OT Threat Hunting: Why Finding Nothing Is a Good Thing
Summary: Dragos describes OT Watch, a threat-hunting-as-a-service offering that customers can add to any Dragos Platform deployment, as a proactive manual search for malicious activity, suspicious behavior, or vulnerabilities in OT networks. The post argues that an empty hunt can signal effective controls and strong visibility, while also noting that a hunt finding nothing may instead expose gaps in data visibility or monitoring coverage.
Why it matters: Dragos lists misconfigurations - weak network segmentation, outdated PLC firmware, unnecessary open ports, default credentials never changed - as among the most common findings in OT threat hunts, and each is an easy foothold for an attacker. A clean hunt only means something if hunters could actually see every relevant network segment, device, and log.
