Best secure cloud storage (2026)
作者：Matteo Vigliante · 更新于 2026年5月29日
For privacy, the defaults matter more than the feature list. Proton Drive encrypts end-to-end out of the box, is based in Switzerland, and comes from a company with a decade-long privacy record in Proton Mail.
我们的选择
Proton Drive applies zero-knowledge encryption to everything by default, so the provider cannot read your files. It operates under Swiss privacy law and is built by the team behind Proton Mail, which gives it a verifiable track record rather than a marketing claim.
It is not the cheapest per gigabyte, and the ecosystem is younger than the mainstream players, so the desktop and mobile apps are still maturing. If privacy is the priority and not an afterthought, the trade-off is worth it.

常见问题
What is the most secure cloud storage?
Proton Drive, for its end-to-end encryption by default, Swiss jurisdiction, and the track record of the Proton team behind it.
What does zero-knowledge encryption mean?
It means the provider cannot read your files because the encryption keys never leave your device. Even the company hosting the data cannot decrypt it.
Is Proton Drive free?
Proton Drive offers a free tier with limited storage. Paid plans add more space and are still end-to-end encrypted by default.
