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.

Tresorit
Tresorit is a zero‑knowledge, end‑to‑end encrypted cloud collaboration platform designed for individuals and organizations that need uncompromising data security. It enables users to securely store, sync, and share sensitive files while ensuring that only the data owner and explicitly authorized recipients can access the content. Files are encrypted on the user’s device before upload, and encryption keys are never available to Tresorit, eliminating the risk of provider‑side data access or exposure.
Built as a privacy‑first alternative to conventional cloud services, Tresorit supports secure internal collaboration as well as controlled external data exchange. Teams can share files and folders with granular permission settings, revoke access at any time, and monitor activity to maintain full visibility and control. External sharing is protected through encrypted links and secure email delivery, replacing risky attachments and uncontrolled file transfers.
Tresorit also enables secure, long‑term collaboration with clients and partners through encrypted data rooms that centralize documents, tasks, and approvals in a single protected workspace. Integrated digital signatures allow documents to be reviewed and signed without leaving the encrypted environment, preserving security throughout the entire document lifecycle.
With advanced admin controls, auditability, and configurable data residency options, Tresorit is built to support strict regulatory and compliance requirements. By combining strong security with ease of use, Tresorit allows organizations to collaborate productively while maintaining confidentiality, ownership, and trust over their most sensitive data.
