Overview 
This document provides guidance on selecting a mechanism for redirecting web traffic to Cisco Cloud Web 
Security (CWS). 
The traffic redirection methods currently in use by customers are: 
 
ASA platforms 
 
ISR platforms 
 
CWS Connector 
 
WSA Connector 
 
Direct-To-Tower methods (Hosted PAC files, third-party proxies, explicit browser configuration) 
 
AnyConnect 
 
Selecting a Method to Redirect Web Traffic 
The process of selecting a traffic redirection method is captured in Figure 1 below, and is applicable to most 
customer environments. 
 
 
 
Figure 1: Traffic redirection methods
 
Customers who own Cisco hardware (ISR, ASA, or WSA) are encouraged to leverage the integrated traffic 
redirection capabilities of their platforms. For all other environments, the choice of traffic redirection is between the 
CWS Connector, the WSAv Connector or Direct-To-Tower methods.
