Comparison
Encrypted storage keeps files. A vault keeps secrets.
Account-based encrypted drives such as Tresorit and NordLocker do honest end-to-end encryption at scale. What they cannot do is remove the account, or make your data deniable. Those are different properties, for a different kind of file.
Is encrypted cloud storage enough for my most private files?
For most files, yes. A reputable zero-knowledge drive protects content well. But the account still ties your identity to the data, and its existence, size and activity are known. Nothing about it is deniable. For the files that should not appear on any stored list at all, an encrypted vault like Sealby is the better fit: no account, no company copy, no stored vault list or count.
Where Encrypted cloud drives shines
- Genuine end-to-end encryption from reputable providers
- Real capacity: terabytes, sharing links, team features, every platform
- The right tool for encrypting your general files and backups
Where it falls short
- An account attaches your identity to the existence of your data
- Metadata survives encryption: that you store, roughly how much, and when it changes
- Nothing is deniable. The account and its contents can be listed on demand
- A drive behaves like a workspace, not a sealed vault. Files open, preview and cache like ordinary documents
The honest verdict
Use both, for different levels. An encrypted drive is where your files live. A vault is where your secrets live. The drive gives you scale and reach with strong encryption. Sealby gives the few files that really matter something no drive offers: no account, no company copy, and no stored list or count of your vaults.
Common questions
What can a zero-knowledge cloud provider still see?
Not your content. That is the point of the encryption. But typically: who you are, that you store data, roughly how much, and when you access it. That information, attached to your identity, is exactly what a vault with no account and no provider never creates.
What about open-source tools like Cryptomator?
A respected approach. It encrypts files on your device inside your existing cloud drive, with no extra account. It shares Sealby’s no-provider spirit for general files. But it is a file-encryption layer, not a phone vault: no deniable vaults, no duress option, and a workflow built around drives rather than a sealed app.
