Build the threat analysis skills needed to connect security controls, evidence, and risks in a small accounting firm
Explain confidentiality, integrity, and availability for firm assets and associate each property with a control and detection signal.
Build an end-to-end attack path across trust boundaries, identifying prevention and detection points at each step.
Recognize phishing, malware, authentication failures, and configuration weaknesses through relevant email, host, network, and log evidence.
Distinguish how MFA, patching, secure configuration, segmentation, and backups limit threats and support detection or recovery.
Create a basic threat model for the firm that links assets, trust boundaries, threats, controls, detections, and validating evidence.

Define the CIA triad for a small accounting firm and trace how threat actors move through assets and trust boundaries, with prevention and detection points attached to the path.
2 lessonsExamine phishing, social engineering, malware, ransomware, authentication, and MFA as routes into the firm and as sources of analyst evidence.
3 lessonsEvaluate patching, secure configuration, network segmentation, and backups as controls that reduce exposure, limit spread, and support ransomware recovery.
2 lessonsProduce a basic end-to-end threat model for the firm, linking assets, trust boundaries, threats, controls, detections, and validating evidence.
1 lessonThe CIA triad provides a practical way to assess what a small accounting firm must protect and why. This course develops beginner analyst skills through a consistent 40-person accounting firm case, connecting attack paths, social engineering, malware, authentication, system weaknesses, network design, and recovery. By the end, you can produce a basic end-to-end threat model and explain which control addresses each threat and what evidence supports it.
The course covers confidentiality, integrity, availability, threat actors, attack paths, phishing, malware, ransomware, authentication, MFA, patching, secure configuration, network segmentation, backups, and threat modeling. It also covers prevention, detection, response, telemetry, and evidence analysis for a small accounting firm.
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.

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.
