Proton Drive - 2026 Pricing, Features, Reviews & Alternatives

Proton Drive is the leading fully-private alternative to Google Workspace and Microsoft 365 — an end-to-end encrypted cloud storage and collaboration ecosystem designed for businesses to build in private.

Trusted by 100,000+ organizations worldwide, Proton Drive gives teams everything they need to store, sync, share, and collaborate, without ever exposing their data to breaches, ransomware, or unauthorized access.

Zero-access encryption — Protect all files, documents, and spreadsheets with end-to-end encryption by default, so only you and authorized users can access them. Not even Proton can access your data.

Proton Docs & Proton Sheets — Collaborate in real-time on documents and spreadsheets with fully encrypted tools built directly into the platform, keeping sensitive content safe from third-party access and AI training.

Secure sharing & full access control — Share files using encrypted links with password protection, expiry dates, and revocable permissions, so you stay in complete control over who sees what and for how long.

No training on your data — Proton Drive's business model is built on subscriptions, not your data. No ads, no data harvesting, and no AI training on your assets.

Native apps for every platform — Access, store, and share any file type securely from anywhere with easy-to-use apps on Windows, macOS, iOS, and Android.

Simplified compliance — Meet the requirements of GDPR, HIPAA, and CCPA with ease. Proton Drive is also ISO 27001 certified and SOC 2 Type II attested.

Open-source & independently audited — Trust in publicly available code and independent security audits, giving your organization verifiable confidence that our apps do exactly what we claim.

Private by design — Headquartered in Switzerland under some of the world's strongest privacy laws, Proton Drive is built with confidentiality as its core, not an add-on.
