Senior🎓
Top SchoolOsher Jacob is a Principal Researcher with a decade of experience in offensive and defensive security, currently leading research at Palo Alto Networks after senior roles at Cynet, KayHut, and Claroty and foundational work in the Israel Defense Forces. He blends deep reverse-engineering chops with data science—holding an MS in Data Science from the University of Colorado Boulder—to translate exploit discovery into practical, ML-informed protections. Known for breaking systems to understand them, he pairs that curiosity with hands-on hardware tinkering and music-making, which fuels creative problem solving. Colleagues rely on him to bridge low-level technical insight and product-ready security controls across enterprise environments.
