Corey Hubbert
An experienced cyber investigations and intelligence professional focused on bringing operationally grounded cybersecurity and investigative services to the private sector. Corey founded CyberD20 to serve businesses, attorneys, and organizations that need work performed at an investigative standard and reported in language executives, counsel, and courts can act on.
Corey is a retired Federal Bureau of Investigation Special Agent with more than 20 years of federal service, where he focused on cyber investigations and cellular analysis & geolocation — work that included Call Detail Record examination, Historical CSLI interpretation, cell-site and sector analysis, and movement reconstruction in support of federal investigations. That same tradecraft now underpins CyberD20's expert-witness practice and litigation-support engagements.
His broader career spans cyber-enabled fraud and network-intrusion investigations, hands-on cybersecurity operations, and instruction. In parallel, he has built and tuned security operations programs — including SIEM engineering and the AI-assisted SOC tooling that powers Hermes.
Engagements are led personally and, when scope requires, supplemented by a small, vetted bench of practitioners — never handed off to junior associates.
