Summary
👤
Senior🎓
Top SchoolChad Duffey is a security engineering staffer with 12+ years of hands-on experience securing cloud and enterprise infrastructure, now focused on infrastructure and service security at OpenAI. He has led security and infrastructure teams at Palantir and Dropbox and brings deep expertise in AWS, Azure, GCP, Active Directory hardening, PKI, fuzzing, exploit development, and automated DevSecOps. Certified at the highest levels (OSCE, OSCP, OSWP, GXPN, GIAC) and a former Microsoft Certified Master for Directory Services, he blends offensive research with pragmatic prevention—deploying mitigations like ASR, WDEG and Credential Guard at scale. Chad also contributes to industry governance as a GIAC Advisory Board member and is slowly working through an MBA while pursuing a Master of AI, showing a mix of leadership, continuous learning and technical curiosity. Not obvious at first glance: his background spans both deep Windows kernel/programming experience and cloud-native automation (Python/PowerShell), enabling him to bridge legacy enterprise identity risks with modern cloud threat models. Based in Sydney, he excels at turning exploit research into deployable security controls for high-risk production environments.
