Proton Drive Just Got a CLI and Uploads Up to 4× Faster

Proton Drive has spent years being pitched as the private alternative to Google Drive — secure, Swiss, end-to-end encrypted, but with a quiet asterisk: it wasn't always the fastest or the most flexible. Two recent updates close that gap. Proton Drive now ships a command-line interface for Windows, macOS, and Linux, and a cryptography update that makes uploads up to 4× faster — with none of the encryption traded away.

For a privacy-first storage tool, those are exactly the two objections people used to reach for. Here's what changed and why it matters.

Proton Drive now has a CLI

Proton Drive added a proper command-line interface, built on the Proton Drive SDK and available natively on Windows, macOS, and Linux. At launch it covers the essentials: sign in and out, browse and manage files and folders (trash included), and handle sharing and invitations — all from the terminal, all protected by the same end-to-end encryption as the rest of Proton Drive.

The interesting part isn't the feature checklist, it's what the terminal unlocks: automation. You can script Drive operations the way you'd script anything else —

• upload build artifacts straight after a CI run,
• run scheduled encrypted backups with a simple cron job,
• drop Proton Drive into a deployment pipeline like any other CLI tool,
• manage shares and invitations without opening an app.

The hook is genuinely novel: it's the only end-to-end encrypted cloud storage that works natively in a terminal. If you care about where your data lives and you live in a shell, that combination basically didn't exist before. For developers, sysadmins, and DevOps teams, "privacy-first" no longer means "manual."

Uploads are now up to 4× faster

The second update is pure performance. Proton Drive encrypts file contents with the OpenPGP standard, and Proton adopted a recent cryptographic advance in that standard — moving to a v6 PKESK / v2 SEIPD scheme with AES-GCM for content encryption, which leans on the hardware encryption built into most modern devices.

The result is up to a 4× boost in upload performance. Proton's own example: encrypting a 4 MB file on mobile that used to take 97 ms now takes 32 ms. Crucially, nothing about the security model changed — this is the same end-to-end encryption, just faster.

That matters because "encrypted storage is slow by definition" is one of the most common objections you'll see in comments and comparison threads. It's no longer true. Proton Drive now competes on speed, not only on privacy — which makes it a far more honest "full Google Drive alternative" than it was a year ago.

Bonus for businesses: Easy Switch from Google Workspace

Alongside the Drive news, Proton shipped Easy Switch for Business — an admin-led, self-serve tool that migrates a company's emails, calendars, and contacts from Google Workspace to Proton with no downtime. Google and Proton run side by side during the move, so the team never has to stop working.

The pitch goes beyond privacy preference: Swiss jurisdiction keeps it outside the reach of US laws like FISA and the CLOUD Act, end-to-end encryption means even Proton can't read what's stored, and nonprofit ownership means there's no acquirer waiting to change the terms. For teams fielding hard questions from clients, legal, and regulators about US tech dependency, that's a structural answer rather than a marketing one.

Why this matters if you care about privacy

Privacy tools win converts when they stop asking users to sacrifice anything to use them. With a terminal-native CLI and 4× faster uploads, Proton Drive removes two of the last practical reasons people gave for staying on a less private alternative: it's now scriptable and it's fast. Pair that with Proton's Swiss, end-to-end-encrypted, nonprofit foundation and it's a stronger recommendation than ever — for individuals, developers, and teams alike.

Bottom line

Proton Drive's CLI and its 4× faster uploads are the kind of updates that move a product from "the private option you settle for" to "the private option you'd pick anyway." Encrypted no longer means slow, and privacy-first no longer means manual.
