SecNumCloud Ready: your data on infrastructure qualified by ANSSI
Voltn (formerly NetExplorer) is currently undergoing SecNumCloud qualification. In the meantime, the SecNumCloud Ready option hosts your data on already-qualified infrastructure, using the Voltn application environment your teams already know.

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

Data exposed to extraterritorial legislation.
A cloud provider 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 the bar.
Security, sovereignty, traceability: public buyers and major accounts are incorporating increasingly strict standards into their procurement processes. SecNumCloud is appearing more and more frequently.
The public sector and OIVs facing State policy.
Government agencies, local authorities, and operators of vital importance: the State's cloud policy directs sensitive data toward qualified offerings. It is better to be proactive than reactive.
Cyberthreats that demand the highest standards.
Ransomware, data exfiltration, targeted attacks: the more strategic the data, the more it attracts threats. Hosting standards must keep pace with the threat landscape.

FAQ
What is the current status of Voltn's qualification process?
Voltn has reached the initial milestones of the ANSSI qualification process and is proceeding step by step, with a commitment to transparency. In the meantime, the SecNumCloud Ready option currently offers hosting on qualified infrastructure.
Can I use a solution that is not SecNumCloud qualified?
Yes, provided it meets the security and compliance requirements specific to your organization or sector. Not all organizations are subject to a qualification mandate; many prefer sovereign, certified solutions tailored to their needs while keeping pace with evolving standards like SecNumCloud.
Is SecNumCloud mandatory?
No, not in most cases. However, this 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 when not mandatory, 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 that is already SecNumCloud qualified, operated by Dassault Systèmes, while maintaining the Voltn application environment. You immediately benefit from hosting that complies with the framework's requirements, without changing how you work.
Is Voltn SecNumCloud qualified?
No, not at this time. Voltn is currently in the process of obtaining ANSSI qualification. In the meantime, the 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?
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 much easier.
