    Your Opinion on AI Doesn't Matter. Learned Fragility Does

    What happens when a tsunami of AI-written code meets a security industry that has spent decades chasing vulnerabilities? Brook S.E. Schoenfield, CTO of Rezliant and author of Securing Systems, returns to warn about "the illusion of omniscient perfection," the cheerful confidence that makes AI output feel finished, and the "learned fragility" that sets in when nobody understands the code anymore. He, Chris, and Robert debate whether an AI threat model that gets 90% of the way there is a win, how Brook now uses AI for reachability analysis, and why prompt injection traces back to a 1975 design principle we ignored. They ask what architecture even means in the age of AI, where the next generation of architects will come from if nobody writes code, and why the collapsing cost of fixes means it's time to stop chasing vulnerabilities.

    Why AI Code Review Will Replace Human Review Faster Than You Think

    Jim Manico thinks the era of human code review is ending, and that clinging to it will hurt your company. The founder of Manicode Security returns to explain why AI didn't kill AppSec education but supercharged it, why vague prompting on frontier models turns companies into "token furnaces," and why prompt injection is the one genuinely new vulnerability class of the AI era. He walks Chris and Robert through his full AI coding workflow, from reverse engineering an architecture file to security rules and planning-mode build plans that make AI output deterministic. The three debate whether AI will finally eliminate SQL injection, whether AppSec vendors can survive without integrating cyber models, and when humans still need to step in: the moment an agent tries something its policy doesn't allow. Plus: the one habit every security leader should teach developers now. This episode is sponsored by Security Compass. Make modern software development secure, consistent, and provable.

    Vulnerability Jail and the AI-Era AppSec Engineer

    Three years ago, Jeevan Singh mapped out what an application security engineer needed to know. AI has rewritten the job since. Jeevan, Director of Security Engineering at Rippling, returns to unpack how his team polices thousands of engineers shipping 10x more code: a "vulnerability jail" that locks non-compliant teams out of the main branch, AI-reviewed extension requests, and homegrown agents that hunt for entire classes of vulnerabilities instead of one bug at a time. He and Chris debate whether AI has killed classic SAST and DAST, whether code review still needs a human in the loop, and whether bug bounty programs still make sense when the researchers on both sides are running the same models. Plus: one concrete move every AppSec leader can make this quarter. This episode is sponsored by Security Compass. Make modern software development secure, consistent, and provable.

    How Agentic AI Fails—and Which Controls Actually Stop It

    Most fault trees get built on gut feeling. Petra Vukmirovic did something rarer: she borrowed the actual math from aviation and nuclear-plant safety engineering and pointed it at AI agents. Petra traded emergency medicine for application security and now heads information security at Numan — and she joins Chris Romeo and Robert Hurlbut to make the case for fault tree analysis (FTA), the deductive method that picks up exactly where threat modeling stops. Petra walks through a "wrong customer refund" AI agent scenario step by step, showing how AND/OR gates and minimal cut sets turn vague worry into ranked, data backed probabilities. They dig into where AI helps build a tree, and where garbage in, garbage out still applies, why "comprehensive test coverage" is a myth, and how attaching real dollar figures to failure paths makes it easier to sell security controls to leadership.

    Your AppSec Bottleneck Is a People Problem

    Most security champions programs don't fail on tooling — they fail on people. Lisi Hocke spent three years as a champion before moving fully into product security, which means she has argued both sides of this from inside the trenches. Drawing on the talk she and Mireia Cano gave at OWASP Global AppSec EU 2026, Lisi walks us through the four things that actually make these programs work: psychological safety first, then cognitive load, then influence when you hold no formal authority, then a champions community so the whole thing doesn't stall the week security goes on vacation. We also get into cutting security wait times, winning organizational support, what AI does and doesn't change here, and why she will tell you never to record the champions meeting.

    AI Pen Testing Killed Traditional DAST

    Is traditional DAST finally dead? James Berthoty came back to settle the argument that his last episode started. James is the founder and analyst behind Latio, and he argues that AI pentesting is a genuinely different animal — payloads generated with context about your actual application, agents that chase findings the way a human tester would, and results a scanner was never going to produce. We get into what it costs once tokens enter the picture, who pays for them, whether a pentest on every pull request is realistic, and what stops an autonomous tester from going further than it should. Then we look further out: the future of bug bounties, what happens when cloud and model providers absorb today's security tooling, and who is accountable when an agent deletes your production database.

    AI Security: OWASP Meets Global Standards

    AI security has no shortage of standards — the problem is turning them into something a team can actually use. Rob van der Veer has spent 34 years in AI and security, founded the OWASP AI Exchange, and created MOSAIC, the agreement that brought eight standards bodies together with SANS to stop the fragmentation. Rob explains what responsible AI really means, what the EU AI Act actually asks of you, and why most AppSec teams are still missing the point on AI-generated code. We also get into agentic red teaming, what happens when agents quietly exceed their scope, and whether AI finally levels the playing field between attackers and defenders.

    The Future of Open-Source Threat Modeling

    You don't have to let AI do the thinking for you. In this episode, Vikram Narayan shares why the smartest teams use AI as an accelerant — not a replacement — and why human judgment still matters most in threat modeling. Vikram created Precogly, an open-source threat modeling platform now running as an OWASP project, and he walks us through what it took to build a free tool on par with commercial vendors. We dig into the tension among speed, compliance, and real risk; whether the Threat Modeling Manifesto needs amending for AI; and what it means to "fight the AI" so critical thinking stays sharp.
