I agree that it&#x27;s perfectly valid, but disagree that it&#x27;s necessary. Deploying proxies has costs - it obscures the endpoints of communication from sensor software and makes anomaly detection more difficult.<p>Richard Bejtlich&#x27;s &quot;Practice of Network Security Monitoring&quot; has a chapter dedicated to the costs and benefits of proxy deployments; I recommend the book for a look at one coherent method of network security monitoring.
