• Threat model new services and architectures before they ship
• Own the vulnerability lifecycle: risk-based prioritization, SLA tracking, and remediation follow-through with owning teams
• Maintain SAST, DAST, SCA, secrets scanning, IaC scanning, and container image scanning into CI/CD as automated gates
• Harden the software supply chain: build provenance, artifact signing, SBOM generation, dependency governance
• Enforce guardrails as policy-as-code using Azure Policy, OPA/Gatekeeper, or Kyverno
• Review designs and code with engineering teams and support secure deployments

AI/ML Security

• Secure AI/ML development and deployment, including model and data supply chain integrity, inference endpoint exposure, prompt injection and agentic tool abuse, and training data governance

Governance
