Production-Ready Automated Security Analysis & Threat Modeling Platform
ThreatModelerX is an enterprise-grade, open-source security automation platform that integrates SAST (Static Application Security Testing), threat modeling, and risk prioritization to automatically identify, map, and remediate application security risks across multiple programming languages.
