Proton is a suite of privacy-focused applications built around end-to-end encryption, covering email, cloud storage, password management, VPN, video conferencing, document collaboration and an AI assistant. It is aimed at individuals who want private communication and data protection, businesses that need encrypted tools for their teams, and organizations in regulated industries such as healthcare and nonprofits.
Every Proton app uses end-to-end and zero-access encryption, meaning data is protected so that only the account holder can read it, with information kept under Swiss privacy law rather than in conventional cloud infrastructure. The suite includes Proton Mail for encrypted email with spam and tracker filtering, Proton Drive for encrypted file storage and sharing, Proton Pass for password management with breach alerts, Proton VPN, Proton Meet for video calls, Lumo as a privacy-focused AI assistant, and collaborative docs and sheets; all of the apps are open source and independently audited.
Proton offers a permanent free tier covering core features of its services, along with paid plans that add storage, features and priority support; the company states that it carries no ads and earns revenue only from subscriptions.
