What is data breach notification?

Data breach notification is the mandatory process of reporting security incidents involving personal data to authorities and affected individuals within specific timeframes.

Data breach notification is a critical legal requirement that mandates organizations to report security incidents involving personal data to relevant supervisory authorities and, in certain cases, to affected data subjects. Under GDPR, organizations must notify the relevant supervisory authority within 72 hours of becoming aware of a breach likely to result in risk to individuals' rights and freedoms.

A notifiable breach involves unauthorized access, alteration, destruction, or disclosure of personal data. The notification must include the nature of the breach, approximate number of affected individuals, potential consequences, and measures taken to address the incident. When the breach poses high risk to individuals, direct notification to affected persons is also required.

Beyond GDPR, various jurisdictions have specific breach notification laws with different timelines and requirements. Some sectors like healthcare and finance have additional obligations. The notification serves multiple purposes: enabling regulatory oversight, allowing individuals to take protective measures, and maintaining transparency.

Effective breach response requires established incident response procedures, clear escalation paths, and pre-drafted notification templates. Organizations should conduct regular tabletop exercises to test their response capabilities and ensure compliance with multiple regulatory frameworks.
