ALCASAR is a free Internet Access Controller for private or public consultation networks. It authenticates and protects users' access regardless their connected equipment (PC, smartphone, game console, TV sets, etc.).


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').
