A site-to-site VPN (virtual private network) is a connection set up between multiple networks. This include a corporate network in which multiple offices work with each other or a branch office network that includes a central office and multiple branch locations.
You can use site-to-site VPNs to prioritize private and protected traffic, especially if your organization spreads across geographical locations. Oftentimes, these locations have to access resources on a primary network, which could include multiple servers that facilitate email or data. A site-to-site VPN can provide full access to all locations to the resources, as if they are housed within the physical location.
