The end-to-end encrypted productivity stack — now with confidential AI.
Proton is the largest zero-knowledge productivity suite in the world. Mail, VPN, Pass, Drive and Calendar are all end-to-end encrypted by default, and Lumo 2.0 adds Confidential Thinking — a private AI assistant that never trains on your data. This hub tracks every product in the Proton ecosystem, how they combine into a single privacy stack, and how to migrate from Google or Microsoft without losing productivity.
Proton Mail and Calendar keep every message, invite and attachment end-to-end encrypted — even from Proton itself.
Proton VPN and Pass secure the network and every login with a zero-knowledge architecture and independent audits.
Lumo 2.0 brings Confidential Thinking to AI — a private assistant that never trains on your prompts, files or chats.
The confidential AI assistant.
Lumo 2.0 is Proton's private AI assistant. Every conversation is end-to-end encrypted, nothing is used for training, and Confidential Thinking keeps reasoning traces out of Proton's own logs. It's the first mainstream assistant that treats privacy as a product feature, not a policy footnote.
End-to-end encrypted email, made in Switzerland.
Proton Mail is the world's largest encrypted email service. Messages between Proton users are end-to-end encrypted by default, and external mail can be sent password-protected. Custom domains, aliases and unlimited folders make it a real Gmail alternative — not just a novelty.
The open-source, audited privacy VPN.
Proton VPN is the only major VPN built and operated by the same team as an encrypted email provider. Every client is open-source, every audit is published, and Secure Core routes traffic through hardened Swiss, Icelandic and Swedish datacentres before it hits the wider internet.
Encrypted password manager with unlimited hide-my-email aliases.
Proton Pass stores passwords, 2FA codes, notes and credit cards end-to-end encrypted. It bundles SimpleLogin so every signup can get a unique alias — the single biggest upgrade to inbox hygiene most people never make.
Encrypted cloud storage and file sharing.
Proton Drive gives you Google Drive-style storage where Proton has zero ability to read your files. Sharing links are encrypted end-to-end, and desktop sync clients keep local folders and cloud in sync without exposing content.
The recommended migration order so nothing critical breaks mid-way.
For Mail, Calendar, VPN metadata, Pass and Drive contents — yes. Encryption keys live only on your devices and Proton has no ability to decrypt user data.
