Senior🎓
Top SchoolMark Hallman is a senior technical advisor and digital forensics expert with over a decade of hands-on experience preserving, collecting, and analyzing ESI for Fortune 100 companies, NLJ firms, and U.S. federal agencies including the DOJ, DOL, and SEC. He built and led a regional digital forensics and e-discovery practice in Dallas, developing collection protocols, investigation playbooks, analyst training, and performing hundreds of cyber forensics investigations and expert testimonies in state and federal courts. Technically fluent across Windows, macOS, Linux, iOS, and Android, he brings deep tool expertise (EnCase, FTK, Nuix, X-Ways, Cellebrite, SANS SIFT, IEF) plus 12+ years of SQL database design and administration. At SANS Institute he advises and educates practitioners, blending operational incident response with courtroom-ready presentation skills. Not immediately obvious: his background spans enterprise ERP and Oracle systems leadership, giving him rare visibility into both application-level data flows and low-level forensic artifacts.
