Mobile broadband, cable, and DSL providers have made notable increases in market penetration over the past decade, making access to high-bandwidth Internet connectivity almost ubiquitous. The increased adoption has also made these types of Internet connectivity less costly than private leased line alternatives. By combining VPN technology with common Internet access, organizations are able to extend the speed and reach of their network while also reducing costs. VPNs are generally divided into one of two high-level categories: site-to-site (also known as gateway-to-gateway) or remote access (also known as client-to-gateway or dialup). While the fundamental concept of providing an encrypted tunnel between two networked nodes remains constant in both categories, the implementation and technologies used to deliver the solution differ substantially. Fortinet VPN solutions offer customers a broad range of options for establishing VPNs in both major categories by supporting IPsec, SSL-TLS, and L2TP VPN technologies.
