German AI Regulation: Navigating BaFin, DORA, NIS2 and the KI-MIG
German firms deploying AI do not face one regulator or one rulebook. They face the EU AI ActRèglement (UE) 2024/1689Le règlement de l'Union européenne sur l'intelligence artificielle. Il répartit les systèmes d'IA en niveaux de risque — interdit, haut risque, risque limité et risque minimal — et attache des obligations différentes au fournisseur qui construit un système et au déployeur qui l'utilise. Il est entré en vigueur le 1er août 2024 et s'applique par étapes ; le Digital Omnibus, règlement (UE) 2026/1744, en vigueur depuis le 27 juillet 2026, a reporté les étapes relatives au haut risque sans modifier les sanctions. L'article 99 les maintient à un maximum de 35 millions d'euros ou 7 % du chiffre d'affaires annuel mondial pour les pratiques interdites, et à un maximum de 15 millions d'euros ou 3 % pour la plupart des autres manquements, y compris les obligations en matière de haut risque et de transparence.S'applique àFournisseurs et déployeurs de systèmes d'IA mis sur le marché de l'UE ou utilisés dans l'UE.Prochaine échéance2 décembre 2026 — Marquage des contenus générés par l'IA au titre de l'article 50, paragraphe 2, pour les systèmes déjà sur le marché au 2 août 2026Lire le texte source (s'ouvre dans un nouvel onglet)Information générale sur l'instrument cité, ne constituant pas un conseil juridique. as implemented domestically through the KI-MIGKI-Marktüberwachungs- und Innovationsförderungsgesetz — loi allemande de mise en œuvre de l'EU AI ActLa loi allemande qui transpose l'EU AI Act en droit national, en vigueur depuis le 29 juillet 2026.

These regimes overlap in scope, differ in deadline, and — critically — differ in who you report to and how fast.

