What is a Site-to-Site VPN?
A site-to-site VPN allows offices in multiple locations to establish secure connections with each other over a public network such as the internet. Site-to-site VPN extends the company’s network, making computer resources from one location available to employees at other locations.
What type of business uses a Site-to-Site VPN?
A site-to-site VPN is beneficial to a growing business with several branch offices around the nation or across the world. For example, a London-based consultancy firm opens branch offices in Birmingham, Paris, Rome and New York with 10 to 20 employees at each location who need to access email, a shared file server, and other network resources at the central office. The network demands of 10 to 20 employees at each location would be relatively small to justify the cost of a dedicated, leased internet line at each site. A site-to-site VPN would link all of the branch offices together with only the cost of a local internet connection.
