How does a VPN work?

A virtual private network (VPN) is a useful tool that will hide your tracks when you’re online and help you bypass some websites that have regional restrictions. While you may already know what a VPN is and how it works, we’re going to look at how they work.

A VPN redirects your internet connection to a remote server managed by the VPN provider. This creates the illusion that you are browsing from a different location than your actual location. Because all communication between you and the server is encrypted, your ISP can’t detect what you’re doing. This results in an encrypted connection that masks your true location and protects your personal information.

The benefits of this may be obvious, but there are pros and cons to setting up a VPN that you should be aware of. Let’s take a closer look at VPNs to find out if they’re the best tool for you and when you should avoid them.

VPN basics

VPN basics

First, let’s take a look at how internet connections work to understand what a VPN does. To read an article like this, your computer will send an inquiry (or request) to the ISP server. The server then forwards the request to the Expert Reviews server, which sends back information for that page.

A VPN requires an extra step. Your computer asks your ISP to connect to a VPN server, which then forwards your request to the website you’re looking for. Expert Reviews believes that the request is coming from the server’s IP address and not yours.

It has two advantages. It gives you the appearance of being somewhere else in the world, which is fantastic if you’re trying to beat geo-restrictions. You can use a VPN to connect to your bank account abroad or to access regional Netflix libraries.

Companies and websites can track you online if you browse through an encrypted VPN server. Many methods are used to track your IP address to identify you so that when you connect to another address they think you are not. However, there are other ways they can track you, which we will talk about in the future.

Encryption and protocols

Encryption and protocols

A VPN can also redirect your connection. Your VPN software uses strong encryption to encrypt outgoing data packets. The remote VPN server can decrypt the packets and forward them to the destination. Your ISP can’t see the destination of the transaction because encryption prevents it from being there. This type of connection is often called a VPN tunnel because, similar to tunnels through mountains, anyone watching your connection can see you go in, but they won’t be able to see where you come out or what you do while you’re in it.

VPN sites often advertise the use of military-grade encryption as an encryption method. This is a fancy way of saying that they use the same type of encryption as most militaries, called AES-256. It’s extremely powerful, but there are other options like AES-128 and Blowfish that work just as well.

This encryption is what turns “private” into a “virtual private network”. While many internet-based systems can redirect traffic, encryption allows a VPN to do more than other programs. It can bypass censorship restrictions such as those enforced by China or avoid detection by persistent followers.

VPN protocols

More important than the encryption you offer is what protocols your VPN uses. Although the details are complex and technical, the fact is that a protocol is a set of rules that govern how devices communicate with each other. The protocol governs the encryption methods used in VPNs. Some other factors can also affect performance.

We generally recommend OpenVPN because it offers high security and speed. There are other options like Wireguard that you could consider. Some of the best VPNs use custom protocols, such as NordLynx NordVPN or Lightway ExpressVPN.

What a VPN can’t do

What a VPN can’t do

A VPN can magically get you wherever you need to be while keeping your connection secure – but there are some downsides to using a VPN that providers won’t always let you know about.

One of the biggest problems is that a VPN can slow down your internet connection quite a bit in some cases. The further away your chosen server is, the more likely it is to slow down. Although the most effective VPNs like NordVPN or ExpressVPN can only slow down your connection by 10% when connecting to US servers, it can still be noticeable, especially if you have a slower internet connection.

While VPNs can block certain tracking methods, there are still many ways for websites to see what you do online. For example, browser cookies can still be used to see what you’re doing, VPN or not, as well as a technique called browser fingerprinting, which profiles your browser configuration, browsing habits to create a unique profile of you. Private browsing, also known as incognito mode, is better than using a VPN to protect against such security measures.

Despite these limitations, VPNs help far more than they hurt, both in terms of privacy security and spoofing. If that sounds good to you, check out our full reviews of all the major VPN packages, with our top picks NordVPN and ExpressVPN. Have fun and stay safe out there!
