VPN: definition, use cases, providers, all you need to know!

You arrived here wanting to find out more about a VPN. Well, you have come to the right place. We are going to provide you with all the information you need to learn what a VPN is. We will show you the many uses of it and some of the best providers out there offering the service. So, without any further ado let us get on with it and the first thing we want to get out of the way is what a VPN is.

The definition of a VPN

We are going to explain in as simple terms as possible what a VPN is and how to use it. So don’t worry, even if you do not have technical knowledge you can still follow this guide.

A VPN is a service that you take out via a subscription for a small sum of money each month or pay up front to make the biggest savings yearly.

Once you have taken out a subscription you download a small app to the device you use to connect to the internet. You then install and launch the app and connect to a server from the provider.

When connected to a server through the app your own IP address is masked. You take on one from the server you connected to, while a “virtual” tunnel is put between your device and the internet.


Any information you send goes through the tunnel, is encrypted, and then makes its way onto its destination where it is decrypted. Your information is completely safe on its travels. Even if someone were to come across it, it would be unreadable.

So in conclusion:

  • Virtual – data is encrypted and passes through a virtual tunnel to the internet;
  • Private – with data being encrypted it remains private;
  • Network – all of this takes place through the network of the VPN servers.

Uses of A VPN

A VPN can be used for a wide range of things.

It is an extremely versatile tool and a tool that can be used while at home, when mobile and even when on vacation. This is due to VPN providers offering numerous apps for different devices. This includes computer, smartphone, router and many more. You can find the 5 best uses of a VPN here.


We are now going to talk about some of its varied uses and look at them in more detail, they include:

  • Security
  • Browse anonymously
  • Overcome blocked content
  • Save money (flight tickets, car rental, hotel rooms)

Provides encrypted security

One of the reasons people subscribe to a VPN is for the additional security it provides.

We hear almost on a daily basis of people and companies being breached by hackers and having data, their personal details and money stolen. A Virtual Private Network provides the tools to stop hackers dead in their tracks.

To remain secure using a VPN you can follow the steps below.

Sign up with a provider

The first step is to choose a provider. Once you have signed up with your chosen provider go ahead and download apps for various devices and install those apps.

Launch the app you installed

When you have installed the app click on the icon to launch it and a dashboard will open up. This is where you can access the range of servers offered by the provider. The choice of servers is going to depend on the provider but generally, they will offer hundreds based in many countries around the world. In our example below we chose ExpressVPN as the provider.

ExpressVPN not connected

Choose and connect to a server

Choose a server from the list and connect to that server. Once you have connected you take on an IP address from the server in that country. Along with this a virtual tunnel is put between you and the internet, keeping you secure.

ExpressVPN server choices

Any information that leaves your computer is encrypted as it passes through the tunnel. It remains that way until reaching its final destination where it is decrypted. If anyone does happen to come across it, the information is unreadable as it is garbled and it remains safe and secure.

You can browse anonymously

Another popular use of a VPN is to browse the internet securely. Did you know that even your ISP can check on what you are doing online? Yes, your Internet Service Provider logs everything you do while connected to your internet plan.

This means that if you like to use Torrenting to download movies and software that is copyrighted, they can find out about it. If you download copyrighted content, you are in fact breaking the law. At the very least, your ISP might send you a letter telling you to stop visiting Torrenting websites and downloading content. If you continue to do so, your internet might be restricted and you might even end up in court and receive a fine, or even jail time.

Another way you might want to remain anonymous is freedom of speech. In some countries saying the wrong thing online in forums or on social media for example, can leave you in trouble with authorities or see you being taken to court for slander. With a VPN you can connect to a server from anywhere in the world and browse the web and take part in debates, or report on matters, in total privacy.

Overcome geo-restrictions

A VPN also comes in handy for anyone who wants to overcome geo-restrictions and gain access to content that is blocked.

For instance, you might be located in the USA but travel on vacation to Thailand, China or any other exotic location. If you go to Netflix to try to stream your favourite content you find you are restricted to local content only. As local content does not offer the entire USA Netflix catalogue, you will not be able to stream your saved TV series or movies.

To get around this block you can open up the VPN app on your device. This is assuming that you took out a plan whilst in your home country. It is important to put a VPN in place while at home because the use of VPNs are frowned upon in some countries, China for instance. In countries such as this, you would not be able to visit a VPN website to sign up and download a VPN app.

If you want to access Facebook, Youtube, Instagram, Snapchat on your smartphone, it is the same. You’ll need the best VPN for iPhone if you want to unblock all censored websites.

To get around restrictions just open the app and choose a server based in your own country. In this instance with Netflix, you would choose a US based server from the list and connect to that server.

VPN for streaming

Now wherever you are in the world it looks like you are located in the USA. When you go to the Netflix website or open the app, you can access the entire USA catalogue of content.

The same method can be used to connect and stream from any other streaming website, such as Amazon Prime Movies. You can also use the same method to gain access to any websites or apps that are blocked in any country you visit.

Helps you to save money online

A Virtual Private Network can also help you to save money on such as flights, hotel rooms and car rental. It may surprise you but the cost of flights, hotel rooms and car rental varies depending on the country you are located.

When you make a comparison online the website knows where you are located thanks to your IP address. Each device has its own IP address and countries have a range of IP addresses. When you go to the site the comparison website knows exactly where you are located and shows you prices based on that information.

Change IP address

For instance, you might go online in New York in America to book flights and hotel rooms for a vacation. If you use a comparison site, you will be able to view the cost.

You can make a note of the cost and then log in to the VPN app.  Connect to a server in another state or country with a lower income than your state or country, and search again.

This time the website picks up your IP as being the one in the country whose server you chose to connect and so bases the price on that country. The savings you can make this way might surprise you. You can switch servers numerous times.

For the best results keep clearing your internet browser cache and open and close the web browser every time you try a different server.
