What is a VPN used for?

A VPN, or Virtual Private Network, is specifically designed to create a secure and encrypted connection over potentially untrustworthy networks, such as public Wi-Fi. This allows users to send and receive data as if they were directly connected to a private network, ensuring confidentiality and integrity. By encrypting the data, a VPN protects users from various security threats, such as eavesdropping, data interception, and privacy breaches, making it a vital tool for individuals and organizations that prioritize data security.

In contrast, while a VPN may indirectly influence internet speed depending on various factors—like the distance to the VPN server or server load—its primary function is not to speed up connections. The enhancement of video streaming quality may occur as a side benefit due to reduced buffering from a more stable connection, but again, this is not the main purpose of a VPN. Additionally, filtering unwanted content is not a function of a VPN; instead, content filtering typically involves other tools such as web filters or parental control software. The key focus of a VPN remains on secure, encrypted communication.
