Albert Halfmann

 Senior Security Engineer at Chicha Technology with 8 years of hands-on cybersecurity experience and 8 years of military service. I've built SOC platforms, led incident response teams, and worked with federal agencies on critical security initiatives.

 I wrote The Cybersecurity Field Guide because I was tired of the gap between security education and what actually works at 2 AM when alerts are firing. This book teaches the practical skills I use every day—no fluff, just tools and techniques that work.

 Certifications: CompTIA SecurityX, CySA+, AWS cloud certs, and many others.
