Threat Modeling Certification

The Threat Modeling Certification is a free 20-minute skill test from Science of Apps. It tests threat modelling — the four key questions, data flow diagrams, trust boundaries, STRIDE, prioritising threats, mitigations and integrating threat models into delivery. Score 70% or more on its 20 questions to earn a verifiable Threat Modeling certificate (SOA-THRM). Every question is based on published standards and research — including Threat Modeling Manifesto (threatmodelingmanifesto.org), Threat Modeling Tool threats (STRIDE) (Microsoft Learn), Application Security Verification Standard (OWASP) — and each answer is explained with its source.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Threat Modeling certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Threat Modeling Manifesto (threatmodelingmanifesto.org); Threat Modeling Tool threats (STRIDE) (Microsoft Learn); Application Security Verification Standard (OWASP); SP 800-207: Zero Trust Architecture (NIST); OWASP Top 10 for LLM Applications (OWASP); MITRE ATLAS (MITRE). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Modelling the system (Four key questions, Data flow diagrams and Trust boundaries); Threats and mitigations (STRIDE, Prioritising and Integrating into delivery); Threat modelling techniques (Attack trees, PASTA and LINDDUN and Abuse cases); Threat modelling for modern systems (Cloud and microservices, AI and LLM systems and Supply chain). Every question is an original scenario based on a published standard, official documentation or research, named under the question.

We rate it Advanced: assumes years in the role or deep specialist knowledge. It has 20 scenario questions — 5 from each of 4 skill areas — and a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

Employers in 2027 want security engineers, architects and senior developers who find design flaws before code is written: modelling systems with data flow diagrams and trust boundaries, asking what can go wrong using STRIDE or attack trees, prioritising threats by likelihood and impact, agreeing practical mitigations and keeping models current as systems change. It's the cheapest point to fix security. Practise on a real feature and verify with a free 20-minute test.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
