Types of VPN Explained: OpenVPN, WireGuard, IKEv2

Tap an item to see what it means.

What Is a VPN?

A technology that routes your internet connection through an encrypted virtual tunnel, hiding your real location and data from outside observers.

OpenVPN

Open-source and security-vetted, with a strong balance of speed and stability, making it the most widely used VPN protocol.

WireGuard

A relatively newer protocol with much leaner code, known for fast speeds and low battery consumption.

IKEv2

Reconnects quickly after a dropped connection, making it especially well suited to smartphone use where you frequently switch between Wi-Fi and mobile data.

Remote-Access VPN

Connects an individual's device to a company's internal network, letting remote workers securely access company resources.

Site-to-Site VPN

Securely connects a company's multiple branch office networks in different locations into a single unified network.

Protocol Choice Affects Speed and Security

Even within the same VPN service, the underlying protocol used can significantly affect connection speed and stability. The right protocol also depends on your purpose β€” accessing your company network while working remotely calls for a different setup than using a VPN purely for privacy.

Frequently Asked Questions

Does using a VPN slow down my internet?

Routing data through an encrypted tunnel can cause a slight slowdown, but newer protocols like WireGuard are designed to minimize this impact.

Is it safe to use a free VPN?

Some free VPNs actually collect and sell user data, so it's important to check whether you're using a service from a trustworthy provider before relying on it.
