What is OpenVPN?
OpenVPN has been around since the early 2000s and is one of the most established VPN solutions available. It operates as both a client and a server, allowing you to connect to existing VPN providers or host your own private tunnel. The software is highly stable, with a long history of security patches and protocol updates that make it a standard in the industry for remote access and privacy.
This tool is ideal for users who want full control over their network traffic without relying on proprietary client software. It appeals to technically inclined individuals, sysadmins, and anyone who prefers a transparent, auditable solution over black-box commercial apps. If you are comfortable reading configuration files or using a command-line interface, OpenVPN offers a level of customization and reliability that few other tools match.
Compared to CyberGhost, OpenVPN feels more raw and less user-friendly out of the box. CyberGhost provides a polished, one-click graphical interface designed for general consumers, whereas OpenVPN often requires manual setup of configuration files (.ovpn) or a third-party GUI wrapper. However, OpenVPN is generally lighter on system resources and does not collect usage data, offering a cleaner, more private experience for those willing to do the initial configuration work.
Best for: Users who prioritize privacy, control, and stability over a polished, one-click user interface.

How to install OpenVPN on Linux
sudo apt install openvpnsudo apt install openvpnsudo dnf install openvpnsudo pacman -S openvpnsudo zypper install openvpnTips for Windows users
If you are moving from CyberGhost, you will need to obtain .ovpn configuration files from your VPN provider. CyberGhost handles authentication and server selection automatically, while OpenVPN requires you to specify the server address, credentials, and certificate files manually. You may need to install a GUI frontend like OpenVPN GUI or use a network manager applet to manage profiles more easily. Note that CyberGhost-specific features like kill switches or leak protection must be configured via system settings or iptables rules on Linux.
OpenVPN: frequently asked questions
Does OpenVPN have a graphical interface on Linux?
The core package is command-line only. You need to install a separate frontend like OpenVPN GUI, NetworkManager-openvpn, or a desktop app like WireGuard (if supported) for a visual experience.
Can I use OpenVPN with my existing CyberGhost subscription?
Yes, if CyberGhost provides OpenVPN configuration files. Most major providers offer these, but you must download the specific .ovpn file for the server you wish to connect to.
Is OpenVPN faster than CyberGhost's proprietary protocol?
Performance depends on the server and network conditions. OpenVPN is efficient, but proprietary protocols may have optimized routing. Generally, OpenVPN is very fast and reliable for typical internet use.
How do I start OpenVPN automatically on boot?
You can create a systemd service unit for OpenVPN or use your desktop environment's network manager to set the connection to connect automatically at startup.
