VPN Protocols

VPN Protocols are the set of instructions and processes between VPN server and the VPN client to make a stable and secure connection. In essence, a VPN protocol is a combination of encryption standards and transmission protocols.

What is VPN Protocol?

VPN protocols are important. They provide safety and speed to your online communications. Whether it is the speed or security depends on the VPN Protocol that you are currently using. These operate as tunnels through which your online traffic can pass through. Some tunnels are secure. Others offer amazing streaming speeds.

There are many types of protocols available, each having different strengths and capabilities. Some protocols are mobile devices friendly. Others can be installed on your Wi-Fi router as well. Some offer better internet protocol security. Choosing a VPN protocol is important if you want to enjoy the best browsing experience.

PPTP vs L2TP vs OpenVPN vs IKEv2 vs SSTP

Selecting the best VPN protocols for your needs can indeed be a headache, but also necessary. There are two different kinds of VPN protocols. One is good for security. The other offers better streaming speeds. None can provide the best of both worlds, though.

A VPN protocol that offers good security is poor with browsing speeds. To understand how this happens, you’ll have to imagine the VPN protocol as a tunnel. When we add more security features, like encryption, it gets narrower. Every packet of data is encrypted first, before it is sent on to the World Wide Web.

In the case of speed friendly VPN protocols, they do not offer security features. These tunnels are wider and your data packets routes in an easy manner. Hence, you receive great streaming speeds.

To help you get rid of the confusion, we present the following chart. It will provide a thorough comparison of different VPN protocols:

Protocol Speed Media Streaming
PPTP Fast Good
L2TP/IPSec Fast Good
IKEv2/IPSec Fast Good
OpenVPN TCP Medium Medium
OpenVPN UDP Fast Good
SSTP Medium Medium

Fastest VPN Protocol For Streaming & Gaming

Connection speeds are closely related to the security provided by your VPN protocol. After all, high-grade encryption not only requires a lot of processing power and time. As a result, it slows down the performance.

If you want to stream at high-speeds, PPTP is the fastest VPN protocol because of its weak encryption. L2TP and IKEv2 are also fast, while OpenVPN and SSTP are slower than other VPN protocols. Winner: PPTP

Most Secure VPN Protocol For Every Device

If we talk about security, PPTP is far from secure. And, it is the last VPN protocol you would want to use to stay safe online. IKEv2 and L2TP are more secure because they encapsulate your data twice.

OpenVPN is the most secure VPN protocol. It offers the highest level of encryption and uses digital certificates for authentication. SSTP also comes with strong security, but it can only be used on Windows operating systems. Winner: OpenVPN

Best VPN Protocol for P2P File Sharing

When it comes downloading, use a protocol that offers good security and speed. While PPTP is the fastest protocol, it lacks security as it uses 128-bit encryption.

Both L2TP and IKEv2 use 256-bit encryption through IPSec. But, L2TP lags behind when it comes to speeds while the latter is not supported on old platforms. Though not as fast as PPTP or IKEv2, OpenVPN still provides speeds and top-notch security. The 256-bit encryption make it the best VPN protocol for P2P file sharing. Winner: OpenVPN

VPN Protocols Explained

PureVPN selects the best VPN protocol on your behalf for a secure and speedy connection. But, it also gives users the convenience of choosing the VPN protocol if they want to. Find out more about the different types of VPN tunneling protocols we support:


  • PPTP - Point-to-Point Tunneling Protocol
  • Due to its basic encryption and low security, PPTP offers a much faster connection. It supports most platforms and is easy to setup. But, is not recommended unless security is completely unessential.


  • L2TP- Layer 2 Tunneling Protocol
  • Since it does not provide strong authentication, L2TP is used with IPSec for security. Though it can struggle with some firewalls, it is a great alternative to OpenVPN protocol. It supports all modern platforms, and can get around ISP/network limitations.


  • SSTP- Secure Socket Tunneling Protocol
  • Owned by Microsoft, SSTP is only available for Windows, FreeBSD, and Linux and cannot be audited. Regardless, it is one of the most secure VPN protocols and has the ability to bypass most firewalls.


  • With fast performance and top-grade encryption, OpenVPN is the protocol of choice. This open-source solution is configurable and runs on any port. As a result, you can get past most ISP/network restrictions and firewalls.


  • IKEv2- Internet Key Exchange
  • Based on the IPSec framework, IKEv2 is the most recent and advanced VPN protocol. Jointly developed by Cisco and Microsoft, it is fast, stable, secure, and very easy to setup. But, there is a lack of support for older platforms

    There are several of VPN services on the web. Some offer more security features. Others offer greater number of IP addresses so you can enjoy greater online freedom. None provide the best of both worlds, except for PureVPN.

    The service offers clients for every device, including smartphones, PC, Mac, and routers. It offers the fastest speeds. And you can connect with over 2,000+ servers in 140 countries via your VPN connection. To get the best out of the internet, PureVPN is the way to go!

    Frequently Asked Questions

    There are three basic types of VPNs, and these include:

    Site-to-Site VPN
    A site-to-site VPN, also referred to as router-to-router VPN, enables offices in multiple locations to safely connect with each other.

    Remote Access VPN
    A remote access VPN allows a user to securely connect to a business or home network and access its resources from a remote location.

    Client-Based VPN
    A client-based VPN establishes a private connection between a user and remote server usually through the use of an application.
    If you are facing issues, you will have to create the following exceptions from your firewall settings:

    PPTP VPN: Open port 1723 for both UDP/TCP.
    SSTP VPN: Open port 1701 for both UDP/TCP.
    OpenVPN: Open port 53 for UDP and port 80 for TCP.
    L2TP VPN: Open port 1701 for both UDP/TCP
