Senior🎓
Top SchoolDavid Longenecker is a seasoned cybersecurity leader with 11+ years in senior roles and nearly three decades of hands-on experience across incident response, threat hunting, malware analysis, and SOC operations. Currently Director of Cybersecurity Operations at Marvell, he previously built and ran global cyber operations and a 24x7 SOC at AMD, and created SIEM and IR programs that scaled across large enterprises. He blends technical depth—network engineering, forensic investigation, red-team skills and a few CVEs—with strategic risk management and compliance experience (HIPAA/HITRUST, NIST CSF, ISO 27001). An active researcher and technical writer, he founded Security For Real People to translate complex vulnerabilities and privacy risks into practical guidance and has published tooling and PoCs (e.g., reglister, TweetThief) used for DFIR and OSINT. Known as a pragmatic defender who still breaks things to learn how to detect them, he pairs an MBA and CISSP/GCFA/GPEN certifications with a communicative style that bridges engineers, executives, and nontechnical audiences.
