Proton Drive is the secure workspace for storing sensitive data and collaborating with confidence across teams, clients, and external partners.
With full end-to-end encryption, you can share files, contracts, and business documents securely — and stay in control at all times. Set passwords, expiration dates, or revoke access instantly. Files are encrypted on your device before upload, and only you and your collaborators can access them. Even Proton can’t see your data. Each user gets 1 TB of storage, and you can scale as your organization grows. Proton Drive is developed in Switzerland by the makers of Proton Mail. We’re independent, built on privacy-first principles, and free from Big Tech surveillance, lock-in, or monetization of user data. We offer more than secure storage:
- Real-time collaboration with Proton Docs
- Granular sharing controls for external and internal access
- File recovery for peace of mind
- Cross-device access, including Windows, macOS, iOS, and Android
We also help you meet compliance requirements out of the box. Proton Drive supports:
- GDPR, HIPAA, DORA, NIS2, and ISO 27001
- Independently audited SOC 2 Type II compliance
- No complex setup or third-party integrations required.
By choosing Proton Drive, you show your clients, partners, and regulators that privacy and security are built into your workflows — not an afterthought.
