Huntsville, Alabama, United States
Summary
🤩
Rockstar🎓
Top SchoolJames Tubberville is a chief security engineer and seasoned red team leader with over two decades of hands-on experience across CISO, threat operations, and SOC/NOSC leadership roles. He blends practical offensive expertise—authoring Red Team Development and Operations and SANS SEC564 course material—with executive-level security strategy and global network operations oversight. Based in Huntsville, he has led threat emulation, penetration testing, and physical security assessments at scale, translating adversary tradecraft into measurable risk reduction. His work bridges technical, operational, and training domains, enabling organizations to mature defenses through realistic exercises and curriculum development. An MBA from Columbia complements his technical BS in IT, allowing him to align security engineering to business priorities and measurable outcomes. Less obvious: he maintains a public presence (ThreatExpress) and a concise GitHub handle (@minis_io) that reflect a focus on sharing pragmatic threat intelligence and tooling rather than broad open-source fame.
