Types of VPNs and their Protocols

A VPN, or Virtual Private Network, is a special tool that allows users to use the network connection secured by the VPN provider. Your data is routed through that server, making it appear as if you are connecting from the server’s location rather than your actual location.

This can be useful for:

But with so many different types of VPN and protocols on the internet, it can be hard to know which one is right for you. In this article, we’ll take a closer look at the different types of VPNs and their protocols, so you can decide which is right for you

Types of VPNs

There are four types of VPN:

  1. Site-to-Site VPN.
  2. Remote Access.
  3. Wireless VPN.
  4. Mobile.

Each type of private network is used for different tasks. For example:

  • A wireless VPN is one of the types of network when a user connects to a private network from anywhere on the planet. This approach provides a secure and convenient connection to your own internal network.
  • Remote access is a type of VPN that gives users the ability to use the VPN from a distance. For example, such systems are often used by companies and individuals so that their employees can connect to a VPN from a remote location.

ADVICE! In addition to VPN, you can also consider another type of connection for viewing a large amount of data and files. Consider using cloud storage to make anyone you give edit access to can view your files, upload or modify them. Popular among many services are Dropbox and GoogleDrive. They are easy to use, their interface is simple enough to learn, and the registration does not take more than five minutes. In addition, cloud storage also offers protection for your data and provides all the necessary tools for work.

  • Mobile. It’s a type of VPN that allows users to join private networks using their phone or tablet. This solution is often popular among companies that use mobile devices while working with their networks.
  • Site-to-Site is a type of VPN that connects two places, such as two offices or two networks. Companies or organizations in multiple locations often use this type.

What Does a VPN Protocol Mean?

VPN protocols are the methods by which data is routed through a connection. There are six main types of VPN protocols. But before we get closer to protocols, we should deal with functional approaches to VPN.

There are two main approaches to VPN functionality:

  1. The first and more secure uses two valid protocols. One of them is responsible for protecting your data, and the second – for its movement through an encrypted tunnel.
  2. The second method is less secure, since VPN uses one protocol that performs protective and transport functions at the same time.

Types of VPNs Protocols

Types of VPNs Protocols

Each type of VPN uses different protocols to route data through the connection. The six main types of VPN protocols are:

  1. Point-to-Point Tunneling Protocol (PPTP).
  2. Layer 2 Tunneling Protocol (L2TP).
  3. Internet Protocol Security (IPsec).
  4. Secure Sockets Layer (SSL).
  5. OpenVPN.
  6. Secure Shell (SSH).

Now let’s consider them in detail:

  • PPTP uses the PPTP cipher to create the tunnel. Unfortunately, this one is not secure and can be easily hacked. As a result, it is not often used in devices. Instead, programmers prefer to use more secure and sophisticated encryption protocols that can provide the required level of protection.
  • L2TP works like this: it creates a reliable tunnel between two connection points. After that, it uses a different protocol to mask your data. For example, IPSec.
  • IPSec is a very strong security measure because it uses double encryption technology. Your data is encrypted into a data packet, and then it is also encrypted one more time.
  • SSL protocols are often used in browsers to encrypt HTTPS. It is quite easy to use, as no settings are required. Many browsers have this feature by default.
  • OpenVPN is an improved version of SSL. It has more powerful encryption capabilities and makes your internet experience even more secure.
  • SSH is often used for remote access because it allows you to send data to remote devices.

Now you know the answer to the question ‘What does protocol mean?’ and can go to the pros and cons of every one of them.

Advantages and Disadvantages of VPN’s Protocols

Advantages and Disadvantages of VPN’s Protocols

Each protocol has its advantages and disadvantages. PPTP is the most simple VPN protocol and is very easy to set up. However, it is not as secure as other VPN protocols because it does not use encryption. L2TP is more secure than PPTP because it uses encryption. However, it is more complex to set up. IPsec is the most secure VPN protocol because it uses encryption and authentication. However, it is very tricky to set up. SSL is a very secure VPN protocol that is easy to set up.

However, you must choose the right VPN protocol for your needs. Follow the basic principles:

  • If security is your main concern, you should use IPsec. 
  • If you are worried about ease of use, consider using PPTP. 
  • If you need a VPN protocol that is both secure and easy to use, you should use SSL.

In general, there are plenty of controversies and disadvantages as well as positive sides and advantages over other private network services. Your VPN choice should look like you push your way through a tough jungle of modern, advertised services that guarantee performance, speed and connection results. 

To get precisely that result, you should test a lot of instruments until you find one that is the best for you. To test your instrument with no risks to your device, you can use a virtual machine*.

*A Virtual Machine (VM) is a computational resource that runs programs and deploys apps using software rather than a real machine. A physical “host” machine hosts one or more virtual “guest” machines. Even when they are all running on the same host, each virtual machine has its operating system and works independently of the others. This implies that a virtual macOS machine, for example, may be launched on a physical PC.

Bottom Line

Now you understand that choosing a VPN is not so easy. First of all, you need to set yourself the tasks with which your tool must cope. Then you shoul determine what your budget is for purchasing the plan. And after that, you need to choose the best VPN among all their different types.

But remember that the safety of your device and data comes first. When testing a VPN, make sure that you are not connected to an open Wi-Fi and do not use sensitive data in your work.


  1. Which type of VPN is best?

    Many VPN experts recommend OpenVPN as the most secure protocol. It uses 256-bit encryption as a default but offers other ciphers such as 3DES.

  2. What is the most common type of VPN?

    Remote Access VPNs are the most popular type of VPN these days. They connect users to a remote server located in another country.

  3. What is a VPN?

    A VPN, or “virtual private network,” is a service that protects your internet connection and online privacy. It creates an encrypted tunnel for your data, protects your online identity by hiding your IP address, and allows you to use public Wi-Fi hotspots securely.

  4. Why should one use a VPN?

    A VPN creates a private tunnel so hackers, your ISP, and the government can't see what you're doing. But, even at home, a VPN can help protect you from other privacy threats.
