What Are the Different Types of VPN and How Do They Work?

A VPN (Virtual Private Network) lets you surf the internet while protecting your privacy. It creates an encrypted tunnel between your system and the remote server. Thus, it hides your online activities and your IP address.

There are four major types of VPN. These include personal, site-to-site, remote access, and extranet-based site-to-site VPN. This post will familiarize you with VPN, its types, and how it works.

How Does a VPN Work

A VPN masks your IP address. It does so by making the network redirect your IP address via a specially configured remote server. A VPN host runs this server. So, if you stream content online with a VPN, its server becomes your data’s source. Thus, neither your ISP nor any third party can see the sites you are accessing. They also cannot see the data you exchange online.

Why Should You Use a VPN?

There are many reasons to use a VPN. Protection against identity thieves is its major benefit. But there are many other ways in which it helps improve your online surfing. From hiding your activities from government surveillance to bypassing censorship, the reasons are many. Here’s a detailed explanation of these reasons. 

  • Hide yourself from government surveillance: A VPN keeps your online activity private. So, your web searches, browsing history, and emails cannot be monitored by government agencies.
  • Avoid government censorship: Websites like Twitter, Facebook, and Wikipedia are blocked in many countries. A VPN changes your IP address and encrypts the web traffic. So, you can bypass censorship of the internet.
  • Protect your data: Sometimes, malicious users can gain access to your private information. A VPN keeps the sensitive information you share safe. It encrypts this data going through the servers of malicious users.
  • Unlock geo-restricted services: Services like Hulu BBC iPlayer, among others, aren’t available everywhere. If you want to access such a service in your region, a VPN will help you. It fakes your location so you can access these services.

The Different Types of VPN

A site-to-site VPN technology sets up secure connections between several remote networks. It is one of those types of VPN that businesses use. It lets them link various locations into one private network. This single network is called an intranet.

Every location has its specific local area network called LAN. This LAN has varying IP ranges. A site-to-site VPN technology interconnects LANs securely. It, in turn, enables smooth communication between them.

This type of VPN is ideal to protect data from unauthorized access. 

  1. Extranet-Based Site-to-Site VPN

To have secure communication between several organizations, an extranet-based site-to-site VPN is used. This technology involves business partners, customers, or suppliers. Every organization has its own internal network.
