What is Cyber Threat Hunting?

Understanding Cyber Threat Hunting

Cyber Threat Hunting flips the traditional security approach on its head—instead of waiting for alerts to trigger, hunters proactively search for attackers who have evaded automated detection. It's based on the assumption that sophisticated threats may already be inside your network, operating stealthily to avoid triggering alerts. Effective threat hunting combines technical tools with human intuition and creativity. Hunters develop hypotheses about potential attacker behaviors based on threat intelligence, recent incidents, or known vulnerabilities in the environment, then search for evidence that would confirm or disprove these hypotheses. They typically leverage data from multiple sources—endpoint telemetry, network traffic, authentication logs, and cloud activity—looking for subtle anomalies or patterns that might indicate malicious activity. Organizations that implement mature threat hunting programs typically identify threats much earlier in the attack lifecycle, reducing dwell time and limiting damage. These programs work best when hunters have freedom to explore hunches and investigate anomalies without being constrained by formal processes.
