-consensual intimate imagery or child sexual abuse material, with a transition to 2 Dec 2026.

Art. 9

Risk-management system

Provider · high-risk

Requires a continuous, iterative risk-management system across the entire lifecycle of a high-risk system: identify known and foreseeable risks; estimate risk under intended use and reasonably foreseeable misuse; evaluate post-market data; and adopt targeted risk-control measures. Residual risks must be judged acceptable, and the system must be tested against defined metrics before deployment and throughout development, with special attention to children and vulnerable groups.

Art. 10

Data and data governance

Provider · high-risk

Training, validation, and testing datasets must meet quality criteria and be governed for origin, preparation, assumptions, suitability, and examination for biases affecting health, safety, or rights. Datasets should be relevant, sufficiently representative, and as far as possible free of errors and complete for the intended purpose. Limited processing of special-category data is permitted strictly for bias detection and correction, with safeguards.

Art. 12

Record-keeping (logging)

Provider · Deployer

High-risk systems must automatically log events over their lifetime, to a degree appropriate to their purpose, to ensure traceability, support post-market monitoring (Art. 72), and flag situations that may present a risk or a substantial modification. Deployers must keep the logs (generally at least six months). Minimum log content is specified for certain biometric systems.

Art. 13

Transparency & instructions to deployers

Provider · high-risk

High-risk systems must be sufficiently transparent for deployers to interpret and use output appropriately, and must ship with instructions for use covering the provider's identity, intended purpose, performance and known limitations, human-oversight measures, expected lifetime, and maintenance. (Distinct from Art. 50, which is transparency to end users.)

Art. 14

Human oversight

Provider · Deployer

High-risk systems must be designed so humans can effectively oversee them in use — understanding capabilities and limits, staying alert to automation bias, correctly interpreting output, deciding not to use or to override, and being able to intervene or stop the system. For certain biometric identification, a "four-eyes" principle (verification by two competent people) applies.

Art. 50

Transparency to users & synthetic content

Provider · Deployer

Applies from 2 Aug 2026: chatbots must tell people they are dealing with an AI; generative-AI output must be marked in a machine-readable format as artificially generated; deployers must disclose deepfakes and AI-generated public-interest text; and people exposed to emotion-recognition or biometric-categorisation systems must be informed. Under the Digital Omnibus, generative systems already on the market before 2 Aug 2026 have a grace period to 2 Dec 2026 for the machine-readable marking (watermarking) duty.

Art. 53

GPAI provider obligations

GPAI provider

Baseline duties for all general-purpose AI model providers: maintain up-to-date technical documentation (training/testing and evaluation); provide documentation to downstream providers; adopt a policy to comply with EU copyright law including honouring TDM opt-outs; and publish a sufficiently detailed summary of training content per the AI Office template. Open-source GPAI gets relief from some documentation duties (not the copyright and training-summary duties).

Art. 55

GPAI systemic-risk obligations

GPAI · systemic

Additional duties for GPAI models with systemic risk (≥10²⁵ FLOP or Commission designation): perform model evaluation with standardized protocols and adversarial testing (red-teaming); assess and mitigate systemic risks and their sources; track, document, and report serious incidents to the AI Office without undue delay; and ensure an adequate level of cybersecurity for the model and its physical infrastructure. Scope: these duties fall on the provider of the systemic-risk model, not on an enterprise that merely deploys or integrates it (deployers rely on the provider's Art. 53 documentation); an organization that substantially modifies or builds such a model should assess with counsel whether it has become a provider.

Art. 72

Post-market monitoring

Provider · high-risk

Providers must establish a post-market monitoring system proportionate to the system's risks, actively and systematically collecting, documenting, and analyzing performance data over the lifetime — feeding back into the Art. 9 risk process. Serious incidents are separately reportable under Art. 73.

Art. 25 & 26

Deployer obligations (& becoming a provider)

Deployer

Art. 26 sets deployer duties for high-risk systems: use the system per the provider's instructions, assign competent human oversight, ensure input data is relevant, keep logs, inform affected workers and persons, and cooperate with authorities. Art. 25 is the trap: put your name on a high-risk system, substantially modify it, or change its intended purpose so it becomes high-risk, and you inherit the full provider obligation set.

