This form of virtual private network isn’t based in the world of personal computers or smart devices. Instead, site-to-site VPN connects two or more corporate networks. For instance, a link from the main headquarters to the network of a branch office. It can also be used for companies with multiple offices located in areas across the globe. Instituting VPN leads to ongoing access without the need to continually log out and log back in with credentials. Furthermore, the business can create a series of IP subnets that are only viewable by those who work for the organization. Thus, a single network entity is created.
