Get started with 5 GB free cloud storage
Proton Drive's strong encryption goes beyond other secure cloud solutions. End-to-end encryption ensures that no one, not even us, can access your files. Files, file names, and folder names and more, are all fully encrypted at rest and in transit to your secure cloud.
Proton is based in Switzerland, which means your files are protected by some of the strictest privacy laws in the world. Proton Drive is a neutral and stable digital vault for your files.
We believe in trust through transparency. Proton Drive is open source, so anyone can verify that our encrypted cloud storage works as described. Proton Drive is also routinely audited for privacy and security by independent third-party experts.
Choosing Proton Drive is a choice for a better internet. Proton Drive is part of a wider ecosystem of privacy-first products. By using Drive and our other products, you are helping to create an internet where people, not Big Tech, hold the power.
Optional features like password protected files and expiring file sharing links enhance security even further. Best of all, there are no file size limits.
