A virtual private network (VPN) provides a secure transmission method for communication by creating an encrypted tunnel between the user's device and the internet or a remote network. This encryption protects data from eavesdropping and unauthorized access, ensuring that sensitive information remains confidential while being transmitted over potentially insecure networks, such as public Wi-Fi.

Using a VPN effectively masks the user's IP address, making the online activities more private and secure. This functionality is especially crucial for businesses and individuals who need to protect data integrity and confidentiality during communication, particularly when accessing sensitive information or connecting to company resources remotely.

Other choices, such as methods for non-secure communication or providing public access to private files, do not adequately represent the secure nature of a VPN. Enhancing network speed is also not a primary function of a VPN; its main focus is on securing the data transmission. Consequently, the most accurate understanding of what a VPN offers is its capability for secure communication.
