🎙️ Ground Level AI Podcast | Joshua Saxe on AI security, Meta, and the cyber threats that actually matter

Former Meta Llama security lead and Abundant Security cofounder Joshua Saxe explains why the biggest AI security risks may not be the ones making headlines—and why defenders need access to frontier AI

Welcome to the first episode of the Ground Level AI Podcast! I’m excited to offer up thoughtful conversations with AI leaders with a strong focus on what happens when AI meets the real world. From AI infrastructure and cybersecurity to enterprise adoption, policy, geopolitics and the workforce, we'll explore where the technology collides with reality.

My first guest is Joshua Saxe, cofounder and CTO of Abundant Security and the former engineering lead for Llama security at Meta. I've been writing about AI security for several years, and lately it's become one of the hottest topics in AI, driven by concerns about increasingly capable models like Anthropic’s Mythos; worries about autonomous cyber attacks; and growing fears over what AI could mean for critical infrastructure and national security.

We discuss:

  • Why Saxe believes AI security headlines often focus on the wrong threats

  • Whether restricting powerful cybersecurity models actually makes defenders less safe

  • Why we haven’t yet seen a truly catastrophic AI-enabled cyberattack

  • What agentic AI means for attackers—and defenders

  • What it was like leading security for Meta’s Llama models

  • Why Saxe left Meta to launch Abundant Security

  • Why cybersecurity organizations need to rethink how they work in the age of AI

  • What he expects to hear at Black Hat and DEF CON this year

I hope you enjoy it, and I'd love to hear your thoughts in the comments!
