Choosing a VPN Service: What Protocol Does OpenVPN Use?

When selecting a VPN service, the array of choices can be overwhelming. This article guides you through the essential considerations to keep in mind, starting with a fundamental question: What protocol does OpenVPN use? Understanding this and other critical aspects will help you make an informed decision.

What is OpenVPN and Which Protocol Does it Use?

OpenVPN is one of the most popular VPN protocols in the industry, known for its balance of security and performance. It utilizes SSL/TLS for key exchange and is capable of traversing firewalls and proxy servers. OpenVPN allows peers to authenticate each other using pre-shared keys, certificates, or username/password combinations. Its flexibility in authentication methods makes it a robust choice for a secure VPN.

Key Factors to Consider When Choosing a VPN

Security Features

Security is the cornerstone of a reliable VPN service. Evaluate what security protocols are offered by the VPN provider. Besides OpenVPN, look for support for protocols like IKEv2/IPsec and WireGuard, which offer advanced encryption standards and faster speeds.

Encryption Quality

The strength of encryption determines how well your data is protected. A VPN that offers AES-256 encryption—the same standard used by the U.S. government—ensures top-notch security.

Privacy Policy

Understand the VPN provider’s logging policy. A strict no-logs policy means that your online activities, such as browsing history, data content, and connection times, are not recorded, further enhancing your privacy.

Speed and Performance

The performance of a VPN can significantly affect your internet experience. Factors affecting speed include the server location, server load, and the VPN protocol used. Providers with a broad range of servers globally usually offer better speed and reliability.

Ease of Use

A user-friendly interface is crucial, especially for those new to VPNs. Look for services that offer easy-to-navigate apps for multiple devices.


VPN services vary widely in price. Assess whether the features provided justify the cost. Most providers offer different plans, including monthly subscriptions and longer-term options at a discount.

Customer Support

Reliable customer support is essential. Ensure that the VPN provider offers multiple support channels such as live chat, email, and a comprehensive FAQ section.
