The Cisco VPN 3000 Series Concentrators are purpose-built, remote access virtual private network (VPN) platforms that support connectivity mechanisms including IP security (IPSec), Point-to-Point Tunneling Protocol (PPTP), Layer 2 Tunneling Protocol (L2TP) over IPSec, and Cisco WebVPN (clientless secure sockets layer [SSL] browser-based connectivity). Since they are critical components that provide secure access across disparate networks, VPN concentrators need to be monitored 24*7 to ensure that they are operating well at all times. This is where the eG Enterprise lends a helping hand to administrators for continuously monitoring the VPN concentrators.
