Proton, the Swiss company behind the popular encrypted email service Proton Mail, has officially launched Proton Drive for Business. The new product brings enterprise-grade features to Proton's end-to-end encrypted cloud storage platform, offering businesses a privacy-focused alternative to mainstream services like Google Drive, Dropbox, and OneDrive.
Zero-Access Encryption for Business
What sets Proton Drive apart from competitors is its zero-access encryption architecture. All files are encrypted on the user's device before being uploaded, and Proton never has access to the encryption keys. This means that even if Proton's servers were compromised, attackers would only find encrypted data they cannot read.
For businesses handling sensitive information, this provides an unprecedented level of protection. Law firms, healthcare providers, financial institutions, and any organization dealing with confidential data can store files knowing that no third party—including Proton itself—can access their content.
Proton is based in Switzerland, which has some of the world's strongest privacy laws. Swiss data protection regulations prevent foreign governments from accessing data stored with Swiss companies.
Enterprise Features
Proton Drive for Business includes several features designed for organizational use:
- Admin console: Centralized management of users, storage quotas, and sharing policies
- Team folders: Shared spaces with granular permission controls
- Version history: Recover previous versions of files up to 365 days
- Audit logs: Track file access and sharing for compliance purposes
- SSO integration: Support for SAML-based single sign-on
- Desktop sync: Native apps for Windows, Mac, and Linux with selective sync
Storage and Collaboration
Business plans start with 500GB of storage per user, with options to expand. Teams can create shared folders with role-based access controls, and external sharing is available with password protection and expiration dates.
The service includes real-time collaboration features for documents stored in compatible formats, though the company notes that full office suite integration will be expanded throughout the year.
Pricing Comparison
Proton Drive for Business is competitively priced against other encrypted storage solutions, though it costs more than mainstream options that don't offer end-to-end encryption.
| Service | Price/User/Month | Storage | E2E Encryption |
|---|---|---|---|
| Proton Drive Business | €9.99 | 500GB | Yes |
| Google Workspace | €10.40 | 2TB | No |
| Dropbox Business | €12.00 | 5TB | No |
| Tresorit | €24.00 | 1TB | Yes |
Integration with Proton Ecosystem
Proton Drive for Business integrates seamlessly with other Proton services. Files attached in Proton Mail can be stored directly to Drive, and the Proton Calendar can link to files for event attachments. For organizations already using Proton's suite, the addition of Drive completes a fully encrypted productivity ecosystem.
The company also announced plans to launch Proton Docs, a privacy-focused document editor, later this year, which will provide native document creation and editing within Drive.
How to Get Started
Proton Drive for Business is available immediately. Organizations can sign up for a 14-day free trial with no credit card required. Migration tools are available to help businesses move files from Google Drive, Dropbox, and other services.
