ALCASAR is a free and open source project for managing Internet access for public, corporate or home networks. It authenticates and protects users' access regardless of their equipment (PC, tablet, smartphone, game console, TV sets, etc.). It includes several filtering mechanisms per user adapted to private needs (parental control and filtering of connected objects) or to internal charters and regulations (companies, associations, leisure and accommodation centers, schools, libraries, town halls, etc.). In France, it allows network managers to comply with the law (CPCE). ALCASAR is compatible with the European device "WIFI4EU" which facilitates the deployment of Internet for local authorities.


It includes several filtering systems complying private needs (parental control, filtering of connected objects) or public needs (schools, vacation centers, companies, libraries, etc.). In France, ALCASAR allows people in charge of consultation network to meet the law.


Beyond these aspects, ALCASAR is used as a teaching aid for networks security training courses ('security of networks', 'control with legal and ethical aspects').


ALCASAR is an independent and free project (GPLv3). The developer team is managed by Richard Rey (rexy) and Franck Bouijoux (3abtux). This "ALCASAR team" consists of "senior" developers, "junior" developers, "Padawans", technic hotliners, writers and testers identifiable on the forum.
