   As Product Owner for Endpoint Security at Liberty Mutual, I lead the strategic development and continuous enhancement of EDR capabilities protecting over enterprise endpoints. I collaborate cross-functionally with engineering, threat intelligence, SOC, and governance teams to align endpoint controls with adversary TTPs and frameworks such as MITRE ATT & CK and NIST CSF. During the 2024 global CrowdStrike outage, I provided cross-functional leadership to coordinate stakeholders across engineering, operations, and cybersecurity, enabling my team to restore controls and visibility quickly while ensuring aligned communications and business continuity planning. My work integrates purple team feedback into policy configurations, supports detection roadmap planning, and improves risk reporting through data-driven control coverage metrics. I also serve as the agency lead for corporate volunteer efforts, helping build engagement across diverse teams while reinforcing our culture of shared mission and resilience.
