About this episode

Your host Brooke S., PhD sits down with Matthew Rosenquist, a 24-year Intel cybersecurity CISO and founder of Cybersecurity Insights. Together they discuss AI's growing impact on security, covering practical career advice for newcomers and the urgent risks posed by agentic AI models that can rapidly discover vulnerabilities and compress an attacker's timeline.

Matthew introduces the "Mythos effect," inspired by Anthropic's Mythos Preview, explaining how AI is democratizing cybercrime and disrupting traditional vulnerability management and incident response. They discuss real-world examples of agentic AI gone awry, the gap between current models and sci-fi sentience, and the difficult trade-offs organizations face balancing speed, oversight, and competitiveness. The conversation also covers where boards and executives commonly go wrong, why simply spending more isn't enough, and what parents and everyday users can do to stay safe.
