Threat hunting is an advanced security analysis process that leverages deep knowledge of a network or organization to catch subtler, more deeply embedded attackers than a Security Operations Center (SOC) finds. It is a proactive approach to cybersecurity that involves actively searching for malicious activity on a network. The threat hunting process is divided into three parts: trigger, hunt, and export. The trigger refers to the process by which a hunt begins, usually driven by analyst intuition about something behaving odd on the network. The hunt is an iterative process by which analysts identify something odd about a network, test out hypotheses, and eventually come to a conclusion. The export is the conclusion of the hunt, which results in the hunter coming to a conclusion and communicating that result to the main operations team.

Cliff Stoll, an astronomer-turned-cybersecurity expert, wrote a book in 1989 that predates the fall of the Berlin Wall. In it, he discussed the importance of threat hunting and the need to be proactive in order to protect networks from malicious actors. He argued that it is important to think of the potential threats that could be lurking in the shadows, rather than just relying on the traditional methods of security.

Threat hunting is similar to scientific research, rapid prototyping, or intelligence analysis, but has distinguishing characteristics such as limited data, limited time, fewer universals, and easier prototyping. It is a formally young field, and people have started to compare notes and identify what works. It is important to read outside of the field and look at how engineering and scientific processes work, how intelligence analysis and detectives operate, and work on rapid prototyping to inform hunts.
