4 women are murdered every day in Brazil. Traditional protection systems proved insufficient and disconnected. Her Dome transformed the electronic ankle monitor, previously used only to track aggressors, into a real-time prevention network. By connecting GPS data, judicial records, police information and social services, it created an automated layer of protection. If an aggressor approaches the victim, the system detects proximity threats and triggers alerts before harm occurs: the police are immediately notified, without the woman needing to ask for help herself. Through the SP Mulher Segura app, the mobile became more than a communication device. It became the interface between the State and the woman, providing protection, autonomy, and dignity. Women hold in their hands an invisible, accessible and reliable shield.
