Why do you need a VPN? The benefits of having one!


You can’t go online recently without becoming aware of the need to protect your privacy. Protecting your privacy and securing your personal data online have become the number one concerns surrounding online life and our dependence on the internet. 

Your Internet Service Provider, ISP, is not your friend, and in many jurisdictions around the world ISPs are working in conjunction with local laws to make your data available to government snooping. And that’s just the tip of the iceberg. Your data is possibly compromised at every point along it’s journey from you to it’s destination, and this is a major concern for many. 

There are ways to alleviate the issue though, and one of those is to secure your internet connection with a VPN. A Virtual Private Network can go a long way to alleviating these privacy concerns. Used correctly a VPN can help to protect you anonymity online. 

  • How A VPN Works 

When you use a messaging application such as WhatsApp on your phone, you are using a service that employs something called end-to-end encryption. This encryption means that anyone who tries to snoop on your conversation will not be able to read the contents of the message. Only the intended recipient can decode the message to read it. 

That’s an incredibly powerful tool to have. Encryption like this means that messages can be send that are completely secure. You don’t have to worry about anyone intercepting the message because they will not be able to read the contents of the message anyway. 

This is exactly what A Virtual Private Network, or VPN does for your internet connection. When you go online protected by a VPN, you create a connection between your computer and the VPN server. This connection is protected and private. It is protected by a ‘key’ that only your computer and the VPN server know. This key is used to lock all of the data that you send. 

Let’s say you want to view a web page. Your request makes it’s way to the VPN server, the server will then ask the website or web resource for its data. This is sent firstly to the VPN server and then from there to your computer. 

Your VPN server does not encrypt the data between it and the web page. It doesn’t have to. It’s job is to create anonymity. That anonymity was created by encrypting the data between you and the VPN. 

Now what the server does is encrypt the data again and send it to your PC. 

To the remote web page, it just served data to a request made somewhere on the web. 

To you and the VPN server, data was anonymously read from a web page and securely transferred to your computer without anyone else knowing that it was you. 

  • What A VPN Can Do 

A VPN can protect your privacy online, but what does this mean? 

Well, many web sites around the world make use of the many tracking tools that are available online. These tracking tools mostly are there to help the website owner gain insight into the kind of traffic that their website gets. This knowledge can help them to tailor the content on their site and to see how users interact with the site. 

Tracking tools such as these are commonly provided by large internet firms such as Google. 

However, this means that when you visit a website, identifying details about your computer are passed to the remote website. 

Once that has happened, then your visit has been logged. Your computer OS, screen resolution, network details, and a host of identifying information are given to the remote server. These details can be used to identify you when you go to other websites as well. Thus a whole picture of your browsing habits can be painted. 

Your VPN will stop this happening. 

  • Out And About 

Your VPN will continue to work for you when you’re on the move. Anywhere you go, your connection must be made between you and your VPN server. 

You will have heard that connecting to WiFi in public places can be a security risk. 

Well with a VPN this risk is greatly reduced. You can now connect to public Wi-Fi safe in the knowledge that your connection is protected by the encryption between your computer and the VPN server. 

VPNs are used around the world to counter government censorship and gain access to otherwise illicit websites. VPNs can do this because of the location of their server. Say for instance your VPN server is located in Switzerland, you you want to view a website that is banned in your country. No problem. You computer makes the request from the VPN. The VPN makes the request from the URL and then passes it securely to your PC.

  • What A VPN Cannot Do 

It is important to consider that there are things that a VPN cannot do. 

It cannot render you impervious to prosecution for illegal activity. Your data has become a lot more difficult to read, but if local law enforcement have reason to believe that you are breaking the law, there are ways to counter anonymity. 

A VPN cannot stop you losing your data to phishing websites. You are still responsible for your safety online. A VPN cannot protect you from many online scams that target your data so you need to stay aware.
