It only obscures it if you have a bad setup. Having records of structured proxy logs is fantastic. Without being able to disallow uncategorized and malicious sites, the infection rate at my company would probably triple. Without being able to inspect proxy logs on the fly through our SIEM, we&#x27;d have to request packet captures for every single potential incident, and hope the captures didn&#x27;t roll over.<p>We also do a lot of anomaly detection on the proxy logs themselves. It does obscure NetFlow-based anomaly detection, and does create complications in the architecture, sure, but from my experience with them, the pros outweigh the cons if you set them up properly.
