A data breach is when personal details fall into the hands of third parties who should not have access to this information. Instances where a breach cannot be ruled out are also considered data breaches. Destroying personal details or rendering them unusable also constitutes a data breach. A data breach is always the result of a security incident and can occur by accident or deliberately. A security incident leads to a data breach if it involves personal data.

A data breach implies a violation of the General Data Protection Regulation (AVG). These violations carry high administrative fines.
