Proton is a privacy-focused suite of encrypted services including Proton Mail, Proton VPN, Proton Drive, Proton Pass, and Proton Calendar, used by privacy-conscious individuals, journalists, activists, and remote workers who want end-to-end encrypted alternatives to Google and Microsoft. Marketed as a private encrypted email and VPN suite, Proton combines zero-access encryption email, a no-logs VPN with NetShield ad blocking, encrypted cloud storage, password manager, encrypted calendar, and a Swiss jurisdiction outside the 14 Eyes. Proton is a strong fit for journalists handling source communications, founders protecting business correspondence, and households consolidating privacy tools under one ecosystem.
