What is the primary purpose of a VPN?

The primary purpose of a VPN (Virtual Private Network) is to provide a secure tunnel for data transmission. A VPN establishes a private and encrypted connection over a public network, allowing users to safely transmit sensitive data and maintain privacy while online. By encrypting the data before it travels across the internet, a VPN protects it from potential eavesdroppers and cyber threats, ensuring that personal information, corporate data, or any other transmitted content remains confidential.

The other options do not accurately represent the main function of a VPN. While some people may use a VPN to bypass certain geographical restrictions or firewall regulations, this is not its primary intent. Additionally, a VPN does not specifically encrypt emails or text messages; rather, it secures internet connections overall, affecting all data transmitted over the network. Finally, enhancing internet speed is not a purpose of a VPN. In fact, using a VPN can sometimes lead to slower internet speeds due to the additional processes of encryption and routing through VPN servers.
