A VPN works like a middleman between you and the Internet. Instead of directly communicating with a website, you would go through a VPN server, mainly to keep your online activities private.

Let’s say, for example, that you want to transfer money from your bank account to a family member. To do that, you would need to go to the bank’s website (www[.]yourbank[.]com) and type in your username and password.

Without a VPN, your login credentials and bank account information are exposed to whoever is watching your network. Note that we are not only talking about hackers. Your Internet service provider (ISP), the government, and network administrators in your office can see your online activities. 

With the right tools, they could extract your data since it is exposed and unprotected. The image below illustrates how people with enough tools and technical expertise can see your data (within the data packets).

In contrast, a VPN creates a tunnel where your data packets pass through, keeping them out of sight from other entities. By using a VPN, your data becomes encrypted or converted into a code that no one but the destination (your bank’s website in our example) can interpret.

What Is a VPN?

A VPN is a piece of software that encrypts the data your device sends to the Internet. It turns your data into jumbled code so even when other people are watching, all they can see is the code. They won’t be able to make sense of it since the data is encrypted.

Most VPN providers use the latest encryption technology and standards, making it impossible for hackers to decrypt your data.

What Data Can a VPN Hide?

Now that you know how a VPN works, you understand why it is one of the primary tools people use for privacy protection. A recent study shows that 49% of VPN users employ the service for security reasons, 40% for privacy, and 31% for using public Wi-Fi networks.

But what, specifically, can a VPN hide? Below are three crucial things that a VPN protects.

Visited Websites and Applications

When you visit a website, your device sends data packets to its server. These data packets are encrypted by the VPN so they are hidden from other people. Therefore, your browsing history is safe from prying eyes. You can access your bank account or medical records online without worrying about your ISP, browser, or hackers tracking your every move.

IP Address

A VPN can hide the IP address of any device you’re using. The IP address serves as its ID on the Internet, revealing many things about you. Using a VPN practically makes you anonymous online.

Device Type and Location

Since a VPN hides your IP address, it also conceals your location and the type of device you’re using. This functionality helps you access websites that are otherwise unavailable in your current location.

Your browsing history, IP address, and location are private data that should stay protected. When such information falls into the wrong hands, you could suffer from a significant problem. Your identity could be stolen and used maliciously. Cybercriminals could also hack into your bank accounts and steal your hard-earned money.
But encryption lies at the heart of how a VPN works. It is the primary benefit users gain. By encrypting your data on the Internet, a VPN camouflages your identity, activities, and information.
