DefectDojo is a vulnerability management and application security platform available as both an open-source project and a commercial SaaS offering. The platform centralizes and automates the vulnerability management lifecycle, enabling security teams to aggregate findings from a wide range of security scanning tools into a single unified system. Core platform capabilities include: - Automated triage and deduplication of vulnerability findings - Risk-based prioritization and customizable scoring - Integration with security tools across SAST, DAST, SCA, and penetration testing workflows - Application Security Posture Management (ASPM) - DevSecOps pipeline integration - SOC-oriented workflows - AI-assisted analysis and insights (via "DefectDojo Sensei") The platform is designed for multiple user roles including CISOs, security engineers, AppSec leaders, penetration testers, and managed service providers (MSPs). It supports over 18 security tools and has recorded more than 4 million downloads of its open-source edition. DefectDojo offers a commercial licensing model that departs from per-application or per-user pricing, instead providing a broader license structure intended to give organizations more cost predictability. The open-source community edition is maintained alongside the commercial product. Target users include enterprise security teams, MSPs, and organizations running DevSecOps programs who need to consolidate vulnerability data from multiple scanners and manage remediation workflows at scale.
