A VPN, or Virtual Private Network, is a technology that creates a secure and encrypted connection between a user's device and the internet. By routing the user's internet traffic through an encrypted tunnel, a VPN protects their online privacy and security by preventing third-party entities from monitoring or intercepting their online activities. VPNs are commonly used to access restricted content, bypass internet censorship, and protect sensitive data while using public Wi-Fi. With a wide range of VPN providers available, users can choose from various features such as server locations, speed, and additional security measures to find the best VPN for their needs.
