Jeff Holland
Security Engineer at Codecov
Chicago, Illinois, United States
Summary
🤩
RockstarJeff Holland is a Lead Security Engineer with a deep hands-on background in SIEM architecture, orchestration/automation, cloud security (AWS/GCP), and secure software development using Python, PowerShell, Perl and Bash. Over a multi-decade career spanning finance, legal, analytics and SaaS (including Codecov and Sentry), he has built and operated SOAR programs, tuned enterprise SIEMs, led incident response, and driven vulnerability management and compliance (SOC2, ISO 27001, HIPAA). He holds CISSP and other security certifications and pairs practical engineering—custom scripting, connector development and MDM administration—with strategic cloud architecture. Based in Chicago with ties to Portugal, Jeff is as comfortable diving into regex or SIEM content creation as he is shaping security programs for developer-centric platforms. An unusual strength is his mathematical training (BS/MS) informing a methodical, data-driven approach to detection engineering and risk prioritization.
