Cisco Cisco Web Security Appliance S690 Guía Del Usuario

from the adaptive security appliance based on its authentication of the 
AnyConnect client, providing an automatic authentication step for the user to 
access web content.

Cisco AnyConnect Secure Mobility is a collection of features across multiple 
Cisco products that extends control and security into borderless networks. The 
products that work together to provide AnyConnect Secure Mobility are the Web 
Security appliance, adaptive security appliance, and Cisco AnyConnect client.

The following figure shows how these Cisco products work together to provide 
AnyConnect Secure Mobility. 

Remote and mobile users use the Cisco AnyConnect Secure VPN client to 
establish VPN sessions with the adaptive security appliance. The adaptive 
security appliance sends web traffic to the Web Security appliance along with 
information identifying the user by IP address and user name. The Web Security 
appliance scans the traffic, enforces acceptable use policies, and protects the user 
from security threats. The adaptive security appliance returns all traffic deemed 
safe and acceptable to the user.

All Internet traffic scanning is done by the Web Security appliance, not the client 
on the mobile device. This improves overall performance by not burdening the 
mobile device, some of which have limited processing power. In addition, by 
scanning Internet traffic on the network, you can more easily and quickly update 
security updates and acceptable use policies since you do not have to wait days, 
weeks, or even months to push the updates to the client.
