What is a VPN and how does it enhance network security?

A VPN, or Virtual Private Network, is a technology that allows users to create a secure connection over a public network, such as the internet. It can enhance network security by encrypting data transmitted between the user's device and the destination network. This encryption ensures that sensitive information, such as login credentials or financial data, is protected against interception and unauthorized access by cybercriminals. By routing data through a VPN server, it also masks the user's IP address, providing anonymity and preventing potential tracking. Moreover, VPNs enable users to bypass geographical restrictions, accessing content and services that may otherwise be unavailable in their location. Overall, VPNs play a crucial role in securing network communications, safeguarding sensitive information, and preserving online privacy.
