A VPN, or Virtual Private Network, is a technology that creates a secure connection over the internet, allowing users to send and receive data as if their devices were directly connected to a private network. This is particularly useful for protecting sensitive information and maintaining privacy while browsing online. By encrypting your internet traffic, a VPN helps shield your online activities from prying eyes, such as hackers and government surveillance. It also allows users to access geo-restricted content by masking their IP address, making it appear as though they are browsing from a different location.
