This article briefly explains these differences, so you can comfortably select VPN tunnel protocols that best suit your needs. Knowing the right choice to opt for also matters a lot, depending on the gadgets you are planning to choose for data connections.

What is a VPN Protocol?

In computing, a protocol refers to an agreed language that a machine use to communicate with another machine. VPN tunnels refer to the protocols that maintain computer connections, while providing encrypting and decrypting functions to ensure that your data is safe. Protocols may also vary as there are different ways in which data encryption and decryption is performed.

The PPTP Tunnel Protocol

This stands for Point-to-Point Tunnel Protocol, the simplest protocol of the three protocols available. It is a fairly secured protocol, but it only works on a 128-bit data encryption. This presents minor vulnerabilities like risks of disconnection, which provide opportunities for snooping.

This is also easily detected by China’s Great Firewall, making it possible for the country to block your VPN connection. However, its main advantage is that it is quite fast due to the fact that 128-bit encryption does not slow down your bandwidth speed.

The L2TP-IPSEC Protocol

Unlike the PPTP, the Layer 2 Tunnel Protocol runs on a 256-bit encryption and is relatively slower. However, this is strengthened when combined with an IPsec protocol to provide additional privacy, authentication, and integrity in the connection. This is a good choice if you are looking for high-level security, as well as good ability to bypass restrictions.


This is a superior VPN tunnel protocol, offering several advantages over the other two mentioned above. Like other top web tools, this is an open source protocol that is constantly undergoing development. This has very good stability and works perfectly over wireless connections.

The OpenVPN is particularly important if you are planning to deploy your UK VPN with online purchases as this also incorporates SSL security protocol, which is universally-applied in e-commerce – ensuring the security of online purchases, online banking, and transfer of ultra-sensitive information.

The advantage of this protocol is that it can be applied world-wide, ranging from Windows to Mac environments. For the best UK VPN server network with fast VPN servers, along with the best encryption and security features for your data, visit
