A site-to-site VPN is an encrypted connection that links two or more networks so they can communicate securely across an untrusted transit network. It matters because organizations often need to extend internal connectivity between offices, data centers, or cloud environments without exposing traffic openly.
What is Site-to-Site VPN?
Site-to-site VPNs commonly use IPsec or similar technologies to create protected tunnels between network gateways. They are foundational in hybrid connectivity, branch networking, and secure partner or cloud interconnection.
What Site-to-Site VPN Commonly Supports

Site-to-Site VPN vs. Remote Access VPN
A site-to-site VPN connects networks to each other. A remote access VPN connects an individual user or device into a network.
