About Lenny

Lenny Zeltser is a cybersecurity executive with deep technical roots, product management experience, and a business mindset. He's built security products and programs from early stage to enterprise scale, helping businesses succeed rather than just protecting them.

His work draws on over 25 years of experience, a Computer Science degree from the University of Pennsylvania, and an MBA from MIT Sloan. He's a Faculty Fellow at SANS Institute, creator of REMnux (the go-to Linux toolkit for malware analysis), and one of the first to earn the GIAC Security Expert certification.

Student Reviews

  • Slide 1 of 3
    “

    FOR610 was the best course I've taken from SANS. It was demanding but engaging, and Lenny Zeltser is the best. I would sign up for anything he is teaching. I'm looking forward to taking what I've learned with me to work.”

    “

    Lenny Zeltser has put great work into making [FOR610] challenging yet accessible, and he is extremely knowledgeable and good at communicating that knowledge to students. Labs are also really well done, and the lab book plus the live demo walk us through them perfectly.”

    “

    SEC402 covers a very relevant topic, and Lenny Zeltser has not only mastered this topic but also enjoys it. I'm thrilled that there is a writing course specifically for cybersecurity.”
