OpenVPN: A Time-Tested Standard

Introduction

In a world where the speed and simplicity of WireGuard have become the new standard, OpenVPN remains one of the most reliable and flexible VPN protocols. It works both on traditional computers and on networking equipment, providing cross-platform compatibility and a high level of security. However, to understand how to use it, it is important to distinguish between the protocol itself and its client applications.

OpenVPN: The Engine

OpenVPN is, first and foremost, an open-source project and protocol. It is the “engine” of the VPN tunnel. The protocol uses SSL/TLS for encrypting data and creating a secure channel between client and server. Its main advantage is incredible flexibility. You can configure almost any aspect of its operation:

• Choice between TCP and UDP.
• Use of different encryption algorithms.
• Fine-tuned configuration of routing and network rules.

Working with the protocol involves the command line, which makes it a powerful tool for system administrators and engineers.

OpenVPN Connect: The Control Panel

OpenVPN Connect is the official client application developed by OpenVPN Inc. It is not a separate protocol but a convenient and intuitive interface for connecting to OpenVPN networks. Its key purpose is to simplify the process for the end user.

Main features of OpenVPN Connect:

• Simple import: You only need to import a configuration file (.ovpn), and the application will automatically set all parameters.
• Centralized management: For corporate users, the application allows easy management of connections to different networks.
• Ease of use: For most users who do not need fine-tuned settings, OpenVPN Connect is the ideal choice.

Analogy: The Engine and the Dashboard

Imagine that OpenVPN is the engine, which engineers can configure and adapt for any task. It is powerful and reliable but requires deep knowledge.

OpenVPN Connect is the dashboard and user-friendly interface in a car. It allows you to start the engine, drive, and see the necessary indicators without diving into how the engine works.

Conclusion

The choice between using pure OpenVPN and OpenVPN Connect depends on your task.

• Use pure OpenVPN if you are a system administrator who needs maximum flexibility and is ready to work with the command line.
• Use OpenVPN Connect if you are an end user who needs a simple and reliable solution to connect to a VPN network without unnecessary complications.
