Hello! I’m an IT and cybersecurity veteran with 27 years of experience across ISPs, banks, manufacturers, government, and many other industries.
Today I focus on offensive AI security - AI/LLM penetration testing, AI red teaming, agentic attacks, and bug bounty work. I work at an AI security startup and teach practical AI hacking on Udemy.
I previously ran a penetration testing company, Cyber 51 LLC, which I sold in 2018. Before that I worked as a senior penetration tester across infrastructure, web, mobile, wireless, IoT, and AI.
