"VPN" stands for Virtual Private Network in network security. It is a technology that creates a secure and encrypted connection over a less secure network, like the Internet. VPNs are primarily used for protecting privacy and enhancing security while accessing untrusted networks. By routing internet traffic through a server, it masks a user's IP address, ensuring anonymity and data safety. This is particularly important for individuals who want to safeguard sensitive information, especially when using public Wi-Fi. Businesses also utilize VPNs to enable secure remote access for employees, underlining their significance in maintaining network security.
