Lenny Zeltser
Summary
👤
SeniorLenny Zeltser is a cybersecurity executive and author with 25+ years of hands-on technical experience and an uncommon blend of product leadership and business acumen from an MBA at MIT Sloan. He has built security products and programs from early-stage startups to enterprise scale, most recently shaping Axonius’s security program and earlier steering product at Minerva Labs and Axonius through critical product-market fit. As a long-time SANS Institute Faculty Fellow and creator of REMnux—the go-to Linux toolkit for malware analysis—he’s trained many incident responders and contributed practical tooling that the community relies on. Lenny combines deep technical chops from system administration, penetration testing, and reverse engineering with proven GTM and risk-management instincts. He’s fluent in translating technical depth into customer trust and business growth, and is now exploring CISO or security product leadership roles while pursuing independent community projects. Expect a leader who writes, teaches, and builds tools as a way to amplify impact beyond the org he serves.
