# \[FR] How to notify the CNIL in the event of a data breach?

In the event of a data breach, we recommend that you notify the CNIL as soon as possible.

1. Go to the [CNIL website](https://notifications.cnil.fr/notifications/violation);
2. Select "Initial notification". You can return to your notification as you gather more information:

   :warning: The contact person is sometimes different from the legal representative. If it is the same person, you must still complete both sections:<br>

4\. On this page, you will need to provide as much detail as possible, even if it is only the initial notification.<br>

{% hint style="info" %}
As a reminder, you can come back to these items once you have the missing information.\
\
If you are unable to fill in all the relevant sections at this stage, we recommend that you only fill in the ones you know and come back to them later.
{% endhint %}

5. With regard to the potential consequences, you should indicate your interpretation of the situation. You can adapt this as the situation evolves and based on feedback from the CNIL.<br>

7. Once you have validated this step, you will receive confirmation of your notification by email. You will be offered the option to download a PDF version of this notification. We recommend that you download it while you wait to receive the email, as this PDF will not be sent:
