VPNs Explained: How Do They Work?

The internet’s threat to privacy can no longer be ignored. Gone are the days when VPNs were dismissed as only needed by privacy nuts, conspiracy theorists, and users with legally iffy browsing habits. Now, with cybercrime on a rapid rise, many people are starting to care about VPNs.

VPNs (short for Virtual Private Networks) give you added security and privacy when connected to the internet. As outlined in this PureVPN Review 2020, VPNs come with powerful encryption and a strict privacy policy ensuring everything you do online remains private.

In this article, we’ll take a closer look at how a VPN works and how using one can protect your sensitive data from any prying eyes.

Increased usage of VPNs

Over the last few years, the number of people using a VPN has increased drastically. So much so, that according to Statista, the total number of VPN users grew by a whopping 165% from 2017 to 2018.

This is a clear indication that VPNs are becoming ever-more popular around the world, which shouldn’t come as a surprise considering the fact that cybercriminals are always coming up with new ways to get their hands on personal data.

In the years to come, cybercrime will only become more of an issue, which means that internet users will need to take the necessary precautions to avoid becoming victims.

A VPN can undoubtedly make a huge difference when it comes to the protection of your personal information. In the next section, we’ll take a closer look at how a VPN works to stop third parties from spying on your online communications.

How a VPN works

You probably already know what a VPN is and might even be using one already. So, we’ll spare you the details when it comes to the basics. But, continue reading if you’d like to find out more about how they work.

Primarily, a VPN works to prevent anyone from intercepting and reading your data. It does so by creating an encrypted tunnel through which your traffic is routed before being allowed to join the public Internet. While your ISP can see you are using a VPN, they are unable to decipher the contents of your traffic.

Even while on a public Wi-Fi network, a VPN can ensure no unauthorized access to your data occurs. These hotspots are prime targets for hackers, snoopers, and other malicious individuals looking to prey on unsuspecting users.

By masking your IP and spoofing your location, VPNs also give you the ability to bypass censorship and geo-restrictions.

Final Word

A VPN can help you reclaim your online privacy and browse anonymously. Also, your data will be protected giving you peace of mind when shopping or even gaming online. With a VPN, you can also obliterate digital geographical borders and access virtually any content on the web.
