What Does A VPN Do: All about Virtual Private Networks



Virtual Private Networks (VPN) aren’t a common knowledge among many internet users, and some of those who are actually aware of its existence don’t even bother getting one. Having a VPN is as important as having an internet connection – and if you truly want to browse the web completely safe, getting one would be one of the best decisions of your life. Below, we will answer a frequently asked question among internet users: what does a VPN do?


What Is A VPN?


A Virtual Private Network (VPN) is a technology that creates a secure connection over a public network such as the internet. Using a VPN provides the users a secure private connection even if they’re not in the same local area network (LAN). It also connects multiple computers to gain access to resources even if they are in remote areas.

So what does a VPN do to protect your privacy? VPNs ensure your privacy by hiding all your internet activities from your internet service provider and lets you evade censorship by your school, work, internet service provider, or the government – anything that prohibits you from visiting websites. It also bypasses geo-restrictions and lets you use public Wi-Fi hotspots securely.

Using a VPN has many advantages in terms of privacy and resource access. This is why it is important to know the answer to ‘what does a VPN do?’ since many VPN services are out in the market today which promises to provide you with safe and secure internet experience.



How Does a VPN Work?


When using a VPN, all the data travels between your computer and the VPN server – which means your internet service provider is unable to see it. All your data goes through an encrypted connection called a ‘VPN tunnel’. Anyone can intercept your data, but they won’t be able to read it because it’s encrypted.

A VPN masks your IP address by using its own including the country you are located in. This means that if the VPN server you are using is located in a different country from yours, you will appear to be accessing the internet in that country. If anyone tries to monitor your activity, they will only trace it back to the VPN server.

Your internet service provider may not know what you’re up to, but your VPN server does. Your real IP address is hidden from other websites, and unless your VPN server hands your usage to third parties, your usage will remain hidden. It’s better to research ahead on servers that take their user’s privacy seriously.

One factor to consider, though, is the processing power required to encrypt and decrypt data which could slow down your internet speed. The VPN server’s location is also another factor, because the farther the distance that the data has to travel, the longer it takes for you to receive it. So another tip on choosing a VPN server is to pick one located nearest to yours.

Why Use A VPN?


            Now that your answer to the question ‘what does a VPN do?’ has been answered, it is time to know why you should use a VPN if you still aren’t convinced to use one.

  1. It ensures your security. Whether you’re a businessman who wants to keep your data safe from intruders, or just simply an employee who wants to protect your online accounts, a VPN encrypts your data so that anyone who tries to intercept it won’t be able to read it.


Whenever you connect to an untrusted network, such as a coffee shop’s Wi-Fi, you’re putting your data in a potential danger. This means that checking your email, typing in your bank account details, or logging in to your social media accounts could put you at risk for hacking and identity theft. Using a VPN secures all the information that you enter from your devices to keep it away from prying eyes.


  1. It enables you to access resources anywhere. Some users might think twice about why they should use a VPN. VPNs are extremely beneficial to students, employers, and their employees. A VPN connects remote computers together through the internet, providing a reliable way of sharing information and resources even when the computers are extremely far from each other.


Using a VPN helps you become more productive because you can take your work with you wherever you go. Whether you’re traveling to another country or simply staying at home, you can access resources anywhere you are at any time you want.


  1. It helps you save money and time. If you’re employed and your office is too far from your home, using a VPN can actually help you save money and time from traveling to work every day. The time you spend on traveling can be allocated to other important activities – another productivity tip.


Using VPN for work is very convenient for you because you can communicate with your colleagues and do your tasks at the comfort of your own home. Many businesses have been using VPNs in their virtual workplaces because of its convenience, practicality, and security advantages.


  1. It lets you download online safely. Many people use a VPN when downloading from BitTorrent to protect themselves from charges against illegal downloading. Some users also use a VPN even if they are legally downloading, to hide their usage and to keep hackers from snooping in on their downloaded files.

While using a VPN may hide your usage, be sure that the service you’re using is reliable. Some VPN services will keep logs off all your activity, then sell it to those who will ask for it. Others will log in your usage and make it available to anyone else, so it’s best to do your research on which VPN services take their user’s privacy seriously. Always read their privacy policy first, and make sure that they don’t keep logs.


  1. It bypasses geo-restrictions. You’ve most likely experienced the agony of wanting to watch the coverage of your favorite football game or foreign TV show in real time, then having to watch the replay or another country’s version of the show because it is location-restricted. This is one of the reasons why many users resort to using a VPN.


The VPN bypasses country restrictions which allows you to watch TV shows as they air or download apps which are otherwise unavailable in your location. To do this, the VPN bluffs your IP address – including the apps on your computer and phone – which changes your location. This makes downloading and streaming more convenient for users around the globe.
