- Tuta announced a closed beta for quantum-safe cloud storage
- Google and Microsoft have not yet committed to quantum-resistant deadlines
- Conventional encryption could be broken with large-scale quantum computers
While Google and Microsoft have yet to announce quantum-resistant encryption for their cloud storage services, a German email provider is launching exactly that.
Tuta, known for its encrypted email platform, has announced a closed beta version of Tuta Drive, a cloud storage solution built with quantum-safe cryptography.
Starting April 16, selected users will get early access to test the service, which encrypts all files end-to-end using a hybrid protocol of traditional and quantum-resistant algorithms.

Why quantum resistance is important for your files
The conventional encryption used by Google Drive and OneDrive could eventually be cracked by large-scale quantum computers.
While those machines don’t exist yet, files stored today could be collected and decrypted years later when the technology matures.
Tuta’s approach uses a zero-knowledge architecture, meaning the company itself cannot decrypt users’ files or share them with third parties.
All data is hosted in Germany under strict data protection laws, adding another layer of privacy protection.
The beta is invitation-only, creating an exclusive early access program for testers to explore core functionality and provide feedback.
The service integrates seamlessly with Tuta’s existing email and calendar ecosystem, which already serves more than ten million users, including journalists, whistleblowers and activists.
“With Tuta Drive, we are taking the next step towards offering a complete private digital workspace,” said Arne Möhle, CEO of Tuta.
“Today, more than ten million citizens and businesses, including journalists, whistleblowers and activists, use Tuta Mail as an alternative to the insecure email offered by major providers… We are proud to announce that we are ready to add a Drive solution to Tuta that uses the same cryptography.”
Major vendors have not publicly committed to quantum-resistant cloud storage timelines, putting Tuta ahead of much larger competitors in preparing for a post-quantum future, even if that future is still years away.
Unfortunately, the most curious users still cannot access the service and quantum-resistant encryption solves a problem that does not currently exist.
However, for privacy-focused individuals and organizations, Tuta Drive offers a rare combination of zero-knowledge architecture and future-proof cryptography that is not yet matched by major vendors.
That said, it’s interesting that a small German company beat American tech giants on something that will eventually matter to everyone.
