BlueHat India 2025 Day 1 Keynote covering AI security at the edge, including attack vectors and defensive strategies.
Agentic Security Leader @ Microsoft & Security Researcher
David Weston leads Agentic Security at Microsoft, where he builds the AI models, autonomous agents, and evaluation systems redefining how defenders operate. At Microsoft since the Windows 7 era, he has worked across exploit mitigation design, malware analysis, APT research, and led security engineering for Windows, Xbox, Azure OS, and Microsoft's Offensive Security Research & Engineering group. His current work is leading teams training frontier security models, agentic security systems for defenders, and pushing AI-driven vulnerability discovery through Microsoft's Multi-Model Agentic Scanning Harness (MDASH). A longtime member of the research community and former CISA technical advisor, David is a regular presenter at BlueHat, Black Hat, and DEF CON.

I lead Agentic Security at Microsoft, where I build the AI models, autonomous agents, and evaluation systems redefining how defenders operate. My current work spans training frontier security models, building agentic security systems for defenders, and pushing AI-driven vulnerability discovery through Microsoft's Multi-Model Agentic Scanning Harness (MDASH). I share what we learn so the broader community can raise the bar together.
My background spans vulnerability research, exploit mitigations, red teaming, and building product security programs that survive contact with reality. If you're working on hard security problems, I'd love to compare notes.
