Sovereignty & jurisdiction of AI data

Sovereign AI: beyond the CLOUD Act

The CLOUD Act allows U.S. authorities to access the data of your AI systems hosted with U.S. providers — even when the servers are in Europe. This page explains why, how, and what regulated organizations need to do.

Key points for executives

If your AI systems process sensitive data (health, finance, legal, defense) and your cloud provider is American, your data is potentially accessible to U.S. authorities without your consent or notification. The CLOUD Act applies to communication and cloud service providers subject to U.S. jurisdiction, wherever the data is stored. It is a legal, regulatory, and reputational risk.

Impact: choice of cloud provider, compliance strategy, DORA/NIS2 exposure.

Text of the CLOUD Act (H.R. 4943), enacted in the Consolidated Appropriations Act, 2018 — U.S. Congress

Definition

Sovereign AI infrastructure

A sovereign AI infrastructure is a set of compute, storage, and data processing resources operated exclusively under European jurisdiction, with no technical or legal dependency on entities subject to the extraterritorial law of third countries (notably the U.S. CLOUD Act, FISA Section 702, or China's National Intelligence Law). It is designed so that the entire processing chain — from input data to outputs and audit trails — remains under the exclusive legal control of the European Union.

The CLOUD Act: what your cloud provider doesn't tell you

Enacted in March 2018, the CLOUD Act (Clarifying Lawful Overseas Use of Data Act) allows U.S. authorities, by warrant or court order, to require communication and cloud service providers subject to U.S. law to disclose the data they hold — regardless of the country where the data is physically stored.

In practice, if your AI system is hosted on AWS, Azure, or Google Cloud — even in a European data center — the U.S. government can lawfully request access to:

  • Your AI prompts and queries (including any personal and business data they contain)
  • The outputs produced by your AI models
  • Audit trails and decision logs
  • Training data and fine-tuned models
  • Metadata: who queries what, when, and in what context

The U.S. cloud provider is under no obligation to notify you of such an access request. It may even be prohibited from doing so (gag order).

NIS2, DORA, and the AI Act: regulatory convergence

Three European texts converge on the same requirement — control over critical digital infrastructure:

AI Act — High-risk systems

The AI Act requires traceability, documentation, and auditability of AI systems. If foreign authorities can demand audit trails through the CLOUD Act, control over them becomes harder to demonstrate. Article 15 requires robustness and cybersecurity — uncontrolled extraterritorial access is a risk to assess.

AI Act Article 15 — Accuracy, robustness and cybersecurity

DORA — Operational resilience (financial sector)

The Digital Operational Resilience Act requires financial institutions to control the risks arising from third-party ICT service providers. Cloud providers subject to the CLOUD Act represent a concentration risk and a jurisdictional risk that DORA explicitly identifies. Financial institutions must assess this risk and demonstrate that they have alternatives.

DORA Regulation — Official text

NIS2 — Network and information security

The NIS2 Directive requires securing the entire digital supply chain. A cloud provider subject to the CLOUD Act introduces an uncontrolled access vector into that chain. Essential and important entities must identify and mitigate this risk.

Why sovereignty is critical for high-risk AI systems

High-risk AI systems process your organization's most sensitive data: medical records, financial data, legal evidence, citizen data, trade secrets.

Health

Medical records processed by diagnostic AI are protected health data. Disclosing them to a foreign authority outside the cases provided for in GDPR Article 48 may breach GDPR and the French Data Protection Act (loi Informatique et Libertés).

Finance

Risk analyses, credit scoring, and fraud detection involve critical financial data. DORA requires that this data be protected against any unauthorized access.

Legal

Litigation strategies, case law analyses, and attorney-client communications processed by AI are covered by professional secrecy. The CLOUD Act does not recognize this privilege.

Public sector

Citizen data processed by government AI (benefits, taxation, security) is sovereign by nature. Exposing it to a foreign jurisdiction is unacceptable.

The KOREV approach: sovereignty by design

European hosting: data centers, subcontractors, and providers selected outside the scope of the CLOUD Act, according to the level of external dependency defined by the organization.

No data transfers outside the EU in sovereign configurations: prompts, outputs, and audit trails remain under European jurisdiction.

AI models operated in Europe: no dependency on OpenAI, Google, or Anthropic APIs for processing sensitive data.

Audit trails under customer control: decision logs belong to the customer, not the provider.

Auditable architecture: the customer can verify the entire processing chain.

Combined GDPR + AI Act + DORA + NIS2 requirements: a single infrastructure designed to make these frameworks easier to implement, depending on the system and its use.

Operational summary

Checklist: assessing the sovereignty of your AI infrastructure

The essential checks to assess how exposed your AI systems are to the CLOUD Act.

  1. 1Identify every cloud provider involved in your AI systems and check its jurisdiction (U.S. law = CLOUD Act risk).
  2. 2Map your AI data flows: where do prompts, outputs, and audit trails travel?
  3. 3Check whether your AI APIs (OpenAI, Google AI, Anthropic) involve data transfers outside the EU.
  4. 4Assess DORA compliance: does your AI cloud provider represent an ICT concentration risk?
  5. 5Assess NIS2 compliance: is your AI supply chain secured end to end?
  6. 6Document AI data protection measures for regulators (CNIL, ACPR, ANSM).
  7. 7Consider migrating high-risk systems to a sovereign AI infrastructure.
