What is digital sovereignty?

It is the ability of an organization to maintain control over its data, its processing and the infrastructure hosting them, without dependence on a foreign jurisdiction capable of imposing access to that data.

Is hosting in Europe enough to be sovereign?

Not always. If the service operator or its parent company is subject to foreign law with extraterritorial reach, data hosted in Europe may still be exposed to foreign access requests. Hosting and jurisdiction must both be aligned with the EU.

How does sovereignty relate to electronic signature?

Signature is accompanied by the signed document, personal data of signatories and audit logs. Their location and the applicable law for the provider determine who can ultimately access them — a direct issue of confidentiality and compliance.

What is the link between sovereignty and eIDAS?

eIDAS structures the European market for trust services and defines the legal value of signatures. Relying on this European framework is a pillar of a sovereign approach, complementary to the choice of hosting and jurisdiction.

Is Certyneo a sovereign solution?

Certyneo is an electronic signature solution designed in Europe and hosted in the European Union, conceived as a European alternative to actors subject to extra-European jurisdictions. The objective: keep documents, data and evidence under European law.

Sovereignty

Digital sovereignty and electronic signature

Signing a document commits your organization as much as the data it contains. But you still need to know who, ultimately, can access it. Digital sovereignty answers this question: it designates the capacity of an organization, and more broadly of a State, to maintain control of its data, its processing and the infrastructures that support them, without dependence on a foreign jurisdiction.

Legal framework

Digital sovereignty is not a slogan: it plays out at the intersection of several texts that determine, concretely, who has the right to access your signed data. The location of hosting, the nationality of the service provider and the jurisdiction it depends on often take precedence over contractual promises.

To move from theory to practice, discover the Certyneo electronic signature solution and its offer dedicated to your sector — eIDAS compliant, no installation required.

GDPR: the European regulation governs the processing of personal data and imposes strong guarantees for any transfer outside the Union, including when a European service provider relies on a non-European parent company or infrastructure.
eIDAS: the European regulation on electronic identification and trust services sets the levels of legal value of signatures (simple, advanced, qualified) and structures the European market for trust services.
Extraterritoriality: certain non-European legislations, such as the American Cloud Act, allow foreign authorities to require a service provider subject to their law to disclose data, wherever it is stored — including in Europe.
Jurisdiction and hosting: data hosted in Europe but operated by an entity subject to foreign law does not necessarily escape that law. Sovereignty requires aligning hosting, operator and jurisdiction with the European Union.

Guarantees to verify with a service provider

Data location: documents, signatures and proof logs are hosted in data centers located in the European Union, with no replication to a third country.

Operator jurisdiction: the company that operates the service and holds the keys is subject to the law of an EU Member State, with no parent company subject to extraterritorial legislation.

Subcontracting chain: hosts and technical subcontractors are also European, or otherwise clearly identified, with associated transfer guarantees.

eIDAS compliance: the service relies on signature mechanisms compliant with European regulation and documents the level of legal value achieved.

Documentary transparency: privacy policy, subprocessor register and processing location are accessible and verifiable, not merely asserted.

Reversibility and control: you can retrieve your documents and evidence in open formats, and terminate the relationship without loss or proprietary lock-in.
