- Proton VPN’s Stealth protocol has graduated to a stable release on Linux
- Users no longer need to switch to beta channels to use it
- This upgrade follows a string of major Linux-focused improvements
If you use one of the best VPN services on a Linux machine, bypassing restrictive firewalls and internet blockades just got significantly easier. After spending months in a rigorous testing phase, Proton VPN has officially moved its custom anti-censorship Stealth protocol into the stable Linux release.
Announced directly by the Proton Team on Reddit, the highly anticipated update means Linux users no longer have to opt into experimental testing channels just to disguise their VPN traffic. Instead, the feature is now rolling out to the main branch for everyday users to access out of the box.
This move marks a major milestone following the initial news of Proton VPN’s anti-censorship Stealth protocol finally landing on Linux in beta. Originally launched to help users in highly restrictive regions like Russia and Iran, Stealth works by obfuscating your connection. It wraps your VPN traffic in an extra layer of TLS encryption, making it look like completely standard, secure web browsing (HTTPS).
By hiding in plain sight, Stealth makes it incredibly difficult for network administrators, internet service providers (ISPs), and government censors to detect and block your VPN usage using deep packet inspection (DPI).
What you need to know about Stealth on Linux
Early feedback from the community has been largely positive, though a few users on specific distros, like Debian Sid, noted they temporarily had to revert to WireGuard to maintain a stable connection.
If you hit an issue, the developers request that you submit a bug report including your distro and version, app version, what you were doing, and what exactly went wrong.
While the obfuscation feature has officially graduated to the main stable release, the Proton Team was quick to note that users will still see a "beta" label next to the protocol inside the application itself.
"The beta label stays until we're confident it holds up across every distro, network condition, and edge case you throw at it, so keep the reports coming," the company explained to its Reddit community.
To try the feature, users simply need to update the Proton VPN Linux app to the latest version and navigate to the application settings to switch protocols. Because the update is actively rolling out across various mirrors, a handful of users on the Reddit thread reported a slight delay in receiving the newest patch (v4.17.2).

Proton VPN Linux's updates recap
This stable release is just the latest in a rapid-fire series of updates for the open-source operating system. Earlier this year, Proton VPN revealed a major Linux makeover for both GUI and CLI users, bringing the Linux client much closer to feature parity with its Windows and Mac counterparts.
The Swiss-based privacy company has also been busy making the app more accessible. Recently, Proton VPN on Linux got a huge accessibility boost with 20 new languages. For those who prefer streamlined software management, Proton VPN brought official one-click installs to the Linux Snap Store as well.
With Stealth now readily available in the main client, Linux users can finally enjoy the full everyday benefits of Proton VPN, quietly unveiling massive under-the-hood protocol upgrades.
Whether you're trying to bypass a strict university firewall or secure your communications in a country with heavy internet censorship, Stealth ensures your private connection remains protected.
