SecNumCloud qualification: a French priority
For the most sensitive data, standard compliance is no longer enough. The market is aligning with the French government's most demanding standard.

Data exposed to extraterritorial legislation.
A cloud subject to the Cloud Act or equivalent laws may be compelled to hand over data, even if it is hosted in Europe. For sensitive data, this possibility alone is a risk.
Tenders that are raising their requirements.
Security, sovereignty, and traceability: public buyers and major accounts are incorporating increasingly strict standards into their procurement processes. SecNumCloud is appearing there more and more frequently.
The public sector and OIVs facing the State's doctrine.
Government agencies, local authorities, and operators of vital importance: the State's cloud doctrine directs sensitive data toward qualified offerings. Prevention is better than cure.
Cyber threats that demand the highest standards.
Ransomware, data exfiltration, targeted attacks: the more strategic the data, the more it attracts threats. The level of hosting security must match the level of the threat.

What is SecNumCloud?
Description
SecNumCloud qualification is issued by ANSSI, the French National Cybersecurity Agency, following an in-depth audit of the provider and its infrastructure. It certifies that a cloud service meets the highest French standards for security, sovereignty, and data protection.
Usage
The benchmark for assessing the reliability of a cloud service.

Description
Data hosted and processed in France or Europe, a provider protected from extraterritorial legislation such as the Cloud Act, strictly controlled and traceable access, and infrastructure that meets enhanced cybersecurity standards.
Usage
Protecting sensitive data to the highest standards in the French market.

Description
Public administrations, operators of vital importance (OIVs), and companies handling sensitive data are gradually adopting SecNumCloud as their standard. It is also becoming an evaluation criterion in an increasing number of calls for tenders.
Usage
Anticipating the requirements of public procurement and critical sectors.

FAQ
What is the current status of Voltn's qualification process?
Voltn has reached the initial milestones of the ANSSI qualification process and is continuing the procedure step by step, with a commitment to transparency. In the meantime, the SecNumCloud Ready option currently offers hosting on qualified infrastructure.
Can a non-SecNumCloud qualified solution be used?
Yes, provided it meets the security and compliance requirements specific to the organization or its sector. Not all entities are subject to a qualification mandate; many prioritize sovereign, certified solutions tailored to their needs while monitoring the evolution of standards like SecNumCloud.
Is SecNumCloud mandatory?
No, not in most cases. However, the qualification may be required for certain organizations, particularly in the public sector, for operators of vital importance, or as part of tenders with high security requirements. Even without a mandate, SecNumCloud is gradually becoming a benchmark standard.
What is the difference between SecNumCloud and ISO 27001?
ISO 27001 is an international standard that certifies an information security management system based on risk management. The SecNumCloud qualification, issued by ANSSI, goes further: it imposes specific requirements for the cloud, particularly regarding sovereignty, protection against extraterritorial laws, and access security. ISO 27001 provides a foundation, while SecNumCloud represents a higher level of requirements for sensitive cloud services.
What is the SecNumCloud Ready option?
It hosts your data on infrastructure already qualified as SecNumCloud, operated by Dassault Systèmes, while maintaining the Voltn application environment. You immediately benefit from hosting that meets the standard's requirements, without changing your workflows.
Is Voltn SecNumCloud qualified?
No, not at this time. Voltn is currently undergoing the qualification process with ANSSI. In the meantime, our SecNumCloud Ready option allows you to host your data immediately on infrastructure that is already SecNumCloud qualified.
Who issues the SecNumCloud qualification?
ANSSI, the National Cybersecurity Agency of France, following an in-depth audit of the provider and its infrastructure.
What is SecNumCloud?
The SecNumCloud qualification is issued by ANSSI and guarantees that a cloud service meets high standards for security, sovereignty, and data protection. It specifically mandates strict access control, protection against extraterritorial laws, and data hosting under European jurisdiction.

But let's be honest, our cloud-based file storage and sharing solution is just easier.