In brief
Four regimes govern AI in German financial and critical-infrastructure firms. The KI-MIG implements the EU AI Act domestically and designates the Bundesnetzagentur as market surveillance authority. BaFin continues to supervise institutions through MaRisk and BAIT, which already require model governance and outsourcing controls that predate the AI Act. DORA governs ICT risk and third-party dependency for financial entities. NIS2, transposed through the BSIG, imposes a 24-hour early warning, a 72-hour incident notification and a one-month final report. The reporting clocks are the sharpest edge: they differ per regime, they start on awareness rather than on confirmation, and a single AI-related outage can trigger more than one at once. Build one control set and map it to all four rather than running four projects.
The four regimes, and what each one actually wants
| Regime | Scope | Core demand | Authority |
|---|---|---|---|
| KI-MIG / EU AI Act | Any AI system by use case | Risk classification, Annex IV documentation, oversight, monitoring | BNetzA as market surveillance |
| MaRisk / BAIT | Supervised institutions | Model governance, validation, outsourcing control, IT organisation | BaFin |
| DORA | Financial entities and their ICT providers | ICT risk management, third-party register, resilience testing | BaFin / ESAs |
| NIS2 / BSIGDirective (UE) 2022/2555, transposée en Allemagne par la loi de mise en œuvre de NIS 2 modifiant le BSI-GesetzLa deuxième directive de l'UE sur la sécurité des réseaux et de l'information, et la loi allemande qui la transpose en droit national. Elle fixe des mesures de gestion des risques de cybersécurité, un calendrier échelonné de déclaration des incidents et un enregistrement auprès du BSI. Au titre du § 38 Abs. 2 BSIG, la direction d'une entreprise est personnellement responsable envers l'entité en cas de manquement à ces obligations, ce qui la distingue du droit allemand antérieur en matière de sécurité informatique.S'applique àLes entités « importantes » et « particulièrement importantes » de 18 secteurs, dimensionnées selon les effectifs et le chiffre d'affaires.Lire le texte source (s'ouvre dans un nouvel onglet)Information générale sur l'instrument cité, ne constituant pas un conseil juridique. | Essential and important entities | Cyber risk measures and staged incident reporting | BSI |
The useful observation is that these ask for the same underlying artefacts in different vocabularies. An inventory of AI systems, an owner per system, a documented risk assessment, evidence of monitoring, and an incident procedure will carry a very large share of all four. Firms that run four separate programmes produce four inconsistent answers about the same system, which is worse than one imperfect answer.
The KI-MIG: what German implementation adds
The AI Act is a regulation, so it applies directly — the KI-MIG does not restate it. What national implementation supplies is the machinery: which authority conducts market surveillance, how penalties are administered, and how the AI Act’s supervision meshes with existing sectoral supervisors. For financial institutions the practical consequence is that BaFin supervision does not displace AI Act market surveillance. You should expect to evidence the same model to two audiences with different questions.
Where the reporting clocks collide
This is the part that catches firms out, because the regimes measure time differently and the trigger is usually awareness, not confirmation.
| Trigger | Regime | Clock |
|---|---|---|
| Significant cyber incident | NIS2 / BSIG | 24h early warning → 72h notification → 1 month final report |
| Major ICT-related incident | DORA | Initial, intermediate and final reports on defined deadlines |
| Serious incident involving a high-risk AI system | EU AI Act Article 73 | Reporting to market surveillance, with a shortened window for widespread infringement or serious disruption |
A single event — say, a compromised model-serving endpoint producing discriminatory credit decisions — can plausibly trigger all three. If your incident runbook names only one regulator, it is not a runbook. The remedy is unglamorous: one incident register, one clock started on first awareness, and a mapping that fans out to each recipient.
Case scenario: a fintech that thought DORA covered it
A Frankfurt payments firm completed a substantial DORA programme in 2025 — ICT risk framework, third-party register, resilience testing. Asked in a 2026 procurement round for its EU AI Act position, it had none, and discovered three things: its fraud-scoring model was arguably Annex III, its DORA third-party register listed the model vendor as an ICT provider but recorded nothing about model behaviour, and its AI literacy obligation under Article 4 had been live for over a year with no training delivered.
Nothing in its DORA work was wasted — the third-party register was two-thirds of an AI vendor inventory. But DORA asks whether a supplier can keep running; the AI Act asks whether its output is lawful, documented and monitored. Different question, same supplier.
Practical sequencing for German firms
- Build one AI inventory and make it serve the AI Act classification, the DORA third-party register and BaFin outsourcing records simultaneously.
- Close the already-enforceable AI Act duties first — Article 5 prohibitions, Article 4 AI literacy, Article 50 transparency. These are live now, unlike the high-risk tier which moved to December 2027.
- Consolidate incident reporting into a single intake with a mapping to BSI, BaFin and market surveillance, and start the clock on awareness.
- Reuse MaRisk and BAIT model governance rather than rebuilding. Validation, approval and change control already exist in supervised institutions; the AI Act mostly asks for them to be evidenced differently.
- Assign one accountable owner across all four. Splitting AI Act ownership from ICT risk ownership is how the same system ends up described two ways.
Four regimes, one estate — can you evidence the same system to all of them?
Map your AI systems against the AI Act, DORA and NIS2 in one place.

Frequently asked questions
Does the KI-MIG create obligations beyond the EU AI Act?
The AI Act applies directly as a regulation, so the KI-MIG’s role is largely institutional — designating market surveillance (the Bundesnetzagentur), administering penalties, and coordinating with sectoral supervisors. Your substantive duties come from the AI Act itself.
If BaFin already supervises our models, is the AI Act duplicated work?
There is real overlap in substance but not in evidence. MaRisk and BAIT model governance gives you validation, approval and change control; the AI Act asks for Annex IV documentation, classification reasoning, and post-market monitoring records. Treat the BaFin work as an input rather than a substitute.
Which incident clock starts first?
In practice the NIS2 24-hour early warning is the tightest, and it starts on becoming aware of a significant incident — not on completing triage. Firms should assume the shortest applicable clock and de-escalate later if a regime turns out not to apply.
Does DORA’s third-party register satisfy AI vendor documentation?
Partly. It identifies the supplier and the dependency, which is most of an AI vendor inventory. It does not record intended purpose, training data provenance, risk classification or monitoring, which the AI Act requires.
We are not a financial entity. Does any of this apply?
The AI Act does, because it regulates by use case rather than sector — employment screening and essential-services eligibility are Annex III wherever they occur. NIS2 may also apply if you are an essential or important entity. DORA and BaFin expectations will not.
