Encrypted Cloud Storage Services

Published: 2025-02-14

The most secure cloud storage services are considered to be those that use end-to-end encryption. This means your files and documents are encrypted before they are uploaded to the cloud, and only you can decrypt them on your device. So, no one else can see or access your data β€” neither the cloud admin, your internet provider, nor any hackers.

Encrypted storage services have clear benefits, and more people prefer them over traditional services like Google Drive, OneDrive, iCloud, and Dropbox.

Let's compare existing cloud storage solutions that support end-to-end encryption:

1. A third-party security audit is expected; the service is currently preparing for it
2. Crypto payments are only available for Lifetime plans
3. The iOS app has a rating of 3.9 in the US
4. The crypto payment link must be requested from support. Crypto payments are only available for Lifetime plans
5. End-to-end encryption is only supported when the Encryption feature is ordered

Which one is the best?

When choosing an encrypted storage, the key criteria for keeping your encrypted data private are open-source сode and security audits. Also, given the strict data protection laws in Europe, it may be reasonable to choose a GDPR-compliant service based in the EU or Switzerland. And finally, if you plan to use the storage on mobile devices, look at its app rating that reflects the usability and user experience.

Based on this, two top services can be highlighted in our list:
πŸ† Filen
πŸ† Proton Drive
The first one has a big advantage – support for the WebDAV protocol, which allows you to connect cloud storage as a network drive. As for the rest, choose what you like and what fits your budget.
