How Virtual Private Networks Work

Protecting your digital privacy has never been more important. In today’s online world, almost everything you do—from shopping to banking to working—is done online. A Virtual Private Network is the answer. Before we get into the technical jargon, let’s break it down so that anyone can understand.

Imagine that you are writing a card in a café. Anyone can read the postcard. Imagine slipping the postcard into an envelope with a secure seal before mailing. A VPN protects your data and keeps it secure while it travels through the Internet.

VPN—What Is It and Why Do You Need One

A Virtual Private Network (VPN) is a service that encrypts and hides the internet connection. It creates a “tunnel,” which is a secure connection between your device and the internet. This prevents others from spying on your online activity, even when using Wi-Fi networks.

This is a true story. Jane, a graphic designer, works from airports and cafes. She noticed that her bank account had been charged in an unauthorized manner one day. It turned out that someone had intercepted Jane’s data while using a public WiFi. Jane began using a VPN and has never had the problem again.

By using a Virtual Private Network, your identity online, personal data, and location are hidden, giving you peace of mind wherever you are online.

VPNs come in different forms, each with its unique features.

A real-world scenario of how VPN works with WiFi

Have you ever connected to free Wi-Fi at an airport or coffee shop? It’s convenient, isn’t it? It’s not safe—hackers can easily intercept data.

A VPN is the best solution. You can use a VPN when you are on Wi-Fi.

It encrypts the connection so that no one can access your data.
Your real IP address is hidden.
It is nearly impossible to track your internet traffic because it goes through a secure server.

If someone intercepts data from your computer, they will only see gibberish.
