What does a virtual private network (VPN) do?

A virtual private network (VPN) plays a crucial role in securing online communications and maintaining user privacy. Its primary function is to encrypt data transmitted over the internet, which transforms the information into a code that is unreadable to anyone who might intercept it. This encryption safeguards sensitive data from cyber threats, providing a secure tunnel for internet traffic. Additionally, a VPN masks the user's IP address, enhancing privacy and anonymity while browsing the web.

While some misconceptions might exist about VPNs, the option discussing remote access reflects only one of the uses but does not encapsulate the full function of a VPN. Their capabilities extend far beyond just facilitating access to local networks, making the encryption and privacy features a more comprehensive answer. Overall, the primary advantage of using a VPN hinges on its ability to provide a secure and private browsing experience, distinguishing it from other network solutions.
