Digital Sovereignty

What exactly is the sovereign cloud?

A sovereign cloud hosts and manages your data under French or European law, without direct exposure to the U.S. Cloud Act. Ohmycad operates this service on the Outscale Dassault Systèmes cloud, in the France region, with a SecNumCloud option for cases where certification is required.

Data from France

Hébergées sur le cloud Outscale Dassault Systèmes, région France.

Opérateur français

Outscale, filiale de Dassault Systèmes, n'est pas soumis au Cloud Act.

SecNumCloud en option

La qualification de l'ANSSI, activée quand votre secteur l'exige.

Three terms, three definitions.

Sovereign Cloud

Infrastructure under French or European jurisdiction.

Trusted Cloud

The certification resulting from the 2021 «cloud-first» doctrine: the SecNumCloud certification, plus immunity from extraterritorial laws. Since version 3.2 of the standard, this immunity has been an integral part of SecNumCloud itself.

Extraterritoriality

The Cloud Act: What Does It Mean in Practice?

The U.S. Cloud Act allows U.S. authorities to request access to data held by a U.S. company, regardless of the country where that data is stored. Hosting data with a provider subject to French law eliminates this direct exposure.

The European Data Governance Act complements this regulation on the EU side.

Customer Reviews

They explain it better than we do

Mohammad Aghababa a year ago

I had a great technical support session with Alan and Léo from Ohmycad. They explained clearly how to save files on 3DEXPERIENCE and manage revisions with the maturity cycle. The session was very helpful, professional, and easy to follow. Looking forward to the next one on automating the drawing title block. Highly recommend their support team!

Frequently asked Questions

Frequently Asked Questions About Sovereignty

Is SecNumCloud required?

No, it is still optional and is enabled at the request of the end customer or as required by regulations.

Is it cheaper than an American hyperscaler?

Not always. The price depends on the scope and is compared to the cost estimate, line by line. What you’re purchasing first and foremost is the right to use your data and the right to operate in France.

Ohmycad, as part of our managed services, and Outscale as our hosting provider. No third parties outside of this framework.
