Greater Chicago Area United States
Summary
👤
Senior🎓
Top SchoolJ Van Beest is a pragmatic cyber security leader with eight years of focused defensive security experience and a broader IT career stretching back to 1999, currently leading global cyber operations at Dexcom. He builds measurable security outcomes through automation—having cut manual hunt time by up to 83% and saved teams significant headcount-costs—while designing purple teams, blue-team-as-code initiatives, and robust vulnerability management programs. J pairs hands-on technical skill (SIEM tuning, threat hunting, vulnerability validation, SOC ops) with strong communication, teaching, and mentorship—equally comfortable explaining security risk to a CEO or coaching junior analysts. He’s entrepreneurial too: founder of a small MSSP and multiple web businesses, bringing a product-minded approach to operational security. Notably, his background in journalism and creative writing helps him translate technical complexity into clear, persuasive narratives that drive cross-functional buy-in.
