First of all, what is VPN Protocol?

A VPN protocol is basically a mix of transmission protocols and encryption standards. Also known as cryptographic protocols, they determine the level of encryption.

VPN is standing on the side of your protection preventing data leaks. It is a tool created to protect you from various online security breaches.

Each protocol has its own pros and cons. The pluses, of course, a possibility to maintain a higher level of privacy and provide users with a better speed.

The world is constantly changing and data protection approaches are also changing. Some technologies may become unreliable and considered as outdated.

 

What VPN protocol types exist?

The most popular tunneling protocols are:

  • – OpenVPN
  • – IKEv2
  • – PPTP
  • – L2TP/IPSec
  • – SSTP

 

Of these, the following protocols are no longer relevant:

  • – PPTP
  • – SSTP
  • – L2TP/IPSec

 

If to compare all the protocols, very fast and stable protocol I would recommend to choose – IKEv2 and OpenVPN.

Let’s learn more about these two protocols.

 

OpenVPN protocol

OpenVPN is well-known as an open-source tunneling protocol.

OpenVPN offers various internal security features. It has up to 256-bit encryption through OpenSSL library, although some service providers may offer lower rates, effectively providing some of the fastest VPN available to consumers.

 

IKEv2

IKE (Internet Key Exchange) is the method of authentication and is considered to be a secure tunneling protocol. IKEv2 (version 2) is a VPN encryption protocol that handles request and response actions, offers strong encryption with a variety of options for security.

Funnily enough, IKEv2 is not technically a VPN protocol, but it does behave like one, and it helps control the IPSec key exchange.

 

So, what is the best option? OpenVPN uses strong ciphers and TLS (Transport Layer Security) – at the present moment, it is considered to be the strongest encryption. OpenVPN uses SSL/TLS for it’s a secure protocol which secures data at the Transport level, while IKEv2/IPSec secures data at the IP level.

 

There are also two more types of protocol I would like to introduce you – SmartUDP and SmartTCP. Using any of these protocols you will get the feet wet how VeePN cares about your data and strongly promotes your right for anonymity.  

 

What is VeePN SmartUDP?

It is the protocol implemented based on the OpenVPN protocol for UDP (User Datagram Protocol) that uses the improved XOR encryption algorithm. Easy to apply, very lightweight – undoubtedly, the advantages of SmartUDP. A very secure protocol using 256-bit encryption and high-end ciphers. Gets past most firewalls and ISP restrictions. As for disadvantages, it is not supplied by some mobile devices and requires installation of 3rd-party software.

 

What is VeePN SmartTCP?

It is the protocol implemented based on the OpenVPN protocol for TCP (Transmission Control Protocol) port that also uses the improved XOR encryption algorithm. Its pros are easy configuration, highly secure protocol using 256-bit encryption keys and high-end ciphers. Talking about its cons, the protocol does not have congestion control and it is not supplied by some mobile devices.

 

Exclusively for VeePN users SmartTCP and SmartUDP protocols are supported on lots of platforms that you might need. All data will be encrypted using the most advanced methods.
