Automated Threat Modeling with AI - How Thr8 Works

Every security compliance framework asks the same question: "Where is your threat model?" And every engineering team gives the same answer: "We will get to it." PASTA (Process for Attack Simulation and Threat Analysis) is one of the most thorough threat modeling frameworks. It is risk-centric, covers 7 stages from business objectives through attack simulation, and produces actionable output. But it takes days of manual work per application. Most teams never start. I built thr8 to automate this. It is a GitHub Action that generates complete PASTA threat models by combining static codebase analysis with AI-powered threat reasoning. This article walks through the architecture, the PASTA methodology, and how it integrates into CI/CD. The PASTA Framework in 60 Seconds PASTA has 7 stages. Most threat modeling tools skip half of them. thr8 covers all 7: Stage Name What thr8 Does 1 Business Objectives Identifies what the system protects and the impact of a breach 2 Technical Scope Detects tech
