ABOUT GREG WEIR
I lead security operations in a fast-moving, cloud-native financial technology environments. My background spans global financial services, frontline incident response, and high-growth SaaS, giving me a practical view of how real attacks, engineering trade-offs, and business risk intersect.I currently manage Addepar’s global Security Operations and Incident Response function, where I am responsible for detection, response readiness, third-party security assessments, and vulnerability risk across a client-facing investment platform. I work closely with engineering and senior leadership to prioritise risk, maintain resilience, and ensure security supports rather than slows product delivery.Before Addepar, I was a Senior Incident Response Consultant at Secureworks, leading ransomware, nation-state, fraud, and insider-threat investigations for enterprises across multiple industries. I began my career in financial services at Morgan Stanley, where I worked as part of a global CIRT on threat detection, fraud, and phishing response in a large enterprise environment.My focus is operational cyber risk. I care about how attacks actually happen, how controls fail, and how that translates into decisions executives can act on. I also care deeply about building disciplined, high-trust teams, because long-term security outcomes are driven by people as much as technology.
