Reviewed byCybersecurity entrepreneur & security researcher

What is Data Protection Impact Assessment (DPIA)?

Data Protection Impact Assessment (DPIA)A structured assessment, required by GDPR Article 35, that identifies and mitigates risks to individuals' rights and freedoms before high-risk personal data processing begins.


A Data Protection Impact Assessment (DPIA) is a process required by Article 35 of the EU GDPR (and equivalent provisions in the UK GDPR, Brazilian LGPD, and other privacy laws) when processing is likely to result in a high risk to the rights and freedoms of natural persons. The controller documents the nature, scope, context, and purposes of processing; assesses necessity and proportionality; analyzes risks to data subjects; and defines mitigating measures. Triggers include systematic monitoring, large-scale special-category data, and automated decisions with legal effects. If residual risks remain high, the controller must consult the supervisory authority before processing. DPIAs are also widely used as best practice outside GDPR jurisdictions.
