Encrypted Cloud Storage: Keep Your Files Private

Encrypted Cloud Storage

Standard cloud storage providers like Google Drive and Dropbox can access your files. Their employees, automated systems, and government requests can all expose your private documents. Encrypted cloud storage ensures that only you can read your files, not even the storage provider.

The Problem with Standard Cloud Storage

• Server-side access: Providers hold the encryption keys and can decrypt your files
• Government compliance: Providers must hand over files when served with legal orders
• Employee access: Technical staff may have the ability to view your files
• Data mining: Some providers scan file contents for advertising or AI training purposes
• Breach exposure: If the provider is hacked, your unencrypted files are exposed

Zero-Knowledge Encrypted Storage

Zero-knowledge encryption means the provider cannot read your data:

• Tresorit: Swiss-based, zero-knowledge encryption, GDPR compliant
• Proton Drive: From the makers of ProtonMail, end-to-end encrypted
• Sync.com: Canadian-based, zero-knowledge encryption, good free tier
• MEGA: End-to-end encryption with generous free storage (privacy practices have been debated)
• Filen: German-based, zero-knowledge encryption, open-source clients

Encrypt Your Own Files

You can also encrypt files before uploading to any cloud service:

• Cryptomator: Creates encrypted vaults that sync with any cloud provider. Open-source and free
• VeraCrypt: Creates encrypted containers that can be stored anywhere
• 7-Zip: Password-protect and encrypt individual files or archives
• This approach works with any cloud storage, even Google Drive or Dropbox

Choosing Encrypted Storage

• Verify the provider uses zero-knowledge encryption (client-side encryption)
• Check the provider's jurisdiction and privacy laws
• Review whether the code is open-source and independently audited
• Consider the provider's business model: paid services are less likely to monetize your data
• Ensure the service works across all your devices

Your files deserve the same privacy as your conversations. Zero-knowledge encrypted cloud storage ensures that your documents, photos, and backups remain private even if the storage provider is breached or served with a legal order.
