Proton is a privacy-focused digital platform offering encrypted email, cloud storage, calendar tools, and password management services designed to protect online communication and sensitive data. Known initially for its secure email solution, Proton has evolved into a broader ecosystem that provides multiple privacy-first tools within a single integrated environment. The platform aims to give users greater control over their digital presence by reducing reliance on data-driven advertising models and prioritising encryption.
