- Validate findings without disrupting production systems by engineering guardrails, safety checks, and rollback plans
- Model threats and map exploit scenarios to prioritize remediation and reduce exposure
- Investigate threat intelligence to align validation scenarios with current attacker tactics and techniques
- Collaborate with engineering teams to communicate risk, propose fixes, and confirm remediation effectiveness
Requirements
