How a VPN works and why you should use one?

A Virtual Private Network (VPN) is one of the most useful tools available out there. It helps you protect your privacy and security on the Internet. In fact, it can even enable you to evade censorship and geo-restrictions that prevent you from accessing your favorite websites and services.

However, that’s not all a VPN can be used for. In the coming paragraphs, we’ll take a quick look at how a VPN works and other important reasons for using one. So, let’s get started:

How a VPN Works?

The main function of a VPN is to keep you secure when you are connected to the Internet. Usually, when you try to access a website, traffic from your device is sent to the website’s server. But since it is unencrypted, third-parties are able to keep track of you.

When you connect to a VPN, an encrypted connection – also commonly known as a tunnel – is established between you and the Internet. All you traffic is routed through this tunnel to the VPN server, which then passes it on to your intended destination.

As a result, nobody will be able to see or tell what you are doing on the Internet. It becomes close to impossible for ISPs, governments, and advertisers to tie your online activities back to you as your original IP address also gets changed in the process.

Why Should You Use a VPN?

Now the question is, why you should use a VPN? Well to help you understand this, let me just point out some of the top benefits of VPNs:


Privacy is vital to us, and we cannot deny this. In real life, we are always careful with our privacy. But when we are online, we don’t pay much attention to privacy. You should know the fact that ISPs can easily track what kind of websites you are visiting online.

However, with a VPN, you can stop your ISP and other prying eyes from spying on you with IP address masking and military-grade encryption.

Access Geo-Restricted Content

Have you ever been unable to access certain content on the Internet? Well, that’s because of geo-restrictions. For instance, you won’t be able to access the American version of Netflix if you are living in the UK or Canada.

You can only do that with a US IP address only, and this is where a VPN comes into play. By connecting to a US VPN server, you can replace your real IP address with an American one to dodge these roadblocks and access the content on US Netflix.

The same concept can also be applied when it comes to accessing other services such as Foxtel, for example. Using a VPN, you can quickly get an Australian IP address to access and watch the content available on the streaming platform.

Using Public Wi-Fi Safely

Another huge benefit of a VPN is that it allows you to use any public Wi-Fi without any risk. These networks can leave you susceptible to data theft because of their open nature. However, by using a VPN, you can secure all the traffic to and from your device with AES 256-bit encryption. If you regularly use open Wi-Fi hotspots, it’s highly recommended that you buy a VPN to keep your personal information safe and sound.

Final Words

While the benefits of a VPN are many, the truth is not all of these tools are created equally. Some are great for accessing content, others are suitable for torrenting anonymously. PureVPN, on the other hand, offers the best of all words and its high rating on Trustpilot is a testament to this fact.
