[RE-RELEASE] Clint Gibler on AI Revolutionizing Cybersecurity

Welcome back to Zero Signal! In this special re-release, Conor Sherman and Stuart Mitchell sit down with Clint Gibler— currently leads Cybersecurity at OpenAI, former Head of Security Research at Semgrep, creator of the TLDRsec newsletter, and host of the Modern Security Podcast. Recorded live at Black Hat, Clint breaks down how artificial intelligence is rewriting the playbook for application security, vulnerability discovery, and developer workflows. AI is rapidly transforming cybersecurity, moving from a speculative future tech to an active force automating penetration testing and reshaping how security teams interact with codebases. In this conversation, Clint examines the practical implications, cost structures, and future prospects of deploying AI in security pipelines. The group explores the emergence of "vibe coding," the critical need to make security completely invisible to software engineers, and the structural shift toward a "shifting down" security approach. Whether you are managing junior pen testers or architecting enterprise AI adoption, this episode provides a grounded framework for balancing automation with human-in-the-loop oversight. More Conversations from Black Hat: The Zero Signal team will be in attendance on the ground again at Black Hat USA 2026, catching up with industry pioneers and capturing more amazing conversations on the cutting edge of cyber defense.
