[Defender Fridays] From PentestGPT to Production: The state of AI-assisted offensive security with Charles Grandjean - May 22

Host: Charles Grandjean, CTO and Co-founder of Hexiagon AI

Topic: From PentestGPT to Production: The State of AI-Assisted Offensive Security

The conversation will cover what AI-assisted offensive security actually looks like in production in 2026, past the marketing, into real engagements. Where AI genuinely shifts the needle in a pentest, and where it still falls apart. Why is the structural change parallel to attack surfaces rather than smarter models? And what all of this means for defenders: detection priorities, patch SLAs, and SOC noise budget when a credible engagement costs the price of lunch.
