About this product
Threat modelling is easier when you start from something filled in. This set contains sixty worked threat models for architectures teams actually build: a SaaS with teams, a public API, a mobile app with a backend, a payment flow, a file-upload service, webhooks, an admin panel and more.
Each template has a data-flow diagram, a STRIDE table of threats, the mitigations that matter, and test cases you can turn into automated checks. Your fare unlocks architectures in order.
You choose the fare: anything from €1 to €100, in whole euros. At €100 you get every part, plus all future additions to it.
