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. OpenVPN is a mature, widely supported protocol often chosen for reliability and compatibility.
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.
The following chart provides a thorough comparison of different VPN protocols:
| VPN Protocol | Speed | Security | Best For | Available
in PureVPN app |
|---|---|---|---|---|
| WireGuard | Very Fast | Excellent | Streaming, gaming, video calls, everyday browsing |
|
| OpenVPN | Good | Excellent | Privacy, reliability, public WiFi, restricted networks |
|
| IKEv2 | Fast | Very Good | Mobile devices and network switching |
|
| L2TP | Moderate | Fair | Older devices and compatibility needs |
|
| SSTP | Moderate | Good | Windows-based compatibility needs |
|
| PPTP | Fast | Poor | Legacy devices only |

Below is a simple breakdown of the six VPN protocols users still come across today:
WireGuard is 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 is 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/IPSec is 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/IPSec is 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 is 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 is 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.
Not sure which VPN protocol to use? Each option is suited to different situations:
WireGuard is the best starting point for most users. It gives you a fast, modern connection without moving you toward older protocols. Try it first for everyday VPN use, especially if your current protocol feels slow or your VPN takes too long to connect.
OpenVPN is a better choice when stability matters more than speed. It gives you more control through UDP and TCP, which helps when one connection type feels unstable. It is also a strong fallback on public WiFi or networks that block or restrict VPN traffic, thanks to obfuscation.
IKEv2/IPSec makes the most sense on mobile devices. It helps when your VPN disconnects as your phone moves between WiFi and mobile data. For people who travel, commute, or keep a VPN active throughout the day, quick reconnection can make the experience smoother.
L2TP/IPSec, SSTP, and PPTP are not everyday choices anymore. They mainly come up when an older device, router, or manual configuration does not support newer protocols. Use them only when modern options are not available, and treat PPTP as the weakest option.
PureVPN can choose a protocol automatically, but you can also switch it manually when needed. The process is simple and only takes a few steps:
WireGuard is a strong option for most users because it offers a strong mix of speed, security, and everyday stability. OpenVPN is better if you want a longer-tested protocol or need more control through TCP and UDP.
The main VPN protocols users still come across today are WireGuard, OpenVPN, IKEv2/IPSec, L2TP/IPSec, SSTP, and PPTP. WireGuard, OpenVPN, and IKEv2/IPSec are the modern options most people should consider first.
A VPN protocol decides how your request travels from your device to the VPN server before reaching the website you visit. It also controls how the response returns through the encrypted tunnel. A faster protocol may send data with fewer checks, while a steadier one may verify more along the way.
WireGuard is usually the best VPN protocol for gaming because it is fast and lightweight. That said, your ping still depends on your internet connection, the game server location, and the VPN server you choose.
WireGuard is usually faster and simpler to use, while OpenVPN has a longer track record and more connection options through TCP and UDP. For most users, WireGuard is the better everyday choice. OpenVPN is better when reliability or compatibility matters more.
WireGuard is usually the fastest VPN protocol because it is lightweight and built for modern devices. However, speed can still vary based on your network, device, server distance, and internet provider.
OpenVPN UDP is usually better for speed because it sends data with fewer checks. OpenVPN TCP focuses more on reliable delivery, so it can feel steadier on unstable networks but may be slower.
WireGuard and OpenVPN are the strongest everyday choices for security. WireGuard uses modern encryption, while OpenVPN has a longer history and broad support. PPTP should be avoided because its security is weak by modern standards.
No, PPTP is not a safe choice for privacy or secure browsing today. It is fast, but mainly because it uses weak security. Use it only in rare cases where an older device does not support newer protocols.
WireGuard is usually the best VPN protocol for streaming because it is fast and efficient. It can help with smoother playback, but your base internet speed, server distance, and streaming service can still affect performance.
Most users leave protocol selection on automatic, so PureVPN chooses a suitable protocol for the connection. If you want to test another protocol for speed, stability, or compatibility, you can manually switch between the available options.
