Zusammenfassung aus Eigentümerschaft und CLOUD-Act-Risiko.
Swiss end-to-end encrypted email by Proton AG (Geneva); 100M+ users, Foundation-controlled since June 2024.
Proton Mail aus der Kategorie Privates E-Mail ist ein EU-eigener Dienst mit Switzerland als Hosting-Standort und ohne erkennbares CLOUD-Act-Risiko.
Proton Mail is operated by Proton AG (Geneva CH), controlled by the non-profit Proton Foundation since June 2024, with end-to-end + zero-access encryption, Swiss jurisdiction (outside EU but under FADP + strong privacy law), own Swiss data centres, ISO 27001, 100M+ users, fully open-source clients, independently audited; Foundation-controlled (non-profit, no VC/PE pressure); the US sub-processors (Zendesk support, Stripe/PayPal/Chargebee billing) are ancillary and never touch the end-to-end-encrypted mailbox data, which sits on Proton's own Swiss data centres, so under a customer-data-at-rest definition CLOUD Act exposure is none, consistent with the rest of the Proton estate.
Wie stark Kundendaten US-Behörden nach dem CLOUD Act (Clarifying Lawful Overseas Use of Data Act) ausgesetzt sind.
Wo die letztliche Kontrolle über das Betreiberunternehmen liegt.
Proton Mail is the original product within the Proton AG ecosystem (Geneva, Switzerland) and the flagship of the privacy-first email category: end-to-end + zero-access encryption (Proton itself cannot read user emails or attachments), 100M+ users, 100,000+ organisations. Since June 2024 Proton AG is controlled by the Proton Foundation, a Swiss non-profit, which structurally rules out future VC / PE acquisition pressure. Pricing: Free (1GB), Mail Plus (€4.99/mo, 15GB + custom domain), Proton Unlimited (€9.99/mo bundle with Mail + Drive + Pass + Calendar + Docs + Sheets + VPN). For the full Proton ecosystem profile see proton-drive and protonvpn. Swiss jurisdiction places ownership_signal: other (Switzerland is non-EU but strong-privacy-law); CLOUD Act exposure none.
