Proton VPN as a Linux alternative to CyberGhost VPN
Updated
Our verdict
Proton VPN is a strong, open-source replacement for CyberGhost on Linux, particularly if you value transparency and don't mind a Flathub build. It covers the core needs: WireGuard/OpenVPN, kill switch, and DNS protection. The main gap is the lack of native split tunneling for specific apps, which forces you to rely on system-level routing or manual configuration. For users who need strict app-level exclusion or prefer a polished, official desktop experience, it may feel less convenient than CyberGhost's Windows client, but for most privacy-focused users, the trade-off is worth it.

Opening your CyberGhost VPN files
There is no direct file compatibility between CyberGhost and Proton VPN. You cannot import CyberGhost profiles, configurations, or saved server lists into Proton VPN. Both services use their own proprietary account systems and server directories, so you must create a new Proton account and configure settings from scratch. Any local CyberGhost configuration files are irrelevant to Proton VPN's operation.
Switching from CyberGhost VPN to Proton VPN, step by step
- Create a Proton VPN account if you do not already have one
- Install Proton VPN from Flathub or your distribution's package manager
- Log in to the Proton VPN client with your credentials
- Configure the kill switch in the app settings to ensure traffic blocks on disconnect
- Set up automatic connection if supported by your desktop environment or use a startup script
- Test the connection and verify DNS leak protection using online tools

How to install Proton VPN on Linux
flatpak install flathub com.protonvpn.wwwFrequently asked questions
Is the Proton VPN Linux app official?
No, the Flathub version is built from Proton's open-source code but is not officially supported by Proton AG. It is a community-maintained build, so updates and support may differ from the official Android or web clients.
Can I use Proton VPN for gaming on Linux?
Yes, Proton VPN supports low-latency protocols like WireGuard. However, you should test your specific game and server region, as VPN overhead can affect online gaming performance. There is no native split tunneling, so you must ensure the game traffic is routed through the VPN if desired.
How do I exclude specific apps from the VPN?
Proton VPN does not offer native per-app split tunneling on Linux. You must use system-level tools like iptables or nftables to route specific IP addresses or ports outside the VPN, or run the app in a separate network namespace. This requires technical knowledge and manual setup.
