Strong encryption

End-to-end encryption ensures your Proton Drive cloud storage is protected from third parties. Where Google and Microsoft retain the encryption keys, Proton ensures only you have access to your private key. Proton Drive uses OpenPGP to encrypt every file on your device before it reaches the cloud. In addition, Proton uses elliptic curve cryptography to secure your files from all known attacks, and employs cryptographic signatures to verify the authenticity of your files so you can immediately detect any tampering.

European privacy laws

Headquartered in Switzerland, Proton protects your data with some of the strictest privacy laws in the world. By storing business data with Proton, you protect it from the CLOUD Act, a United States federal law which allows authorities to compel US-based tech companies to produce stored data for investigations, even when the data is located on servers abroad. You also keep it safe from EU and UK jurisdiction, as well as surveillance and censorship.

Certification and compliance Split Right

Compliance is non-negotiable, especially in industries such as healthcare, legal, and finance. Proton is SOC 2 Type II and ISO 27001 certified; the international gold standard for information security management. Proton Drive is engineered to help your organization meet data‑protection mandates, including GDPR, CCPA, and HIPAA. By storing your files on a certified, compliant platform, you can accelerate your own certification.

Backups and versioning

Even with the best ransomware defenses, data breaches can still occur. Proton Drive’s automatic syncing creates a new version of every file each time it changes, and its version‑history feature lets you roll back to a clean copy instantly. If you’re ever subject to a ransomware attack, simply wipe the compromised device, restore the previous versions from Proton Drive, and get back to work.

Open-source and audited

All Proton apps are open source and audited by independent security experts to ensure they’re safe from known vulnerabilities. Explore our code and review our audits.

Anti-censorship

Bypass censorship with alternative routing that automatically detects when your internet connection is being censored and re-routes your traffic accordingly to access your Proton account. You can also access Proton Drive using the Tor anonymity network, whether to avoid advanced censorship or just for extra privacy.

Who can access your data?

When you use Proton Drive, you stay in complete control of your data. Proton’s end‑to‑end encryption guarantees that only you and people you choose to share with can access your files. Because the encryption keys never leave your device, Proton cannot access, use, or share your data. Your data belongs to you alone.
