🇪🇺GDPR Art34Rule: GDPR-Art-034high

Communication of Personal Data Breach to the Data Subject

Description

When a personal data breach is likely to result in high risk to data subjects, the controller shall communicate the breach to data subjects without undue delay.

⚠️ Risk Impact

Subject notification is required when 'high risk' to rights/freedoms. Risk assessment must be documented; defaulting to non-notification without documentation produces enforcement.

EchelonGraph's Tier 1 Cloud Scanner automatically checks for this condition across all connected cloud accounts. Violations are flagged as high-severity findings with remediation guidance.

🔧 Remediation

Risk-of-harm assessment per breach. Templates for subject notification. Mass-notification capability. Document rationale for non-notification when applicable.

💀 Real-World Attack Scenario

A company experienced a breach affecting 2M EU users. Risk assessment determined 'low harm' due to encryption — but assessment wasn't documented. DPA disagreed with the determination + ordered full notification + €4.5M fine for late + insufficient notification.

💰 Cost of Non-Compliance

Article 34 violations: up to €10M / 2% revenue.
