What is a VPN and How Does a VPN Work?

In today’s digital age, online privacy and security have become paramount. One tool that can help protect your online activities is a Virtual Private Network (VPN). In this article, we will delve into what VPNs are and how they work. Additionally, we will discuss the top three VPN options available in the market.

What is a VPN?

A VPN stands for Virtual Private Network. It functions as a secret tunnel on the internet that keeps your online activities private. When you use a VPN, it takes your internet data and encrypts it, making it difficult for others to understand what you are doing. This means that your Internet Service Provider (ISP) and even the government will not be able to track your online activities.

To better understand this, imagine sending a postcard through the mail. Anyone who handles the postcard can see what is written on it. However, if you put the postcard in a locked box, only you and the person with the key can see the message. A VPN acts as that locked box, ensuring that only you can access your internet data.

Moreover, a VPN also masks your actual location. For example, if you are in New York and connect to a VPN server in New Jersey, websites will see your browsing activity as originating from New Jersey. This enhances your online privacy. Furthermore, a VPN can help you bypass geographic restrictions, allowing you to access websites or watch videos that may be blocked or unavailable in your home country.

However, it is important to note that while a VPN provides privacy and security, it is essential to comply with local laws in your online activities.

How a VPN Works?

To understand how a VPN works, let’s visualize it as a connection between your device and the internet. Without a VPN, your device is directly connected to your ISP, meaning your ISP has access to your online activities. When you use a VPN, your device connects to the internet through a VPN server, creating a protective barrier between your device and the ISP. This way, your IP address, which identifies your device’s network, is hidden. Instead, the IP address associated with the VPN client is used.

To check this, you can use a service like “What is my IP address,” and it will show you the location of the VPN server rather than your actual location.

Top VPN Choices

Now that we understand what a VPN does, let’s explore the top three VPN options available on the market:

  1. ExpressVPN: This VPN is highly recommended for its user-friendly interface, reliability, and top security and performance. ExpressVPN provides a seamless experience with an intuitive on/off button, numerous servers in various countries, and consistent speeds. It ensures that your online activities remain private and protected while being incredibly easy to use.
  2. NordVPN: A close competitor to ExpressVPN, NordVPN also offers excellent performance and security. It provides additional features, making it a well-rounded VPN option. While slightly more feature-rich than ExpressVPN, NordVPN is still user-friendly and reliable.
  3. Surfshark: For those on a budget, Surfshark offers the best choice without compromising on security features. While it may be slightly slower compared to the previous two options due to encryption processes, Surfshark still provides commendable speed in its own right. It proves to be a cost-effective VPN option while maintaining robust security measures.
