Build defensible hunts from testable hypotheses to measurable coverage improvements
Form testable hunt hypotheses with defined scope, assumptions, and success criteria.
Translate a hunt hypothesis into MITRE ATT&CK Enterprise technique IDs and observable behaviors.
Choose the minimum log and endpoint telemetry needed to test a hypothesis and identify collection gaps.
Run a hunt from its investigative question through queries, findings, disposition, and next actions.
Use baseline-and-delta thinking to distinguish meaningful anomalies from normal variability.
Apply metrics for findings, detections, coverage, and time costs to guide future hunting.

Define threat hunting, its place in the incident lifecycle, and the characteristics of a defensible outcome. Build clear hypotheses with scope, assumptions, and success criteria.
2 lessonsMap hypotheses to MITRE ATT&CK Enterprise techniques and select the log and endpoint telemetry required to test them, including gaps that limit conclusions.
2 lessonsPlan and execute hunt iterations from questions to final disposition, then use baseline-and-delta analysis to separate meaningful anomalies from normal variability.
2 lessonsProduce reproducible hunt records that support escalation, detection creation, and review, then measure findings, coverage, detections, and time costs.
2 lessonsComplete an end-to-end hunt scenario that applies hypothesis framing, ATT&CK mapping, telemetry selection, analysis, documentation, and outcome measurement.
1 lessonThreat hunting turns uncertain observations into structured investigations that can reveal meaningful security activity. This course develops a practical foundation for framing testable hypotheses, selecting evidence, analyzing results, and documenting decisions so hunt outcomes support follow-up action and measurable improvement. It is designed for security professionals who need a repeatable way to plan, execute, and evaluate hunts.
The course covers hunt workflows, hypothesis framing, MITRE ATT&CK technique mapping, log and endpoint telemetry selection, hunt execution, baseline-and-delta anomaly analysis, documentation, and outcome metrics. It also includes an end-to-end hunt scenario from hypothesis through measurement.
From project managers and operators to founders, analysts, and teams adopting AI, Fenzo is for people who want to get better at the work they already do.
Anything from using AI for project planning and analysis to improving workflows, decision-making, communication, and delivery. If you can describe the skill or task, Fenzo can build a course around it.
Yes. Tell Fenzo what you do, what you’re trying to accomplish, and where you’re stuck, and Fenzo will shape the course around your role, your goals, and the work you actually have to do.
No. Fenzo adapts to your starting point, so you can begin with the fundamentals or jump straight into more advanced work.
Yes. Fenzo for Business puts the whole team on one plan — shared seats, courses you can assign, and reporting on who has finished what.
See Fenzo for BusinessYou start by describing your goal or taking a short skill benchmark. Fenzo uses that context to identify gaps and shape the learning experience around them.

What the science says
Students in lecture-only classes are 1.5× more likely to fail.
How Fenzo does it
Every Fenzo lesson is interactive. No passive reading or watching, ever.

Skill retention over time · with vs. without practice
What the science says
Offloading thinking to AI erodes the very skills you’re trying to build.
How Fenzo does it
Fenzo makes you do the thinking — guided, but never done for you.

Long-term recall · retrieval vs. re-reading
What the science says
Recalling information beats re-reading it for building durable understanding.
