With SSL and IPsec virtual private networks (VPNs), businesses can securely connect remote offices and remote users using cost-effective, third-party Internet access rather than expensive dedicated WAN links or long-distance remote dial links.
Organizations can reduce WAN bandwidth costs while increasing connectivity speeds by using high-bandwidth Internet connectivity, such as DSL, Ethernet, and cable, and securing it with encrypted IPsec or SSL VPN tunnels.
VPNs provide the highest possible level of security through encryption and authentication technologies that protect data traversing the VPN from unauthorized access. Organizations can take advantage of the easy-to-provision Internet infrastructure to quickly add new sites or users, and can dramatically increase the reach of their networks without significantly expanding infrastructure.
