Overview
The adaptive security appliance delivers unprecedented levels of defense against threats to the network
with deeper web inspection and flow-specific analysis, improved secure connectivity via end-point
security posture validation, and voice and video over VPN support. It also provides enhanced support
for intelligent information networks through improved network integration, resiliency, and scalability.
The adaptive security appliance software combines firewall, VPN concentrator, and intrusion prevention
software functionality into one software image. Previously, these functions were available in three
separate devices, each with its own software and hardware. Combining the functionality into just one
software image provides significant improvements in the available features.
