  • Lead post-incident reviews, tabletop exercises, and continuous improvement initiatives to strengthen organizational resilience and reduce repeat incidents.
  • Mentor and develop SOC analysts and incident responders, establishing investigation standards, quality controls, and career development pathways.
  • Ensure proper evidence handling, forensic integrity, and audit-ready documentation aligned with regulatory frameworks (e.g., NIST, CMMC, PCI).
  • Identify emerging threats, adversary trends, and attack patterns, and operationalize insights into improved detections, controls, and defensive strategies.
  • Analyze alerts to determine legitimacy and potential impact.
