The purpose of a VPN (Virtual Private Network) in information technology is to create a secure, encrypted connection over a less secure network, such as the internet. By establishing a VPN, users can protect their online activities and sensitive data from prying eyes, including hackers and surveillance. It allows remote users to access a private network securely, often used by businesses to enable employees to connect to company resources safely. Additionally, VPNs can bypass geographic restrictions, enhancing access to content and providing users with greater privacy and anonymity online.
