Proton Drive: secure, privacy-first cloud storage

Proton Drive is a privacy-focused cloud storage service from the team behind Proton Mail and Proton VPN. It combines end-to-end encryption, Swiss data protections, and open-source transparency to keep files, filenames and metadata encrypted on-device before upload. The service targets privacy-conscious individuals and organizations that need secure file storage, sharing and encrypted collaboration without ad-based business models.

Platform support and how to get started

Proton Drive runs in any modern browser and offers native apps for Windows, macOS, iOS, iPadOS and Android. Desktop apps provide selective folder sync so you can mirror chosen folders between local drives and the cloud; mobile apps support automatic photo backup and offline access. The Android client is available on Google Play and as an APK for users who prefer sideloading. Over 100 million Proton accounts and more than 100,000 business users rely on Proton services, making Drive part of a large, privacy-centered ecosystem.

Security model and privacy guarantees

End-to-end encryption is implemented client-side: files, filenames and most metadata are encrypted before leaving your device, meaning Proton operates a zero-access model under Swiss jurisdiction. Features that strengthen account security include two-factor authentication and integration with the broader Proton ecosystem. The codebase and encryption components are open source and have undergone independent audits, improving transparency and third-party verification of security claims.

Sync, storage and performance

Desktop synchronization is robust and responsive for day-to-day use; actual transfer speeds depend on local network conditions. Proton Drive uses redundant infrastructure designed for availability and data durability. Selective sync helps conserve local disk space by keeping only chosen folders mirrored, while mobile apps let you choose which files stay offline.

Sharing, collaboration and file management

Secure sharing works via encrypted links or direct sharing with other Proton users. Links can be password-protected, time-limited and revoked at any time. Proton also offers end-to-end encrypted collaboration through Proton Docs and Proton Sheets so teams can edit files in real time while preserving encryption. Standard file operations—uploading, batch uploads, folders, renaming, moving, deleting—are supported, along with version history to recover previous states.

Plans, business features and pricing considerations

There is a free tier to try Proton Drive, plus multiple paid plans that expand storage, sharing limits and business administration features. Business plans add centralized administration, team security controls and the same encryption model applied across users. Some advanced sharing capabilities and very large public transfers may require a paid plan.

Integrations, openness and audits

Proton Drive integrates with other Proton services—most notably Proton Mail for secure large-file sending—so files and encrypted attachments move easily between apps. The service emphasizes openness: many components are open source and subject to independent audits, improving trust for security-conscious users and organizations.

Support, onboarding and documentation

Proton provides a searchable knowledge base, FAQs and setup guides that cover syncing, sharing and privacy features. Paid customers gain access to email support and business-level assistance; community resources help new users get started quickly.

Key strengths and practical limitations

• Strengths: strong client-side end-to-end encryption (including filenames), Swiss jurisdiction and no-ads privacy model, open-source transparency and audits, cross-platform native apps, encrypted collaboration tools, granular sharing controls (passwords, expirations, revoke).
• Limitations: collaboration tools are newer than legacy productivity suites and lack wide third-party integration, some advanced sharing or large-transfer features are gated behind paid tiers, and certain metadata or system integrations that simplify enterprise workflows may be limited by the zero-access encryption model.
