The number of Virtual Private Network (VPN) users is rising sharply daily. Many only subscribe to the services of VPN providers based on technical slogans such as ‘Kill Switch Feature’, ‘Obfuscation Supported’ or ‘Strong VPN Protocols’. In this article, we will highlight the VPN protocols.Maybe you have read on an online forum that a certain VPN service supports L2TP or SSTP. By the end of this article, you’ll be able to distinguish one from the other and the implication of using a VPN that supports a particular protocol with el mejor VPN provider @ Espana.

What is a VPN protocol?

A VPN protocol is a standard that defines how data packets move between your Personal Computer and the VPN server or between the server and a generic device with internet connectivity. The features of existing VPN protocols depend largely on the concerns at the top of the developer’s priority list. As mentioned earlier, some VPN protocols have features that are preferred with respect to connection speed, while some prioritize user security and privacy over all other associated benefits.

It is worth noting, however, that some VPN services have incorporated innovativeness into their VPN applications and servers – using two VPN protocols simultaneously; one for transporting data packets and the other for security and privacy with NordVPN Argentina.

The common VPN protocols

Below are some of the most common VPN protocols.


IKEv2 is a contraction of Internet Key Exchange(version 2). The IKEv2 is a VPN protocol developed by the joint effort of Microsoft and Cisco. The two IKE versions were initially created as a protocol for handshaking data transfers over network connections – that is, for secure AES key exchange, and in combination with IPSec for authentication and encryption of data access.

  • The IKEv2 protocol is not very popular compared to the other common protocols and is mostly known for its mobile VPN applications. It is not news that mobile Internet connections are usually poor and inconsistent. This is exactly the reason why the protocol was adopted for this platform; IKEv2 automatically reconnects if there is a disconnection.
  • Windows, Blackberry, and iOS devices support IKEv2; however, access to the protocol on these platforms is licensed. To use IKEv2 on Android and Linux Operating System, there are third-party applications that enable it with a Nord VPN review Sverige.
  • Der Spiegel, a security analyst, revealed security vulnerabilities of IKEv2 when it showed evidence of NSA spying. However, the exact method of exploiting the protocol’s vulnerability is unknown. IPSec wasïsoleed as the most likely infiltration channel.


PPTP stands for Point-to-Point Tunneling Protocol and is one of the most important protocols in the history of VPN’s. Although PPTP still likes to be used in a few classic network setups, it is mostly archaïsch, but is used as a framework for developing more practical protocols.

PPTP, which was introduced in 1995, has been adopted in the authentication and encryption features of some Microsoft Windows versions. At the time of its creation (the 1990s), PPTP was the success of the day because it supported dial-up connections.
