Personal Data Breach Notification

GDPR requirement to notify the supervisory authority within 72 hours and affected individuals when risk is high.

Definition

Controllers must notify the supervisory authority without undue delay and, where feasible, within 72 hours of becoming aware of a personal data breach unless it is unlikely to result in risk. If the breach is likely to result in high risk, data subjects must be informed without undue delay. All breaches must be documented internally regardless of notification.

Example

A lost unencrypted laptop with customer data triggers authority notification within 72 hours.

Exam tip

Encryption that renders data unintelligible can remove the need to notify individuals.
