Senior🎓
Top SchoolGabe Marshall is a Principal Security Consultant and seasoned Red Team engineer with 13 years of hands-on experience designing and executing full-spectrum attack simulations to help organizations find and remediate real-world risks. Based in Spring, Texas, he combines deep offensive skills—custom tooling, payload development, and creative control bypasses—with a strong consulting mindset to translate findings into measurable security improvements. His career spans roles at NCC Group and Fidelity Investments and grew from campus IT and security roles at the University of North Texas, giving him a rare mix of enterprise and operational perspectives. Gabe enjoys the challenge of building bespoke exploit tooling rather than relying solely on off-the-shelf frameworks, which often uncovers issues others miss. He pairs technical rigor with practical remediation guidance, helping clients strengthen detection and response as well as prevention. Outside engagements, his background in emergency management informs a pragmatic approach to incident planning and resilience.
