About

I'm Bryce Maxheimer — cybersecurity professional and U.S. Marine Corps Cyber Warfare Operator veteran with 4+ years of hands-on experience in threat hunting, digital forensics, network defense, and cyber infrastructure management. I currently work as a Shift Lead at the Defense Finance and Accounting Service (DFAS) and hold a TS/SCI clearance with CI Polygraph.

My background spans both the offensive and defensive sides — Red Team Certified Professional out of Marine Corps Cyberspace Operations Group, plus a stack of SANS / GIAC blue-team credentials (GCFE, GCIH, GSEC, GFACT, GPYC). I'm pursuing a B.S. in Applied Cybersecurity at SANS Technology Institute, expected January 2027.
