What is a VPN primarily used for?

A VPN, or Virtual Private Network, is primarily used to provide secure remote access to a network. This technology creates a secure and encrypted connection over a less secure network, such as the internet. By establishing a VPN, users can connect to their organization's network from remote locations while maintaining confidentiality and security of their data.

The encryption used in VPNs protects sensitive information from potential interception and unauthorized access. This is particularly valuable for employees who need to access corporate resources securely while working from home, on the road, or in public places. The VPN also helps circumvent geographic restrictions and allows users to maintain privacy by masking their IP addresses.

While enhancing network speed, filtering network traffic, and allocating bandwidth may be relevant to network management and performance, these are not the primary purposes of a VPN. Instead, the core function of a VPN focuses on security and privacy, making it essential for anyone needing secure access to their network remotely.
