What is threat hunting?
Threat hunting is the proactive search for active threats inside an environment, without waiting for an alert to fire, typically driven by a hypothesis about adversary behavior, a piece of threat intelligence, or an unexplained anomaly.

Threat hunting differs from alert-driven investigation in that it starts with a question the hunter asks of the data, not a notification from a tool. Hunts are typically conducted by Tier-3 analysts or dedicated hunt teams. The work demands deep system knowledge, adversary tradecraft familiarity, and the ability to formulate a hypothesis that can be tested against telemetry. Successful hunts find threats that bypassed detection.
How Command Zero handles Threat Hunting.
Command Zero treats threat hunting as a first-class investigation mode. Hunters formulate hypotheses as questions, draw on the encoded library of expert questions for related techniques, and run cross-source queries through the Federated Data Model. The Question-based method captures the hunt as a reusable asset: a successful hunt becomes a question other analysts can run against new data, so hunt expertise compounds across the team. The Casebook archives every hunt for audit and knowledge transfer.
