What is the primary function of Client-to-Site (Remote Access) VPNs?

The primary function of Client-to-Site (Remote Access) VPNs is to allow secure connections for individual hosts to a company network. This type of VPN enables remote users, such as employees working from home or traveling, to securely access the company's network resources and services as if they were directly connected to it. By establishing an encrypted tunnel between the user's device and the company's network, Client-to-Site VPNs protect sensitive data from interception and ensure that users can access internal applications and files securely over the internet.

This functionality is essential for organizations that support remote work, providing flexibility while maintaining security. While other options touch on aspects of networking, they do not specifically pertain to individual users accessing a company's resources securely from remote locations, which is the unique purpose of Client-to-Site VPNs.
