We've tested Proton Drive, the Swiss-built end-to-end encrypted cloud storage that puts privacy first. Here's what we found.
Welcome to our Proton Drive review ✨.
Proton Drive is the cloud storage arm of the Proton ecosystem, built by the team that became famous for ProtonMail and that quietly turned end-to-end encryption into a household expectation. The promise is simple but bold: store any file, back up every photo, and share with total confidence, knowing that only you and the people you choose can access your data, not even Proton. We spun up a Proton account, dropped some real files into it, and spent a few days using Drive as a day-to-day Google Drive replacement to see whether the privacy story holds up in practice. 🔒
What immediately sets Proton apart is that they're not retrofitting encryption onto an existing product. The whole stack (Mail, Calendar, VPN, Pass, Drive, and now Docs and Sheets) was built encryption-first, hosted in Switzerland, and protected by some of the strongest privacy laws in the world. For anyone who has watched the slow erosion of trust around mainstream cloud providers (and that's more true than ever with the security threats caused by AI), that's a strong starting point.
Let's dig into what Proton Drive actually feels like to use 🚀!
Signing into Proton Drive feels reassuringly familiar. The sidebar holds the usual suspects (My files, Computers, Photos, Shared, Shared with me, Trash) and the file listing in the middle behaves exactly like every cloud drive you've ever used. There's no learning curve, which is precisely the point. Privacy shouldn't require a degree.
What's different is happening underneath. Every file you drop into Drive is encrypted on your device before it ever touches Proton's servers. The encryption keys are derived from your account password and never leave your control, which means the company hosting your data is also unable to read it. That property is what end-to-end encryption actually means, and it's the one detail that separates Drive from almost every competitor in the space. 💪
The "+ New" menu covers everything you'd expect: upload file, upload folder, create a new folder, plus native Proton documents and spreadsheets. We created a fresh "Uneed Demo" folder in seconds and started populating it.
Here's where things get genuinely interesting. Proton Docs is Proton's answer to Google Docs, and it ships with the same end-to-end encryption guarantee as the rest of the suite. We created a new document inside our demo folder and immediately noticed the small but reassuring badge in the title bar: End-to-end encrypted.
The editor itself is fast, modern, and super clean. You get the usual toolbar (headings, bold/italic/underline, etc) without feeling overbuilt. Documents auto-save in real time (the "Saving…" indicator briefly replaces the encryption badge), and the experience is smooth enough that we forgot we were testing it. We typed up a Q2 marketing roadmap (it's fake!!), complete with objectives and a numbered list of initiatives, and the doc just worked.
For teams that have been holding out on collaborative documents because they don't want their drafts scanned for training data or surfaced in some unrelated ad pipeline, Proton Docs is a serious option. Sheets, the spreadsheet equivalent, is available in the same menu and follows the same encryption model. ✨
Sharing is where most "secure" cloud services quietly fall apart. The moment you generate a public link, your file is one URL leak away from being on the open internet. Proton's approach is much more thoughtful.
Inviting specific people works exactly as you'd expect: type an email, choose "can edit" or "can view", and the invitee gets access tied to their Proton account. Where Drive really shines, though, is the public link controls. Flip the "Create public link" toggle and you get a shareable URL. Then tap the settings icon next to it and the real privacy features appear.
Two toggles, both simple, both crucial:
And if you ever want to revoke access, "Stop sharing" wipes the link and removes everyone with access in one click. This is the kind of UX that turns a security feature into something people actually use. 💡
Open the Photos section and you land on a familiar grid, but every image is encrypted client-side before it leaves your device. Proton Drive's mobile apps (iOS and Android) handle automatic photo backup, with smart categories that should feel immediately recognizable to anyone coming from Apple Photos or Google Photos.
The filter bar covers exactly the kind of granular browsing you'd want from a phone backup: All, Favorites, Screenshots, Videos, Live Photos, Selfies, Portraits, Bursts, Panoramas, RAW. And because the photos are encrypted, Proton genuinely cannot see them, which means there's no facial recognition pipeline, no AI training on your family pictures, no advertiser fingerprinting from the metadata. For anyone uncomfortable with how mainstream photo services have evolved, this is a meaningful alternative. 📸
Drive doesn't exist in isolation. It sits inside the broader Proton account, and the security tooling at that layer is genuinely impressive. The Proton account settings expose features that most cloud providers don't offer at any tier.
A few highlights from the security panel:
This is the kind of layered defense you'd normally expect from an enterprise IT department, not from a consumer cloud product. 💎
Proton Drive isn't just a browser tab. There are native desktop clients for macOS and Windows that sync a chosen folder to your computer, and the "Computers" sidebar entry surfaces every machine connected to your account. The mobile apps (iOS and Android) handle on-the-go uploads and automatic photo backup. Everything stays end-to-end encrypted regardless of which client touches the file, and the keys are derived consistently from your account password.
The desktop sync experience is what finally makes Drive feel like a true drop-in replacement for the cloud services you might be considering leaving. Drag a file into the synced folder, and it's encrypted and uploaded in the background. ⚡
Proton has always priced its products to be reachable, and Drive is no exception. The free tier gets you started with 5 GB at zero cost (enough for a real test rather than a teaser), and the paid plans scale up cleanly.
A quick summary of the individual plans:
There are also business plans for teams that need shared admin controls, custom domains, and centralized billing. Every paid plan ships with the same encryption guarantees as the free tier. Privacy isn't a premium upsell here, it's the default. 💰
A few quick observations from our test, both positive and constructive:
What we loved:
Where there's still room to grow:
None of these are dealbreakers, and Proton has shipped consistently quickly since Drive launched. 🚀
Proton Drive is the cloud storage you choose when you've decided you actually want your files to be yours. The encryption model is real, the UX is genuinely familiar, the sharing controls are the kind of feature most providers should have shipped years ago, and the surrounding ecosystem (Mail, Calendar, VPN, Pass, Docs, Sheets) quietly makes it one of the strongest privacy bundles you can buy.
For founders, journalists, designers, indie hackers, and anyone with sensitive client work, this is an easy recommendation. For everyone else, it's a chance to opt out of the surveillance economy without giving up anything you actually use day-to-day.
And that wraps up our Proton Drive review. If you've been looking for an end-to-end encrypted cloud storage that doesn't ask you to choose between privacy and usability, this is the one to try. ✨
