• End-to-end encryption protects filenames, folder structure, and file content before anything leaves the device. The cryptographic design is open source and documented, with third-party audits published regularly .
• Zero-knowledge architecture means Proton staff cannot decrypt data. Two-factor authentication and device/session logs add another layer of account security .
• Cross-platform coverage is solid: web, iOS, Android, and a native Windows sync client with on-demand file placeholders. Mobile apps support automatic photo backup and biometric unlock .
• Granular link sharing lets me set passwords and expiration dates, keeping the encryption intact while sharing large files or whole folders without size limits .
• Integrated Docs editor (in beta) enables real-time collaboration on Markdown-style documents inside the encrypted vault—handy for quick notes or drafts without leaving the ecosystem .
• Unified Proton ecosystem: one subscription also unlocks Mail, VPN, Calendar, and Pass. Bundled pricing feels efficient when I already rely on multiple Proton services .
• Swiss jurisdiction offers strong data-protection laws, reinforcing the privacy stance beyond the technical measures . Review collected by and hosted on G2.com.
