A VPN or Virtual Private Network is a piece of software designed to protect your privacy on the Internet and make life hard for hackers by anonymizing your traffic and location.

It is a secure, encrypted connection between two networks or between a user and a network. A VPN connection allows you to securely access applications, websites, and entertainment platforms from anywhere in the world. In addition, the connection itself is encrypted, so you cannot see what data you are transmitting, downloading, and sending. Encryption is the transformation of readable text into unreadable code. There are three main types of encryption: hashing, symmetric cryptography, and asymmetric cryptography. Each type has its strengths and weaknesses, but each type of encryption effectively distorts your data so that no one can take advantage of it.

Currently, there are many VPN service providers. They come in different forms and use different methods to improve the safety of using the Internet, and they differ in price.

VPN encrypts all data sent over the Internet

When you're connected to a VPN server, all your internet traffic is encrypted. This means no one can see what you are doing online, not even your ISP, nor can they limit your speed, which is often the case if you are doing Internet-intensive work. Encryption prevents hackers from seeing sensitive information you enter on websites, such as passwords. This is especially important if you are on a public Wi-Fi network, as cybercriminals can easily monitor your connection on a public network. But a VPN ensures that even if someone steals your data, they won't be able to decrypt it or even understand it.

VPN also hides your IP address

Websites and services, such as Netflix, use your IP address to determine your location.

Since they can no longer see your real IP address, they cannot see your location. This is of utmost importance if you want to torrent or bypass censorship. This means you can access any show, movie, or game in the world and browse with complete freedom.

Some VPNs block websites, ads, and trackers 

Malicious websites may place software and trackers on your device without your knowledge. VPNs with built-in protection help prevent infections by blocking those sites before they can do harm.
