What Is a VPN? How Does It Work? Should I Use One?

The title of this guide says it all! What is a VPN? We are going to explain exactly what a VPN is, how one works, the many uses it has, and why you should use one. So, to find out more about what this service offers, read on.

What Is a VPN?

How VPN works

A VPN is a Virtual Private Network. It is a service that users subscribe to by paying a small monthly fee or paying in advance for a long-term plan. In return, the user is able to connect to the service when using the internet.

A subscription to this kind of service does not mean you do not need an internet connection. You still need your ISP to provide that connection.

What it does mean is that the Virtual Private Network provider offers tools that put a virtual “tunnel” between your computer and the World Wide Web. These tools increase privacy and security online, along with other things.

A VPN not only creates a virtual tunnel but also masks your true IP address and allows you to take on one from the server of your choice, anywhere in the world.

Now we will move on to how this application works and various scenarios in which you might use the service.

How Does a VPN Work?

What is a VPN? How does it work? Well, this type of application has many uses, depending on how you use the internet. From one single subscription plan, you can:

  • Gain access to any geo-restricted content.
  • Browse the internet anonymously.
  • Enjoy security online thanks to military-grade encryption.
  • Make savings when purchasing online.

First, let us look at the very basics of how to use a Virtual Private Network.

Using a VPN

To enjoy everything that a Virtual Private Network offers, you first have to choose a provider, and three that we highly recommend are ExpressVPN, CyberGhost, and NordVPN.

When you have chosen a provider, go ahead and take a look at the plans that it offers. Providers allow you to pay month by month or pay upfront and this is one of the best ways to save money.

For instance, if you choose ExpressVPN, it offers a 49% discount for the 1-year subscription plan, as you can see in the image below.

Doing so, you will get 3 months completely free on top of that. This means that you basically get a 15-month subscription plan at the price of a 1-year plan, which is why we always recommend going for this deal.

Once signed up, you can go ahead and choose apps for devices supported by the provider. There are numerous ones. Apps are typically offered for Windows, macOS, Android, iOS, Routers, and many more platforms.

Besides, you should know that ExpressVPN has the best VPN for iPhone.

Download and install the apps onto your device(s), and then launch the app.

You will then be presented with a dashboard similar to the one below. We have chosen ExpressVPN in our example, so your dashboard might be slightly different. However, the same principle will be behind it.

It allows you to connect to a server offered by the provider.

Choose a server from the list and connect to that server by pressing the “Connect” button.

You have now fulfilled the basics of learning how to use a VPN and you can continue browsing the internet just as you always have, but with added security and many other benefits.

We will continue our “what is a VPN?” guide below by taking a deeper look into the many benefits you get from the service.

Streaming Restricted Content

netflix everywhere

One very popular use of a Virtual Private Network is to unblock geo-restricted content.

Geo-restricted content may be websites that are not available in the country you are located in, or it could be streaming portals such as Netflix.

For instance, if you are located in the USA, you will enjoy the full catalog of the content offered by Netflix. However, if you take a trip outside of the states, you can only gain access to local content, which is severely restricted.

So, what is a VPN? In this case, it is a service that allows you to connect to a server offered by the provider, allowing you to overcome the restrictions. The application does this by allowing you to choose a server from the country whose content you want to watch.

For instance, you might actually be located in London but want to watch the full catalog offered in the US.

Therefore, you would choose a US-based server. After connecting to it, your IP address is masked and you take on an IP address from the USA. When you visit the Netflix site, the site believes you are located in the USA and gives you access to Netflix US.

Browsing Anonymously

Anonymous online VPN

You might not realize it but your Internet Service Provider watches over everything you do online.

They have eyes on you and if you like to use torrent software to download the latest copyrighted movies, music, or software, they can catch you in a heartbeat.

If, or when, they catch you up to no good, they will send out a letter warning you to cease your activities. If you continue, they can restrict or cease providing you with internet service and in the worst-case scenario, you could receive a fine or be given jail time.

With a VPN, you can browse the internet anonymously and use torrent software if that is your thing, without the ISP knowing what you are doing.

The service does this by allowing you to connect to a server of your choice offered by the provider, masking your IP address, and providing you with an alternate one.

Therefore, the answer to what is a VPN in this case is providing a service that allows you to remain anonymous online.

Providing Security

Remain secure

A Virtual Private Network comes into its own working in the background on a daily basis on your computer to provide security and protection.

Once connected to a server, your IP address is masked and you take on an alternate one. Along with this, a virtual tunnel is put between your computer and the internet.

Any information that leaves the computer is encrypted in the tunnel and then goes out onto the internet.

As it is encrypted, the information is garbled so even if someone were to come across it, they would not be able to read it.

Once the information reaches its destination, it is decrypted. This allows you to remain secure all the time, whether undertaking online banking, streaming, or chatting with friends and family online.

Saving Money on Online Purchases

Finally, you can use a VPN to save money online. This is possible as comparison sites base prices on your location using your IP address.

Simply put, you need to mask your IP address with a VPN and take on one from the server in a state or country where the cost of living is lower. You may be surprised at how much you can save on flight tickets, hotel rooms, and car rental.

Is It a Good Idea to Use a VPN?

What is a VPN? In short, an all-around tool that provides you with numerous security and privacy benefits.

So, is it a good idea to use this type of application? We will let you decide.

Without one in place, you risk your information being stolen by hackers. Anyone who shops online or undertakes online banking should give some serious thought to safety.

You do have to pay a small sum of money to subscribe to a provider. However, there are affordable plans. What you pay for is going to be a lot less than what you stand to lose if your computer is hacked and your credit card information or bank account details get stolen.

 You might want to take the risk of torrenting or downloading illegally without a VPN in place. Again, this can be a risk as the ISP can see what you are doing.

A Virtual Private Network provides tools for you to remain anonymous, something that you might also consider if you value freedom of speech.

These are just two of the scenarios in which this application can prove to be valuable. So, ask yourself – is it a good idea to use a Virtual Private Network?

Just as with anything, there are pros and cons, so let us look at them below and weigh them up.

Pros of Using a VPN

We have already talked about most of the pros of using a VPN above, they are:

  • A layer of additional security when browsing online,
  • The ability to browse the internet anonymously,
  • Overcoming geo-restrictions & gaining access to blocked content,
  • Saving money online on hotel rooms, car rental, flights, etc,
  • Downloading torrents anonymously,
  • Bypassing censorship and unblocking blocked sites.

Cons to Using a VPN

So, are there downsides to using a VPN? Yes, but they are minor.

  • A slowdown of your internet connection – This is one thing people worry about and while some Virtual Private Networks may slow your connection, if you choose providers such as ExpressVPN, you will get blazing-fast servers that won’t have any impact on your performance.
  • Some websites and streaming platforms block Virtual Private Networks – Again, this may be true for some providers. However, ExpressVPN is one of the providers who manage to even get around Netflix’s VPN block (it is also the case for NordVPN or CyberGhost).
  • The server connection keeps dropping – This may be something that happens with some low-quality providers but if you choose a provider that offers a “Kill switch” feature, you will be protected even in the case of connection loss simply by putting your internet connection to a halt. Even better, choose a provider that offers reliable connections (3 of them are presented below!).

While there may be some downsides to a Virtual Private Network, these can be overturned, providing you choose a reliable provider.
