What is a VPN?

A virtual private network (VPN) gives you online privacy and anonymity by creating a private network over a public internet connection. VPNs mask your IP address (Internet Protocol) so that your online actions are practically incomprehensible. Most importantly, free VPN services establish secure and encrypted connections to provide more data protection than even a secured Wi-Fi hotspot.

Why do you need a VPN service?

When surfing the Internet or making transactions on an unsecured Wi-Fi network, you can disclose your private information and browsing habits. For this reason, a virtual private network, better known as VPN, should be a must for anyone concerned about their online security and privacy.

Think of all the times you were traveling, reading emails while standing in line at the cafe, or checking your bank account while waiting in the doctor's office. Unless you are logged into a private Wi-Fi network that requires a password, data that is transmitted during your online session can be intercepted by strangers who use the same network.

The encryption and anonymity that a VPN offers protects your online activities: send emails, shop online or pay bills. VPNs also help keep Internet surfing anonymous.

How a VPN protects your IP address and your privacy

VPNs essentially create a data tunnel between your local network and an exit node in another location, which can be thousands of kilometers away, making it look like you are in a different location. This advantage allows online freedom or access to your favorite apps and websites on the go.

Here you can see more precisely how a virtual private network works. VPNs use encryption to encrypt data when it is sent over a Wi-Fi network. The data cannot be read due to the encryption. Data security is particularly important when you use a public Wi-Fi network because it prevents other people on the network from eavesdropping on your Internet activity.

There is another side to privacy. Without a VPN, your internet service provider can know your entire browsing history. Your search history is hidden with a VPN. This is because your web activity is linked to the IP address of the VPN server, not yours. A VPN service provider may have servers around the world. This means that your search activity appears to come from any of them. Note that search engines also track your search history, but link this information to an IP address that is not yours. Here, too, your VPN keeps your online activities private.
