Websense TRITON RiskVision

Positioning TRITON RiskVision in the network

RiskVision positioned downstream from a web proxy

In most cases, it is best to position the RiskVision appliance between clients and the
proxy. This ensures that RiskVision components see:



Unaltered TCP traffic from clients



The client IP address associated with requests

Outbound data protection performed by the upstream proxy does not affect
RiskVision, but if the upstream proxy blocks

responses

from origin servers,

RiskVision does not see those responses.
