Bewertungsnotizen

Proton AG (Geneva, Route de la Galaise 32, Plan-les-Ouates; founded 2014 by Andy Yen and a team from CERN) is controlled by the non-profit Proton Foundation (since June 2024) with no venture-capital investors anywhere on the cap table, runs 11,496 owned-and-operated servers across 117 countries with Swiss-jurisdiction primary processing, ISO/IEC 27001:2022 + SOC 2 Type II certifications covering all Proton product lines, and zero-knowledge end-to-end encryption that makes the customer the sole keyholder; Swiss-headquartered and non-profit-foundation-controlled, with a public DPA, disclosed sub-processors, and US sub-processors (Zendesk for support, Stripe / PayPal / Chargebee for billing) that are ancillary and never touch the end-to-end-encrypted file data on Proton's own infrastructure; however, every Proton IP range reaches the internet only through Cloudflare's network (AS13335 as the sole upstream, the pattern of Magic Transit DDoS scrubbing, verified via RIPEstat on 2026-10-03), which carries TLS-encrypted traffic and connection metadata but does not terminate TLS and is not named in Proton's processor lists, so CLOUD Act exposure is recorded as minor (a transient US network layer with no plaintext access and no data at rest).

Über Proton Drive

Proton Drive is the encrypted cloud-storage product within the Proton AG ecosystem (Mail, Drive, VPN, Pass, Calendar, Docs, Sheets, SimpleLogin), headquartered at Route de la Galaise 32, 1228 Plan-les-Ouates, Geneva, Switzerland. Founded in 2014 by Andy Yen and a team that originally met at CERN, Proton serves more than 100 million users worldwide and runs the most singular ownership structure in the directory: as of June 2024 the non-profit Proton Foundation (Swiss, Geneva; trustees include Andy Yen, Antonio Gambardella, Carissa Véliz, Tim Berners-Lee, and Dingchao Lu) is the controlling shareholder of Proton AG. The company explicitly takes no venture capital, its non-profit structure is designed to permanently prevent takeover attempts, and there is no path for a US-PE / US-VC investor to influence governance.

Compliance posture is exceptional. Proton holds ISO/IEC 27001:2022 with the ISMS scope covering all product lines (Mail, Drive, Pass, VPN, Calendar, SimpleLogin) and SOC 2 Type II. The infrastructure footprint is also unusual: by February 2025 Proton had 11,496 servers across 117 countries, all owned and operated by Proton itself, not rented from hyperscalers. Primary processing is in Switzerland; named US sub-processors are limited to ancillary functions (Zendesk for customer support, Chargebee for billing automation, Stripe and PayPal for card payments, Atlassian for support-data storage) and do not touch zero-knowledge-encrypted customer files. Standard Contractual Clauses, Binding Corporate Rules, and certifications govern any third-country transfers. Switzerland is not in the EU but holds an EU adequacy decision under Art. 45 GDPR, so transfers EU↔CH require no SCCs.

Drive pricing in EUR: Free includes 5 GB encrypted storage plus Docs and Sheets; Drive Plus is from approximately €4/month for 200 GB and file-version recovery; Proton Unlimited at ~€10/month adds 500 GB, Mail with 15 custom addresses, VPN, Pass, and Proton Sentinel advanced account protection; Duo (2 TB, 2 users), Family (3 TB, 6 users), and Drive Professional (1 TB/user for business). Best fit: every EU and Swiss procurement-grade buyer requiring zero-knowledge encrypted file sharing with the strongest sovereignty story in the directory; particularly compelling for journalists, NGOs, regulated industries, and any organisation needing genuine "no one outside the customer can access this data" guarantees.
