Site to Site VPNs primarily serve corporations that may have offices located in different locations. Site to Site VPN’s main feature is its ability to connect networks belonging to one office in a particular location to another network belonging to an office in another location.
If those offices are of the same company, the site-to-site VPN becomes an Intranet based VPN. If offices belong to different companies, the site-to-site VPN becomes an extranet VPN service. Site-to-site VPNs can establish digital communication lines between networks that can be present on different continents.
The benefit of using the site-to-site VPN is the privacy and security of any communications or activities that may happen between two given networks belonging to the same or different companies. And since site-to-site VPNs require authentication before communication lines can be established, they are perfectly suited to a situation where an employee wants to access sensitive files and other types of content over the internet from a remote office and/or collaborate with another company over the internet.
