The most important benefit of Site-to-Site VPN Connection is security, as IPsec protocols ensure that all traffic passing through the VPN tunnel is encrypted.
2. Unlike a remote access VPN, which requires that each employee system run VPN client software, a site-to-site VPN only requires a VPN gateway at each location. This makes it simple to add a new site or office branch to the network, as well as relocate a remote office or site.
3. Site-to-Site VPN Connections are simple to scale. New users, sites, offices, or partners can be up and running in minutes. You also won't have to add individual devices to the existing network one by one. Deploying gateways allows you to add a new network to an existing one, making expansion simpler.
4. In the event of a disaster or emergency, you do not have to shut down the entire operation at once. By using a site-to-site VPN Connection, you can grant or deny access to LANs as needed. As a result, disconnecting the affected LAN and replacing it with a new one can ensure business continuity.
