A VPN client is a software application that allows users to connect to a Virtual Private Network (VPN). This connection encrypts the user's internet traffic, providing privacy and security while browsing online. By using a VPN client, individuals can access restricted content and protect their data from potential threats. Typically, a VPN client is available for various devices, including computers, smartphones, and tablets. Once installed, users can select a server location and establish a secure connection, making it appear as if they are browsing from that location. This helps maintain anonymity and bypass geographical restrictions.
