Hosting health data without HDS certification: what are the risks?
Hosting health data without HDS certification exposes your organization to legal risks and erodes trust. At Voltn, compliance is not an option: it is the starting point.

A legal obligation that is often overlooked or poorly anticipated.
Any organization that hosts or processes personal health data must use an HDS-certified provider. Ignoring this requirement creates a risk of non-compliance.
Shared encryption, uncertain privacy.
Without a dedicated encryption key, the confidentiality of medical records also depends on the security of other clients hosted on the same server.
Insufficient traceability for audits.
Without comprehensive logging of access and actions, proving compliance during an audit becomes complex.
Dependency on providers subject to foreign laws.
Hosting outside of Europe may expose your health data to the Cloud Act or other extraterritorial legislation.

FAQ
What is the difference between HDS certification and the ISO 27001 standard?
ISO 27001 provides a general framework for information security. HDS is a specific, mandatory certification for hosting health data in France, which is based on ISO 27001 requirements reinforced by the ANS framework.
Can HDS data be accessed from a mobile device?
Yes. The Voltn mobile app is compatible with the HDS option, in accordance with the access rights defined by your administrator.
How do I activate the HDS option?
Activation is handled by a Voltn expert. It involves an HDS contract and the setup of a dedicated infrastructure, including the generation of your own unique encryption key.
Does the HDS option change the daily use of Voltn Share and Voltn Workspace?
No. The HDS option is fully compatible with existing features: co-editing, versioning, secure links, mobile access, and synchronization. Only the hosting environment changes.
Where is data hosted with Voltn HDS?
Data is hosted exclusively in France, in HDS-certified datacenters that meet Tier 3+ or Tier 4 standards, and is outside the scope of the Cloud Act.
What is an organization-specific encryption key?
It is an encryption key generated exclusively for one organization, which ensures strict separation between environments and prevents any cross-access to another client's data.
Who is subject to the HDS hosting requirement?
Any organization that hosts or subcontracts the hosting of health data collected in the context of prevention, diagnosis, care, or medico-social monitoring activities: healthcare facilities, laboratories, private practitioners, mutual insurance companies, and supervisory bodies.
What is HDS certification?
HDS (Health Data Hosting) is the French certification governing the hosting of personal health data. Any entity hosting such data on behalf of third parties must be certified, and any organization outsourcing this data must use a certified host. The framework is published by the Digital Health Agency (ANS).
