The term used to describe a VPN implementation where a company connects to its supplier is "Extranet." This type of network allows specific external users, such as suppliers or partners, to access certain resources within a company's internal network. Extranets are designed to enhance collaboration and secure communication between businesses by enabling access to shared applications, data, and services while maintaining the privacy of the company's internal network.

In contrast, an intranet is a private network accessible only to an organization’s members, employees, or others with authorization. Remote-access VPNs enable individual users to connect securely to a company's network from a remote location, while site-to-site VPNs create a secure tunnel between two networks, often used to connect branch offices to a main office. These other types of network configurations serve different purposes and do not focus on the specific connection between a company and its suppliers.
