Living in a time of online privacy and security, reliable data protection is essential. Virtual Private Networks (VPNs) using the OpenVPN protocol provide encryption and anonymity, significantly reducing the risk of cybersecurity exposure. But what is OpenVPN and how does it work?
Widely recognized as one of the leading VPN protocols, OpenVPN stands out for its strong encryption and adaptability. It is a key component of ZoogVPN’s supreme security offering, providing users with reliability and flexibility. This article aims to provide users with the necessary knowledge to ensure that they can effectively implement OpenVPN into their security solutions.
What is OpenVPN Protocol
OpenVPN is a secure VPN protocol that establishes secure online connections using a special SSL/TLS-based security protocol. Since 2001 this collaborative approach has been licensed under the General Public License (GPL), which allows for widespread distribution. Based on the Secure Socket Layer (SSL) encryption protocol, the OpenVPN tunneling protocol ensures the privacy of data transmitted over the Internet using AES-256 encryption. Its open-source code allows simple ongoing auditing, enabling users to identify and fix any issues. Known for its robust security, OpenVPN not only guarantees increased privacy but also provides a fast connection that can overcome most firewall barriers.
How OpenVPN Protocol Works
The OpenVPN protocol includes encryption rules, secure connection procedures, and various transport modes, some of which were pre-existing and others specifically designed for OpenVPN. Understanding OpenVPN begins with recognizing it as a VPN protocol that defines a set of rules for creating VPN tunnels, encryption methods, and data packet processing.
OpenVPN works by establishing a secure connection, or tunnel, between a user’s device and a VPN server. This connection encrypts all data traffic passing through it, ensuring privacy and security. It all starts when the client initiates a connection request to the VPN server, which verifies the authenticity of the client’s credentials. After authentication, a secure channel is established using SSL/TLS encryption. This encrypted tunnel encapsulates the user’s data packets, preventing them from being intercepted or monitored by third parties. The encrypted data is then transmitted over the Internet to a VPN server, where it is decrypted and forwarded to its destination. In contrast, data from the destination is encrypted by the server, transmitted back through a protected tunnel, and decrypted by the client. This process ensures that all data exchanged between the client and server remains private and secure.
How secure and fast is OpenVPN?
OpenVPN is considered to be one of the most secure VPN protocols, offering strong encryption and privacy features. The OpenVPN enhances security by using a private security protocol based on TLS and SSL standards that offers widely accepted encryption. It ensures data security with 256-bit encryption and Perfect Forward Secrecy technology, which regularly updates encryption keys for added protection. Authentication checks are done in Transmission Control Protocol (TCP) mode, and options such as Hash-based Message Authentication Code (HMAC) are available. The open-source nature of OpenVPN ensures that it is constantly monitored by privacy experts around the world, which ensures that issues are addressed quickly.
While OpenVPN is probably not always the fastest option, it remains popular due to its robust security measures despite potential speed issues. With more than 70,000 lines of code and complex server-side performance issues, it can run into performance problems during infrastructure renovations. Although speeds can vary depending on factors such as server load and network traffic, OpenVPN’s strong security features make it a better choice for users who prioritize data privacy and security, even if it doesn’t always offer the fastest connection speeds.
What is the difference between OpenVPN TCP and UDP?
OpenVPN offers two main modes of data transfer: TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
TCP, the more common mode, prioritizes reliability and ensures that data packets are delivered in the correct order. It includes mechanisms for checking for errors and retransmitting lost packets, making it ideal for apps where data reliability is critical, such as web browsing and email. However, TCP is generally slower than UDP due to the additional overhead of error correction and acknowledgment.
On the other hand, UDP is a faster but less reliable protocol than TCP. It does not include mechanisms for error checking or retransmitting packets, which results in higher transmission speeds but can lead to data loss or incorrect delivery. UDP is typically used for real-time tasks such as video streaming, online gaming, and VoIP (Voice over Internet Protocol) where speed is a priority over data integrity. So, TCP is better suited for scenarios that require reliable and streamlined data transfer, while UDP is preferred where speed is of paramount importance, even if it means sacrificing some level of security.
The choice between TCP and UDP in OpenVPN depends on the specific requirements of the user and the expected workflow.
Can I Use OpenVPN For Free?
From a technical point of view – Yes, OpenVPN is free to use. For example, you can use the Community Edition to set up a personal OpenVPN server on your home computer and use the web-based GUI to connect to that server from your mobile device. However, this setup only provides a secure channel to your home and does not offer additional benefits such as IP address masking, censorship evasion, or access to streaming content libraries. To get access to these benefits, you need to subscribe to a VPN service such as ZoogVPN.

By subscribing to ZoogVPN, you get free access to OpenVPN, which can be used either within the app or configured manually. The access to the app simplifies the switch among servers without additional downloads, and offer features such as a No Logs Policy and a Kill Switch.
Why Do You Need OpenVPN?
You may need OpenVPN if you want to create your own VPN server for business or personal use. Additionally, OpenVPN protocol provided by VPN service can be handy for protecting multiple devices at the same time if you install it on a router. However, if you are using a premium VPN provider such as ZoogVPN, you may not need to use OpenVPN directly with manual setup, as the provider’s app is likely to offer a simple interface and different protocols to choose from, with OpenVPN included.
The decision whether to choose OpenVPN or not depends on what you will be using the VPN for. If you’re focused on streaming, gaming, or other bandwidth-intensive activities, speed may be a major priority than security, that is why you need to use OpenVPN. However, if security is of paramount importance, especially when dealing with sensitive data, it is advisable to choose OpenVPN TCP over OpenVPN UDP.
