Madis is a web application that public bodies use to manage their compliance with the GDPR. Users keep registers of processing activities, processors, data-subject requests and data breaches, measure their maturity level and document their compliance. A single installation can serve several hundred independent organisations, each with its own scoped environment; accounts for data protection officers give an overview across several organisations.
Madis was designed by Soluris, a French open joint syndicate (syndicat mixte ouvert) providing digital services to local authorities, with its seat in Saintes. The code is published under the AGPL-3.0 licence on the Adullact forge and the project is actively updated, with version 2.6 in October 2026. The application is installed on your own web server and used through a browser, so the registers and documentation stay on the organisation's own infrastructure. Madis is listed in the French government's SILL catalogue of recommended free software.
