VPN Protocols

VPN Protocols are the set of instructions and processes between a 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.

VPN Protocols

What is a VPN Protocol?

VPN protocols are important. They provide safety and speed to your online communications. Whether your VPN is optimized for 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 device 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.

Which VPN Protocol Should You Use?

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.

Any VPN protocol that offers good security will be weaker when it comes to browsing speeds. To understand how this happens, 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.

Speed-friendly VPN protocols, do not offer security features. These tunnels are wider and your data packets route in an easy manner. Hence, you receive great streaming speeds.

The following chart provides a thorough comparison of different VPN protocols:

Fatest VPN Protocol

What Is the Fatest VPN Protocol?

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. Connection speeds are closely related to the security provided by your VPN protocol. After all, high-grade encryption requires a lot of processing power and time. As a result, it slows down the performance. Winner: PPTP

Most Secure VPN Protocol

What Is the Most Secure VPN Protocol?

If we talk about security, PPTP is far from secure. It is also 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.

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. However, L2TP lags behind when it comes to speeds while IKEv2 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 makes 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. We also give our users the convenience of choosing the VPN protocol if you want to.

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. That said, it 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 may conflict with some firewalls, it is a great alternative to the OpenVPN protocol because 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.

OpenVPN – Open-Source Protocol

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. However, since it is new, there is a lack of support for older platforms.

IPSec – Internet Protocol Security

IPSec is a set of protocols used for various purposes, including securing VPNs. It is usually paired with VPN protocols like IKEv2 and L2TP to provide data confidentiality (encryption) and authentication, but can be utilized as a standalone VPN protocol as well.

Other VPN Protocols

These VPN protocols are discussed for information purposes only and are not offered by PureVPN.

SSL/TLS – Secure Socket Layer

SSL and its successor TLS are the most commonly used cryptographic protocols today. Every time you visit an HTTPS website, SSL or TLS secures your connection with the server. It is used in VPN protocols like OpenVPN for encryption, but is not a VPN protocol by itself.


WireGuard is the newest VPN protocol on the block. Meant to be a replacement of IPSec, it is allegedly lighter and faster. Furthermore, it is open source, which means a reduced likelihood of security vulnerabilities. However, the protocol is still under development and lags behind in terms of cross-platform compatibility.


SoftEther is fairly new in comparison to other VPN protocols (excluding Wireguard). It’s quickly gained popularity because it’s very secure, stable, and fast. The protocol works with most operating systems (including Solaris and FreeBSD) and even has functionalities that OpenVPN doesn’t offer, like GUI Management and RPC over HTTPS, to name a few.

FAQs – VPN Protocols

What are the types of VPN?

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.
