Proton AG, the Geneva-based company behind Proton Mail, Proton VPN, Proton Drive, and Proton Pass, has announced that it has surpassed 100 million registered users worldwide. The milestone represents a doubling of its user base in just 18 months, driven by growing global awareness of digital privacy and increasing distrust of US tech companies.
Founded in 2014 by CERN scientists, Proton started as an encrypted email service and has since expanded into a comprehensive privacy ecosystem that aims to be a complete alternative to Google's suite of services.
Proton's Product Ecosystem
What began as a single encrypted email service has grown into a full-featured privacy platform:
| Proton Service | Replaces | Key Feature |
|---|---|---|
| Proton Mail | Gmail, Outlook | End-to-end encrypted email |
| Proton VPN | NordVPN, ExpressVPN | Swiss-based no-logs VPN |
| Proton Drive | Google Drive, Dropbox | Zero-access encrypted storage |
| Proton Calendar | Google Calendar | Encrypted calendar |
| Proton Pass | 1Password, LastPass | Open-source password manager |
What's Driving the Growth
Several factors have contributed to Proton's rapid user growth in 2025-2026:
- Geopolitical tensions: Increasing concerns about US government data access policies have pushed European users and businesses toward Swiss-hosted alternatives
- Enterprise adoption: The launch of Proton for Business has attracted thousands of companies looking for GDPR-compliant alternatives to Google Workspace and Microsoft 365
- Proton Drive maturity: With the recent launch of Proton Drive for Business, the company now offers a credible alternative to the full Google/Microsoft stack
- Privacy regulation: The EU AI Act and ongoing GDPR enforcement are making businesses more privacy-conscious
As a Swiss company, Proton is protected by some of the world's strongest privacy laws. Switzerland is not part of the EU or the Five Eyes intelligence alliance, and Swiss law prohibits the kind of mass surveillance that is common in the US and UK.
The Competitive Landscape
Proton's growth comes at a time when the market for privacy-focused European tech is expanding rapidly. The company faces competition from other European providers, each carving out their own niche:
- Tuta (Germany): Proton's closest competitor in encrypted email, with a strong focus on quantum-resistant encryption
- Tresorit (Switzerland): Competing in encrypted cloud storage with strong enterprise features
- Mullvad VPN (Sweden): A privacy-maximalist VPN with anonymous account creation
- Nextcloud (Germany): Open-source collaboration with self-hosting options
What 100 Million Users Means for the Privacy Movement
The 100 million user milestone is significant beyond Proton itself. It demonstrates that privacy-focused services can achieve mainstream scale — something that was widely doubted just a few years ago.
"When we started Proton in 2014, the conventional wisdom was that people don't care about privacy. 100 million users later, we can say definitively: people do care, and they're willing to switch to services that respect their rights." — Andy Yen, CEO of Proton
For the broader European tech ecosystem, Proton's success serves as proof that European companies can compete with Silicon Valley giants — not by copying them, but by offering something fundamentally different: technology that puts users, not advertisers, first.
