How does a VPN enhance security?

A VPN (Virtual Private Network) enhances security primarily by creating a secure, encrypted connection over the internet. This means that when data is transmitted over the VPN, it is encrypted, making it difficult for unauthorized parties to intercept and read the information. This is particularly important when connecting to public Wi-Fi networks, where data can be exposed to various security threats.

The encryption provided by a VPN ensures confidentiality and integrity of the data being sent and received. This technology also conceals the user's IP address, further protecting their identity and location from potential attackers or intrusive entities. By using a VPN, individuals and organizations can safeguard sensitive information, maintain privacy, and reduce the risk of data breaches.

While other options may describe features or functions related to internet use, they do not directly address the core security enhancement that a VPN provides, which is the establishment of a safe and encrypted communication channel.
