Proton

EFTA verified

Swiss privacy suite with end-to-end encrypted email, calendar, drive, password manager and VPN.

Website from 3,99 € / Monat

Confidence: high

Proton offers an entire ecosystem around encrypted communication: Mail, Calendar, Drive, Pass (passwords) and VPN. Its headquarters in Switzerland, end-to-end encryption and own server hardware in Switzerland and Germany make Proton one of the best-known privacy alternatives to Google and Microsoft. All apps are open source; Proton is ISO/IEC 27001 certified and has a SOC 2 Type II report. Proton Mail Plus starts at €4.99 per month (€3.99 with annual billing), the Proton Unlimited bundle at €12.99 per month.

Note on ownership: Headquartered in Switzerland (EFTA, not EU, but strict data protection law), owned by the non-profit Proton Foundation. Proton owns and operates its own server hardware in Switzerland and Germany – so it is not dependent on a hyperscaler.
