What Is A VPN And How Does It Work? 2025

When I think about VPN, I think about the following story: John sat at Starbucks, sipping his latte while checking his bank account using the free Wi-Fi. Unbeknownst to him, a hacker was lurking on the same network, intercepting his data. Moments later, John’s login details were stolen, and his savings vanished.

Had he used a VPN, his connection would have been encrypted, protecting his sensitive information from prying eyes. A simple VPN could have saved him from a costly mistake.

What Is A VPN?

A VPN (Virtual Private Network) protects your online activity by creating a secure, private connection between your device and the internet. It hides your IP address and encrypts your data, making it appear as if you’re browsing from a different location. This keeps your information safe from hackers, advertisers, and anyone else trying to track what you do online.

How Does A VPN Work

A VPN creates a secure “tunnel” between your device and the internet. As soon as you connect, it encrypts your data—turning it into a code that only your device and the VPN server can understand. The VPN server then takes over, sending your request to the website or service you want to access. Since the server sits in a different location, it masks your real IP address and makes it look like you’re browsing from somewhere else. This way, you stay private online, block hackers from snooping, and unlock content that’s restricted in your region.

What are the 4 major features of a VPN?

01. Your Personal Information Will Be Save

When using A VPN Service, your personal information, like IP address, login details, browsing history, and cookies, are encrypted and not accessible by third parties. So your information is completely safe.

02. No More Firewall – Watch Netflix From Any Country In The World

When using a VPN service, you can access the internet through a VPN server from any place in the world. For instance, if you are in China and you have no access to YouTube, you can use a VPN server in the United States, and in that way, YouTube thinks you are accessing them from the United States.

This can also be handy when your favorite sitcom is not available in your country but is available in another country. Just select that country using your VPN service, and you can watch your favorite sitcom again.

03. It Fixes Unsecured WiFi

When you have access to Free WiFi in any open area, oftentimes that network is unsecured, which makes it easier for cybercriminals to steal your information and get access to things they should not get access to.

When you use a VPN service, using Free Wifi makes it still very hard for cybercriminals to steal your information.

04. Overcome Wi-Fi restriction

In a lot of schools, Wi-Fi has some restrictions. In some cases, you can only enter the school’s website and portal. Using a VPN, you can still make use of the whole internet.

So you bypass the restriction using a VPN.
