VPN Protocols
A VPN protocol controls how your VPN connection works. It affects speed, stability, and how your data moves through the encrypted tunnel. Compare WireGuard, OpenVPN, IKEv2, L2TP, SSTP, and PPTP to see which one fits your needs.

What Is a VPN Protocol?
A VPN protocol is the rulebook your VPN app follows when it connects your device to a VPN server. One protocol may be better for speed and another might hold up better on unreliable networks. There are some older options too, but they only make sense when a device does not support newer ones.
Protocols Comparison
The following chart provides a thorough comparison of different VPN protocols:
Types of VPN Protocols Explained
Below is a simple breakdown of the six VPN protocols users still come across today:
WireGuard
WireGuardis a modern VPN protocol built for speed and strong security. It uses ChaCha20 encryption and has a leaner codebase than older protocols, so it runs efficiently on everyday devices. It is a good fit for streaming, gaming, video calls, browsing, and downloads. Some users may still prefer OpenVPN due to its longer track record.
OpenVPN
OpenVPNis a widely used, open-source VPN protocol known for its reliability. It uses AES-256 encryption and can run over UDP or TCP. UDP is usually better for speed, while TCP can feel steadier on unreliable networks. It is often used for public WiFi, restricted networks, and manual VPN configurations.
IKEv2
IKEv2/IPSecis a fast and stable VPN protocol, especially on mobile devices. Its biggest strength is reconnection. When your phone or tablet switches between WiFi and mobile data, IKEv2/IPSec can help the VPN reconnect quickly instead of dropping the session completely. People who move between networks often may find it useful.
L2TP
L2TP/IPSecis an older VPN protocol pairing still found in some manual VPN configurations. L2TP creates the tunnel, while IPSec helps secure the connection. It is more secure than PPTP, but it is no longer a top choice compared with WireGuard, OpenVPN, or IKEv2/IPSec. Most users only need it when an older device or network does not support newer protocols.
SSTP
SSTPis a Microsoft-developed VPN protocol often linked to Windows environments. It can help in specific compatibility cases, but it is not as common in modern VPN apps as WireGuard, OpenVPN, or IKEv2/IPSec. Most users will not need SSTP unless an older Windows-based system or manual configuration requires it.
PPTP
PPTPis one of the oldest VPN protocols still mentioned today. It is fast, but mainly because it uses weak security by modern standards, which makes it a poor choice for privacy, public WiFi, or secure browsing. PPTP only makes sense in rare legacy cases where a device does not support newer protocols.
