What is PIA?
PIA is a free software tool published by the French data protection authority (CNIL) to help organizations achieve GDPR compliance. It guides users through the CNIL's DPIA methodology step by step, providing a knowledge base of legal requirements and protective measures, risk visualization tools, and customizable templates. The software comes in two forms: a portable Electron desktop application for Windows, macOS, and Linux that stores data locally, and a web version that can be deployed on an organization's own servers (requiring the separate pia-back Ruby on Rails backend with PostgreSQL). The tool supports 20 languages and is licensed under GPL-3.0.
