GDPR Article 33 breach notification
A controller must notify the supervisory authority of a personal-data breach without undue delay and within 72 hours of becoming aware, unless the breach is unlikely to risk individuals' rights. The notification must state the nature, categories and rough number affected, likely consequences, and measures taken; a late filing must carry reasons for the delay.
