Techopedia explains Site-to-Site VPN
Site-to-site VPN typically creates a direct, unshared and secure connection between two end points. Site-to-site VPN can be intranet based or extranet based. Intranet-based site-to-site VPN is created between an organization's propriety networks, while extranet-based site-to-site VPN is used for connecting with external partner networks or an intranet.
The connection in a site-to-site VPN is generally enabled through a VPN gateway device.
