Paris, on
Mr president,
I am following up on the e-mail exchanges that have taken place between the services of the Commission Nationale de l'Informatique et des Libertés (CNIL) and [REDACTED]'s data protection officer, as part of the investigation of Mr [REDACTED]'s complaint forwarded by the German Data Protection Authority of the Land of Berlin (Der Berliner Beauftragte für Datenschutz und Informationsfreiheit), in application of the mechanism for cooperation between European authorities pursuant to Articles 56 et seq. of the General Data Protection Regulation (GDPR).
As a reminder, the complainant lodged a complaint against the company [REDACTED] relating to a security and confidentiality issue in the processing of his personal data. On 19th September 2019, the complainant indicated that he had received an e-mail from [REDACTED] on his e-mail address ([REDACTED]), giving the surname, first name, telephone number and e-mail address of a third party.
In the exchanges that took place between the CNIL services and [REDACTED]'s data protection officer, by e-mails of 26th November and 18th December 2020, it was indicated that this disclosure of personal data would be the consequence of an internal human error.
It was specified that following the intervention of the CNIL services in the case of such a disclosure, [REDACTED] notified the personal data breach to the data subject.
These facts lead me to remind you that, it is your responsibility as data controller to:
- ensure compliance with Article 5(1)(a) of the DGPD, by ensuring that personal data are processed lawfully, fairly and in a transparent manner ;

- in the event of a personal data breach, to notify the CNIL of the breach without undue delay and, if possible, no later than 72 hours after having become aware of it in accordance with Article 33 of the GDPR. As part of its security obligations, the data controller shall set up a procedure to manage personal data breaches, with the aim of preventing, detecting and reacting appropriately to limit the risks and avoid future breaches.
