Types of VPN Protocols

Virtual private networks (VPNs) are quickly becoming a vital feature in the day to day lives of individuals and businesses. It plays a dominant role in maintaining your privacy, security and anonymity when you access the internet. A VPN is a method of establishing a secure connection to and from a computer or network. It makes use of strong encryption and private, restricted data access which maintains the data secure from other users of the network, especially when you are using a public network. Once you have decided to sign up for a VPN service, the next thing you should decide is about the type of VPN technology to use. To make your choice easier, we have discussed in detail the characteristics of the most widely used VPN protocols in the following sections of this article.

Types of VPN Protocols

The most commonly used types of VPN protocols include the following:

  • PPTP (Point-to-Point Tunneling Protocol): This is the most widely used of all types of VPN protocols. It is also the widely supported method among Windows users and was established by Microsoft along with various other corporations. This networking protocol is developed on the Point-to-Point (PPP) protocol and provides long distance, or remote access for VPN solutions. The main function of PPTP protocol is to ensure that data from one node or computer is transmitted securely to another computer or node. This protocol is usually used for remote access VPNs, as it is available on a variety of machines and is free if you own a Windows operating system.
  • L2TP (Layer Two Tunneling Protocol): The L2TP protocol is a combination of Microsoft’s PPTP and L2F (Layer Two Forwarding). It can support several, simultaneous tunnels at once for a single client. This protocol was developed by a joint effort between Cisco and Microsoft. In addition to providing data confidentiality as that of PPTP, L2TP also provides data integrity, which basically is the protection of your data against customization during its transfer from sender to receiver. It requires a shared key or digital certificate for implementation and is a built-in feature in Windows operating system.
  • IPSec (Internet Protocol Security): IPSec is one of the most popular VPN protocols used for VPN implementations. A robust IPSec protocol has been developed by the Internet Engineering Task Force (IETF), which is being implemented by several vendors. In order to protect the data you transfer over a VPN connection, IPSec determines two major types of transformation: Authentication Header (AH) and Encapsulating Security Payload (ESP). When IPSec integrates with PPTP or L2TP, it provides proficient encryption solutions and offers ultimate security for your data transfer.
  • SSL (Secure Socket Layer): This type of VPN protocol can be used on standard web browsers. In contrary to the conventional IPSec protocol, a SSL VPN protocol does not require the client software installation on your computer.

When you want to use a VPN connection, it is important that you research about all these VPN protocols and choose the one that best suits your needs.
