Health data hosting (HDS) must be carried out under security conditions appropriate to the data's criticality.

Getting started

Any natural or legal person who hosts health data on behalf of the persons who produced or collected the data, or on behalf of the patients themselves, must have the necessary and sufficient characteristics to guarantee the security of the data, and in particular its confidentiality

The health data in question are personal health details collected in the course of health care or social care

A certificate of compliance, called an HDS certificate, issued by certification bodies attests to the hosting companies’ compliance with the security requirements defined in the HDS standard.

This control is done in the spirit of the GDPR.

In practice

Consult the list of HDS-certified hosts, and select one that meets your needs

When ?

When you are going to process real personal health data, it will be necessary to have an operational "HDS"-certified host
