- Proton VPN’s Stealth protocol is now available in beta for Linux GUI users
- The obfuscation feature hides VPN traffic to better avoid censorship
- It is currently supported on Debian, Ubuntu and Fedora distros
In a big win for open source enthusiasts, Proton VPN has officially launched its proprietary Stealth protocol in beta for Linux. Known to be one of the best VPN services on the market, the Swiss provider continues its push to bring the Linux experience up to par with its Windows and Mac counterparts.
Announced on its official Reddit account, the release introduces powerful obfuscation features to the platform. Simply put, the Stealth protocol makes your VPN connection look like regular, unencrypted internet traffic, allowing you to bypass aggressive internet blocks and firewalls in heavily censored areas.
Speaking directly to TechRadar, the Proton VPN team confirmed the rollout and noted the high demand from the open source community. “Our Linux community has been vocal about their desire to receive Stealth protocol support and we are pleased to now make this a reality,” said a Proton spokesperson.
Being a beta release means that users may encounter instability and bugs. This is why Proton encourages users to report any issues. “We welcome as much user feedback as possible,” Proton told TechRadar.
Proton also confirms that Stealth is only available on the Debian, Ubuntu, and Fedora distros at the moment, with more coming in late summer. If you want to test the feature today, it’s worth noting that it’s currently limited to the Proton VPN Linux GUI (Graphical User Interface) app.
Flying Under the Radar: Why Stealth Matters for Linux
Authoritarian governments, restrictive Internet Service Providers (ISPs), and strict workplace network administrators often use a technique called Deep Packet Inspection (DPI) to detect and block VPN traffic.
Standard VPN protocols, such as OpenVPN and WireGuard, have different cryptographic signatures. Even if your data is securely encrypted, DPI can analyze the metadata of your connection, spot those signatures, and immediately cut off your access to the wider web.
Obfuscated servers, such as those used by Proton’s Stealth protocol, remove this identifying metadata. By wrapping the connection to make it look like standard HTTPS web traffic, Stealth effectively hides the fact that you’re using a VPN in the first place.
As Proton notes, “Linux users now have an efficient, straightforward way to hide their VPN traffic. The Stealth protocol helps avoid Deep Packet Inspection and makes it harder for a VPN to be detected and blocked.”

The stealth beta release is part of a much broader strategy to revamp Proton’s offerings for Linux.
Over the past year, we’ve seen the provider promise a complete Linux makeover that brings parity across its desktop clients. Since then, the company has provided official one-click installs to the Snap store, introduced better stability updates, and most recently expanded its capabilities with a new split-tunneling feature.
Bringing Stealth to Linux fulfills one of the big promises Proton made earlier this year. It also confirms that users running open source operating systems are not left behind when it comes to vital anti-censorship tools.
While CLI (Command Line Interface) users will have to wait a little longer, this GUI beta is a big step forward for digital freedom.
