The primary function of a virtual private network (VPN) is to create a secure connection over a public network, allowing users to transmit data safely. By encrypting internet traffic, a VPN ensures that sensitive information remains private and protected from potential eavesdroppers or hackers. Additionally, VPNs can mask users' IP addresses, enabling anonymous browsing and improved online privacy. This technology is especially beneficial for remote workers accessing company resources or individuals seeking to bypass geographical content restrictions, ultimately enhancing cybersecurity and privacy.