Annexes

Annex III & Annex IV

Annex III — high-risk use cases

Lists the domains that make a stand-alone AI system high-risk (subject to the Art. 6(3) "no significant risk" filter):

Biometrics — remote identification, sensitive-attribute categorization, emotion recognition.
Critical infrastructure — safety components for traffic, water, gas, heating, electricity, digital infrastructure.
Education & vocational training — admissions, learning-outcome evaluation, exam monitoring.
Employment — recruitment/selection (CV screening, ranking), promotion, termination, task allocation, performance monitoring.
Essential private & public services — benefits eligibility, creditworthiness/credit scoring, life & health insurance risk & pricing, emergency triage.
Law enforcement — risk assessment, polygraph-type tools, evidence-reliability evaluation, profiling.
Migration, asylum & border control — risk assessment, application examination.
Administration of justice & democratic processes — assisting judicial authorities; influencing elections/voting.

Annex IV — technical documentation

Specifies the contents of the technical-documentation file a high-risk provider must compile and keep current: a general description and intended purpose; design specifications, architecture, and development process; data requirements and datasets; human-oversight measures; validation/testing procedures and metrics (accuracy, robustness, cybersecurity, bias results); the risk-management system; lifecycle changes; and the EU declaration of conformity. This is the evidence file behind the CE marking.

Duties

Obligations by role

If you build or brand the AI, you're a provider and carry most obligations. If you use AI from someone else, you're a deployer. Watch Art. 25 for role flips.

Enforcement

Penalties

Fines are capped at the higher of a fixed amount or a percentage of total worldwide annual turnover (for SMEs/start-ups, the lower). National authorities enforce most breaches; the Commission's AI Office enforces GPAI directly.

Breach	Maximum fine
Prohibited practices (Art. 5)	€35M or 7% of global annual turnover
Most other obligations (high-risk, transparency, provider/deployer duties)	€15M or 3% of global annual turnover
Incorrect/misleading information to authorities	€7.5M or 1% of global annual turnover
GPAI providers (Commission-enforced)	€15M or 3% of global annual turnover

Practical

How to comply — a working checklist

Inventory & classify. Build a live inventory of every AI system — sanctioned and shadow — and record your role and each system's intended purpose. Screen against Art. 5, Annex I/III, Art. 50, and the GPAI definition.
Cover what's already in force. Confirm no prohibited practices; stand up an AI-literacy program (Art. 4).
For each high-risk system (Annex III by 2 Dec 2027; Annex I by 2 Aug 2028). Establish the Art. 9 risk-management system, evidence Art. 10 data governance, compile Annex IV docs, enable Art. 12 logging, provide Art. 13 instructions and Art. 14 oversight, meet Art. 15 accuracy/robustness/cybersecurity, run the Art. 43 conformity assessment, draw up the Art. 47 declaration, affix CE marking, and register (Art. 71).
For limited-risk (by 2 Aug 2026). Add AI-disclosure to chatbots; mark synthetic content and label deepfakes (Art. 50; marking grace to 2 Dec 2026 for systems already on the market).
If you provide/self-host GPAI (now in force). Maintain Art. 53 documentation, copyright/TDM policy, and a training-content summary; add Art. 55 controls if systemic-risk.
Govern continuously. Monitor for re-tiering, retain evidence, rehearse incident reporting, and map controls to NIST AI RMF, ISO/IEC 42001, and the OWASP LLM Top 10 to reuse evidence.

Where Araghatta fits.

Sargha produces the inventory and the evidence behind Art. 10, 14 and 15, which it maps automatically, and Art. 4 literacy in the risk register. Other obligations, such as Art. 9, Art. 26 (deployer), Art. 50 and Annex IV, can be referenced manually; Art. 55 applies to providers of systemic-risk GPAI models, not to ordinary deployers. Roadmap Automatic mapping for Art. 6, 9, 11, 12, 26, 50, 55 and 72 is planned.
