Data-Breach Reporting Duties: Overview
Data-breach reporting duties are legal obligations requiring organizations to notify regulatory authorities—and sometimes affected individuals—when personal or sensitive data has been compromised. These duties are intended to:
Protect Data Subjects – Allow timely remedial action (e.g., changing passwords, freezing accounts).
Ensure Regulatory Oversight – Authorities can investigate and prevent further breaches.
Promote Accountability – Organizations maintain proper security controls and incident response mechanisms.
These duties exist under frameworks such as:
EU GDPR (Articles 33–34)
UK Data Protection Act 2018
U.S. state laws (e.g., California Consumer Privacy Act, various state breach notification laws)
Australia Privacy Act, APP 11.1
Key Legal Requirements
Timely Notification
GDPR: Notify the supervisory authority within 72 hours of discovering a breach.
U.S. states vary, generally 30–90 days.
Content of Notification
Nature of the breach (types of data compromised)
Likely consequences for individuals
Measures taken or proposed to mitigate risk
Notification to Data Subjects
Required if breach is likely to result in high risk to rights and freedoms.
Must be in clear and plain language.
Recordkeeping
Maintain internal documentation of breaches, even if not reportable, including cause and remedial actions.
Cross-Border Notification
If personal data is transferred internationally, supervisory authorities in affected jurisdictions may need to be informed.
