A VPN is useful for increasing your privacy, security, and freedom on the Internet, but have you ever wondered how many types of VPN there are? These tools come in many different forms, which is why it can be difficult to decide which one best suits your needs.

In this guide, you will learn about the many types of VPNs as well as the security protocols on which they are based. We also give you an overview of several VPN services available today for the average internet user.

Let’s dive into:

3 main types of VPN

A VPN creates a private tunnel between your device and the public internet. All of your traffic is encrypted as it passes through this tunnel, keeping your personal data safe from ISPs, government surveillance, hackers and other entities. These tools can be divided into three main types:

1- Remote Access VPN

Remote access VPNs are the most popular type of VPN these days. Essentially, these connect users to a remote server located in another country. Most commercial VPN services are built on this foundation! They allow you to surf the Internet using their own network, encrypting the data you send and receive in the process.

As a result, you can use the Internet in complete privacy, access websites and content otherwise restricted in your area, and protect your data from prying eyes on public and private networks. This type of VPN is ideal when it comes to personal use, and may not be suitable for corporate purposes.

2- Site-to-Site VPN

Site-to-site VPNs work differently; It allows companies with offices in multiple fixed locations to establish secure communications between each other over the Internet. Here is an example for your better understanding: You work in the San Francisco branch of a large corporation and would like to collaborate with employees of the Toronto branch.

With a site-to-site VPN, it becomes possible to share information and resources with each other. This type of VPN is suitable for large scale business environments that require private communications between offices around the world. However, it is impossible to implement it without specialized equipment. Site-to-site VPNs can be divided into two types:

Intranet VPN

A company with multiple remote locations can quickly and securely communicate with each other by creating an intranet VPN. This connects each LAN to a single Wide Area Network (WAN).

Extranet VPN

A company that has business relationships with other companies can create an external VPN to connect the private local networks to each other. This allows all parties to work together in a shared network environment while restricting access to their intranets.

3- Client-based VPN

Client-based VPNs connect users to a remote network via an application/client that handles the creation and connection of the VPN. To access the secure connection, the software must be run and authenticated with a VPN username and password. This is how the encrypted link between the device and the remote network is built for secure data exchange.

As far as client-based VPN implementation is concerned, operating systems like Mac, Windows, Android, and iOS also come with the option to manually configure the encrypted connection based on a variety of criteria. You can choose between SSTP, PPTP, L2TP, and more.

The different types of VPN services available

VPN providers may have different types of services on offer based on the customer base they are targeting. We have divided these into several categories according to the following criteria for your better understanding: scalabilityAnd Protocol AvailabilityAnd privacy protection level, And price range.

VPNs for personal or business use

Business VPNs are designed to meet the requirements of large businesses and make it easy to set up, deploy, and manage VPN connections. On the other hand, personal VPNs are geared towards serving the needs of individual users, although they can sometimes cater to small businesses as well.

Single and Multiprotocol VPNs

Most of the VPN services available offer support for multiple protocols such as IKEv2, OpenVPN, and WireGuard, which gives you plenty of options for establishing a VPN connection. Others prefer to provide support for a single protocol, especially OpenVPN, because it is open source and is considered the most secure option currently available.

Unregistered VPNs and more

When it comes to privacy protection, users have two types of VPN services to choose from: those that don’t store any logs and those that do. Unregistered or no-logs VPNs do not collect, store, or share sensitive data regarding your bandwidth or connection, and their privacy policies are certified by independent third-party auditors.

Other VPN providers keep minimal logs and highlight this in their privacy policies. This does not necessarily mean that they are unreliable, but these VPN services are not ideal if complete privacy is important to you. As a general rule, avoid providers who make big promises despite having a poorly written vague privacy policy.

Free, Budget, and Premium VPNs

As far as the price range goes, VPNs are usually divided into the following categories: free, budget, and premium.

Premium VPNs cover all the bases and provide a good blend of performance, security, and privacy along with must-have features like a kill switch, DNS leak protection, and split tunneling. They also have easy-to-use apps for all platforms and helpful customer support via live chat. All this makes the prices of these VPNs very expensive.

On the other hand, reasonable price is often the biggest strength of budget VPNs. Some provide services that are good enough to be considered outstanding in a few aspects, usually essential. When it comes to free VPNs, they are suitable for occasional use but not reliable from a security and privacy point of view. Additionally, most of them have limitations such as limited servers and bandwidth.

7 common types of VPN protocols

The three VPNs described above are based on a range of security protocols, each with their own advantages and disadvantages. These include:

  • PPTP
  • L2TP
  • SSTP
  • OpenVPN
  • IKEv2
  • IPsec
  • Wireguard
