Security AutoDesigner is a cloud-based, automated Threat Analysis and Risk Assessment (TARA) solution designed for automotive OEMs and Tier-1 suppliers. It leverages AI and a comprehensive, automotive-specific threat database to generate detailed TARA reports for vehicles and electronic control units (ECUs), ensuring compliance with ISO/SAE 21434 and UNR 155 regulations. The platform automates the traditionally manual, time-consuming TARA process, reducing human error and accelerating time-to-market. Security AutoDesigner supports both vehicle-level and component-level analysis, integrates with requirements management tools, and adapts to changes in product architecture. It uses the STRIDE threat modeling framework and incorporates the latest threats identified by PlaxidityX’s research team. The tool is designed to streamline regulatory compliance, improve cybersecurity posture, and provide clear, actionable risk assessments for automotive product development.
