A Virtual Private Network (VPN) is primarily designed to provide security and privacy for users' online activities. One of the key features of a VPN is its ability to encrypt data transmitted between the user's device and the VPN server. This encryption ensures that any data sent or received—such as browsing activity, personal information, or sensitive communications—is protected from interception by unauthorized parties.

This security mechanism is essential for maintaining privacy, especially when using public Wi-Fi networks or engaging in activities that require a higher degree of confidentiality. While a VPN can sometimes improve speed for streaming due to reduced throttling from internet service providers or local governmental restrictions, its primary function is to safeguard data through encryption.

Additionally, while a VPN can enhance privacy and make it more difficult to trace online activities back to an individual, it does not guarantee complete anonymity, as there may still be leaks or data traceability through other means. Moreover, while a VPN might allow access to geo-restricted content, such as online games, this is not its primary function. Thus, the correct answer highlights the VPN's vital role in encrypting data to protect browsing activities effectively.
