Every day people share millions of files, videos and pictures, and the massive use of social networks is replacing other communications channels such as telephone, e-mail or sms. However, these networks are often used without knowing the possible repercussions. Gazela  is a platform with the aim to provide the general society and especially teenagers with the necessary tools to allow them to guarantee their privacy while using social networks. Gazela ’s activity is focused on three main elements: surveillance services, protection services and legal advising services.
