Threat Modelling For CISO's 2026 Masterclass

Here's the full Udemy course description — ready to paste:

Most security teams identify threats too late, too informally, and in a language their board will never act on.

This course fixes that.

Threat Modeling for CISOs — 2026 Edition is a practical, lab-driven course that takes you from blank whiteboard to a fully operational threat modeling program. You will learn how to systematically find threats before attackers do, score and prioritise them with industry-standard frameworks, validate them with real adversary simulation tools, and present the findings in dollar-denominated risk language that gets executive buy-in and budget approved.

What makes this course different:

Every concept is immediately applied in a hands-on lab. You will not just learn what STRIDE is — you will apply it to a real payment API, generate an SBOM, scan for CVEs, run a simulated attack in CALDERA, and push the results into a GRC platform automatically. By the end, you will have built a complete threat model for PayFlow, a realistic fintech application, covering its web frontend, cloud infrastructure, AI/LLM pipeline, and CI/CD supply chain.

Inside the course you will:

Build Data Flow Diagrams (DFDs) with trust boundaries in OWASP Threat Dragon and pytm, then apply STRIDE across every element to surface Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege threats with precision.

Score every threat with DREAD and CVSS v3.1, build a prioritised risk register, and calculate Annualised Loss Expectancy using the FAIR model — so you can walk into any board meeting and say "this risk costs us $38M per year in expectation, and a $42K sprint reduces it by 90%."

Threat model cloud-native architectures on AWS — IAM roles, S3 buckets, Lambda functions, VPCs, and Kubernetes clusters. Run Prowler for cloud asset discovery, generate ATT&CK Navigator layers, and validate your controls with MITRE CALDERA adversary simulations and Atomic Red Team.

Integrate threat modeling directly into your CI/CD pipeline with GitHub Actions and pytm — so every code commit automatically checks for new unmitigated threats before it reaches production.

Threat model AI and LLM systems using the OWASP LLM Top 10. You will identify prompt injection, training data poisoning, insecure output handling, and PII leakage in RAG pipelines — the attack surface most security programs are completely unprepared for in 2026.

Map a single threat model to ISO 27001, NIST CSF 2.0, SOC 2, HIPAA, PCI-DSS, and GDPR simultaneously — and push findings automatically into Vanta or Drata via API, eliminating manual compliance evidence collection.

Run advanced tabletop exercises simulating a nation-state APT29 campaign, a LockBit ransomware-as-a-service attack, and a CI/CD supply chain breach — with full inject timelines, role assignments for legal, comms, and the C-suite, and debrief frameworks.

Course highlights:

• 15 modules covering the complete threat modeling lifecycle from DFD to board presentation

• 24+ hands-on labs with full solution slides — CALDERA, Atomic Red Team, pytm, Syft, Grype, Prowler, OWASP ZAP, Threat Dragon

• Full PayFlow fintech capstone — end-to-end threat model built across every module

• FAIR risk quantification lab with a real board one-pager you can adapt immediately

• MedChain AI final exam — threat model a healthcare AI system under exam conditions

• Advanced tabletop scenarios based on real 2024–2025 breach cases

• 20-question assessment quiz and a 60-mark final exam with full answer keys

This course is for you if:

You are a CISO, security engineer, DevSecOps lead, GRC analyst, cloud architect, or penetration tester who wants a structured, tool-driven approach to threat modeling that produces outputs your engineering team can act on and your board can understand.

Your instructor:

Armaan Sidana is an OSCP, CEH, and CISA-certified security professional, founder and CEO of Nexus Security, holder of 7 CVEs, and a Guinness World Record holder. He has secured 100+ companies, mentored 40,000+ students, and built this course from real-world CISO engagements — not textbook theory.

Threat modeling is the highest-leverage security activity you can invest in. A single well-run threat model catches vulnerabilities that months of penetration testing miss — before they become breaches. This course shows you exactly how to do it.
