Which of the following describes a significant advantage of using a VPN?

The significant advantage of using a Virtual Private Network (VPN) is enhanced security and privacy over internet connections. A VPN creates a secure tunnel between the user's device and the VPN server, encrypting the data transmitted through it. This encryption makes it significantly harder for unauthorized parties, such as hackers or government surveillance, to intercept and access sensitive information.

Additionally, a VPN masks the user's IP address, providing anonymity while browsing the internet. This is particularly valuable when using public Wi-Fi networks, where security risks are amplified. By protecting data from potential threats and safeguarding personal information, a VPN not only enhances security but also fosters privacy, keeping the user’s online activities confidential from third parties.

While lower operational costs, improved data transmission speed, and increased device compatibility are worthwhile considerations, they do not capture the primary purpose and critical advantage of a VPN, which is to secure data and protect privacy in various online environments.
