A site-to-site VPN secures the connection between branches and remote workers with the main company server.
A virtual private network, or VPN, is a secured remote server used to relay the entirety of one’s internet connection through that server. Similarly to how a private VPN masks the person’s IP address, a site-to-site VPN, or S2S VPN, also provides a specific IP address. Then, separate on-site servers in different business branches recognize and accept these IP addresses.
That said, you might see this topology where all the branch servers must connect to the main branch through a direct hierarchy as slightly obsolete. With many companies moving to cloud-based servers, it’s easier for the whole company to share the same cloud server. However, site-to-site VPNs still have benefits.
In this article, I’ll discuss site-to-site VPNs, their benefits, and some of their limitations. Later, I’ll touch on the different types of VPNs and tools you can use to make the most of them.
