What is Proton VPN?
Proton VPN is a well-established VPN service originally developed by CERN scientists, known for its strict no-logs policy and open-source client. The Linux version available on Flathub is built from Proton's official open-source code but is a community-maintained build, not an official Proton AG release. It supports modern protocols like WireGuard and OpenVPN, ensuring strong encryption and performance across various Linux distributions.
This tool is ideal for privacy-conscious users, developers, and anyone needing to bypass geo-restrictions or secure their connection on public Wi-Fi. It serves as a direct functional replacement for Windows-based VPN clients, offering a familiar interface for managing connections, server selection, and security settings without the overhead of proprietary Windows software.
Unlike network monitoring tools like GlassWire, Proton VPN focuses on outbound traffic security rather than inbound analysis. While GlassWire alerts you to suspicious connections, Proton VPN actively hides your IP and encrypts your data. The experience is straightforward: you connect, and your traffic is routed through secure servers, providing a clean, uncluttered interface that prioritizes privacy over detailed network diagnostics.
Best for: Users who need a secure, privacy-focused VPN to hide their IP and encrypt traffic on Linux.

How to install Proton VPN on Linux

If you are coming from Windows VPN clients, the workflow is similar: select a server and connect.
