[ 3DS Outscale ]
Designing your critical platforms on the SecNumCloud-certified sovereign cloud
SecNumCloud
Building your architectures on a cloud certified by ANSSI
3DS Outscale is one of the very few cloud providers to hold SecNumCloud certification across its entire range of services, operating exclusively under French jurisdiction. In the healthcare, defence, public sector and regulated industry sectors, ANSSI certification is non-negotiable.
AWS compatibility
Migrating from AWS without rewriting your architecture
The Outscale API is largely compatible with that of AWS. Workloads designed using Terraform for AWS can be adapted for Outscale with a reasonable amount of effort. Complying with sovereignty requirements does not mean everything has to be rewritten.
Backed by Dassault Systèmes
Working with a leading French industrial player
3DS Outscale is a subsidiary of Dassault Systèmes, a leading French industrial firm. This affiliation ensures technological independence and financial stability in line with long-term sovereignty objectives.
The cornerstones of our 3DS Outscale expertise
- SecNumCloud certification and ANSSI compliance
3DS Outscale has been awarded SecNumCloud certification across its entire range of services. We design and support architectural solutions through to certification, with a particular focus on the healthcare, public sector and defence sectors.
Discover our cybersecurity expertise - AWS API compatibility and sovereign migrations
The Outscale API is compatible with AWS across a wide range of services. For customers already using AWS who are subject to data sovereignty requirements, this makes migration much easier. Terraform and OpenTofu infrastructure can be adjusted with a degree of effort.
- Hosting of sensitive data and HDS
When it comes to healthcare data, the combination of HDS and SecNumCloud certification makes 3DS Outscale a leading choice. We build architectures that comply with the GDPR and HDS, taking into account the technical trade-offs this entails in terms of encryption, traceability and data residency.
- Networking, security and hardening
We implement networking, security and hardening measures that comply with SecNumCloud requirements, incorporating the DevSecOps practices we apply to other cloud platforms. Compliance is an operational discipline.

Cloud sovereignty has become as much a technical and operational debate as a political one. For the vast majority of critical workloads, Scaleway is more than adequate. However, in the most sensitive sectors (highly regulated healthcare, defence, certain public or industrial sectors), SecNumCloud certification is becoming a legal or contractual requirement.
In these contexts, 3DS Outscale makes perfect sense. Our close links enable us to offer a comprehensive service: Scaleway for the majority of sovereign workloads, Outscale for scenarios requiring scrupulous ANSSI certification.

Not all projects require SecNumCloud. But when regulations require it, it is better to be prepared from the design stage than to have to start all over again later on.
