VPN Explained: How Does a VPN Work?

Introduction

As internet privacy and security become increasingly important, Virtual Private Networks (VPNs) are gaining wider recognition as one of the most effective ways to safeguard your data online. This article dives into the world of VPNs and explains how they work.

What is a VPN?

A VPN creates an encrypted connection between your device and the VPN server to enhance online privacy and protect sensitive information. It establishes a secure and private connection by routing all your traffic through the VPN server. This ensures that your online activity is hidden from third parties such as government agencies, hackers, or internet service providers.

How Does a VPN Work?

A VPN encrypts your internet traffic ensuring that your data is secure and unreadable by anyone outside your connection. Once you initiate the VPN connection, the VPN client on your device encrypts your connection request and sends it to the VPN server. Your online activities, such as browsing, downloading, and uploading, are then routed through the VPN server.

The VPN server acts as an intermediary between your device and the internet, making it difficult for others to track your online activity. This is because the VPN server assigns you a new IP address, which can conceal your actual location from prying eyes. With an encrypted tunnel between your device and the VPN server, your ISP cannot track or monitor your online activity.

Why Use VPN?

VPNs are used to bypass geographical restrictions, censorship, and network firewalls. With a VPN, you can unlock content that may be restricted in your country like Netflix, Hulu, Amazon Prime Video, or BBC iPlayer. It allows you to access websites and content that may be blocked by your ISP or government.

Moreover, VPNs have a kill switch, which automatically disconnects your device from the internet if your VPN connection drops. This is especially useful if you’re torrenting or using other online activities that require maximum security.

Top Three Recommended VPNs

While there are numerous VPN providers in the market, some stand out with their features and performance. The top three VPNs recommended are ExpressVPN, NordVPN, and Surfshark.

ExpressVPN is an excellent option for those who value both speed and security. With servers in 94 countries, it provides excellent speeds and performance. On the other hand, NordVPN offers high-level security with AES 256-bit encryption and a strict no-logs policy. Lastly, Surfshark offers unlimited simultaneous connections and a budget-friendly plan without sacrificing speed or performance.
