What problem does it solve? Security work often happens in isolated scans that never turn into actual fixes. This Skill orchestrates a full defense-in-depth program: it runs vulnerability assessments, threat modeling, remediation, infrastructure hardening, and compliance validation as one coordinated multi-phase workflow. ## Core Features & Use Cases - Comprehensive Assessment: Runs SAST, DAST, dependency audits, secrets detection, and SBOM generation, then maps findings to STRIDE threat models and MITRE ATT&CK. - Layered Remediation: Fixes critical vulnerabilities (CVSS 7+), hardens backend APIs, frontend CSP/XSS defenses, mobile apps, and deploys WAF, network segmentation, and secrets management. - Validation & Compliance: Performs penetration testing, verifies OWASP ASVS/CIS/SOC2/GDPR compliance, and sets up SIEM monitoring with incident response playbooks. - Use Case: Before launching a new web platform, run this Skill to baseline vulnerabilities, remediate critical findings, enforce MFA and encryption, and produce a compliance attestation report for auditors. ## Quick Start Run a comprehensive security hardening program against my web application codebase and infrastructure configuration.
