What Is a Virtual Private Network (VPN) and How Does It Work?

What Is a Virtual Private Network (VPN)?

In an age where digital privacy is more valuable than ever, the term “VPN” comes up often—but what exactly is a Virtual Private Network? A VPN, or Virtual Private Network, is a secure tunnel between your device and the internet. It hides your IP address, encrypts your data, and keeps your online activities private—even on public Wi-Fi.

Why Do People Use VPNs?

People use VPNs for various reasons:

To protect their personal data from hackers on public networks
To access region-locked content like Netflix, Hulu, or BBC iPlayer
To avoid being tracked by websites, advertisers, or even their own internet service provider (ISP)
To bypass censorship in countries with restricted internet access

How Does a VPN Work?

When you connect to a VPN, it reroutes your internet traffic through an encrypted server in a different location. This process:

Hides your real IP address
Encrypts your internet traffic, making it unreadable to anyone trying to snoop
Allows you to appear as if you’re browsing from another country

For example, if you’re in the Philippines and connect to a VPN server in the US, websites will think you’re in the US. This is how users access streaming content, social media platforms, and websites that may otherwise be blocked or restricted.

Is a VPN Legal?
