Turn SIEM telemetry into defensible investigations, prioritized alerts, and documented detection improvements
Explain what evidence supports an alert and determine a defensible triage decision within a SOC workflow.
Identify essential log sources and relate normalization to reliable searching and correlation across Splunk and Elastic.
Use SPL and SPL2 patterns, ES|QL filters and aggregations, and EQL sequences to investigate security events.
Translate attacker behavior into correlation ideas, required fields, and MITRE ATT&CK technique mappings.
Validate alerts against raw telemetry, assign severity, and select an appropriate next action.
Document detection decisions, diagnose false positives and false negatives, and propose measured tuning changes.

Define SIEM alert evidence and connect essential log sources to normalized data for dependable searching and correlation.
2 lessonsCompare Splunk and Elastic query fundamentals for filtering, aggregation, time-bounded investigation, and multi-event detection logic.
2 lessonsBuild correlation rules mapped to MITRE ATT&CK, then validate alerts with raw telemetry, severity, context, and next actions.
2 lessonsDocument detection decisions and changes, then monitor and troubleshoot false positives and false negatives through a metrics-and-feedback loop.
2 lessonsComplete a SIEM investigation by querying evidence, validating correlation logic, mapping the behavior to MITRE ATT&CK, documenting the decision, and proposing safe tuning.
1 lessonSIEM alerts become valuable when analysts can connect them to reliable evidence and make defensible decisions. This course develops practical detection and investigation skills across normalized log data, Splunk and Elastic query methods, correlation logic, alert triage, and MITRE ATT&CK mapping. You will leave able to investigate a SIEM case, justify its disposition, document detection changes, and improve detection quality through measured tuning.
The course covers log sources and normalization, Splunk search patterns, Elastic ES|QL and EQL queries, correlation rules mapped to MITRE ATT&CK, evidence-based alert triage, detection change governance, and false-positive and false-negative tuning.
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
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.
