Rockstar🎓
Top SchoolDavid Windsor is an engineering manager and kernel security specialist with 11 years of experience building and leading teams focused on Linux kernel self-protection, eBPF, and SELinux. Currently leading Hypershield at Cisco and serving as an upstream maintainer for Falco’s driverkit, he combines product-scale leadership with deep low-level systems expertise. His prior work includes hardening mainline Linux with PaX/grsecurity features, developing large-scale EDR capabilities deployed across millions of nodes, and contributing probes and tests to the widely used Falco libs repository. Known as an OSS hacker, he emphasizes code quality and maintainability—evident from license, formatting, and review-driven improvements in security-critical projects. Based in Washington, D.C., he brings a rare blend of hands-on kernel development and security program leadership that moves defensive controls from prototype to fleet-wide production.
