Builder of security products and programs. Teacher of those who run them.
I'm a cybersecurity executive with deep technical roots, product management experience, and a business mindset. I've built security products and programs from early stage to enterprise scale. I'm also a Faculty Fellow at SANS Institute and the creator of REMnux, a popular Linux toolkit for malware analysis. I share perspectives on security leadership and technology at zeltser.com.
The new REMnux MCP server connects AI agents to 200+ malware analysis tools. I was surprised at the depth of investigation it can deliver: https://zeltser.com/ai-malware-analysis-remnux
Most of my time on this project went into capturing how I approach malware analysis and making sure the server provides the right guidance at the right time, so that AI can think and adapt as it creates the workflow. The post includes interactive replays of real analysis sessions.

"A technical postmortem on how one person with zero coding experience built a self-evolving AI swarm across 11 platforms using 900 accounts, 56 GitHub Actions workflows, and $0 in compute costs."

We told employees to "be suspicious" of links they needed for work. Now we're adding "be careful with AI" to the awareness curriculum. Teaching when to escalate works better than teaching what to fear.
