- Tuta announced a closed beta for quantum secure cloud storage
- Google and Microsoft have yet to commit to quantum-resistant timelines
- Conventional encryption can be broken by quantum computers on a large scale
While Google and Microsoft have yet to announce quantum-resistant encryption for their cloud storage services, a German email provider is launching just that.
Tuta, known for its encrypted email platform, has announced a closed beta for Tuta Drive, a cloud storage solution built with quantum-safe cryptography.
Starting April 16, select 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 matters to your files
Conventional encryption used by Google Drive and OneDrive may eventually be broken by large-scale quantum computers.
Although these machines don’t exist yet, files stored today can be harvested and decrypted years later as the technology matures.
Tuta’s approach uses zero-knowledge architecture, meaning the company cannot decrypt user files itself 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 invite-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,” says 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 insecure email offered by mainstream providers…We are proud to announce that we are ready to add a Drive solution to Tuta that uses the same cryptography.”
Mainstream providers have not publicly committed to quantum-resistant cloud storage timelines, which puts Tuta ahead of much larger competitors in preparing for a post-quantum future, even if that future is still years away.
Unfortunately, most curious users can’t access the service yet, and quantum-resistant encryption solves a problem that doesn’t currently exist.
For privacy-focused individuals and organizations, however, Tuta Drive offers a rare combination of zero-knowledge architecture and future-proof cryptography that mainstream providers have yet to match.
That said, it’s interesting that a small German company beat American tech giants to something that will ultimately matter to everyone.
