Why Netskope Let AI Hack Its Own Software

On the latest episode of Security Visionaries, host Emily Wearmouth sits down with Mohit Kulamkolly, senior engineer on Netskope’s security red team, for a candid look at what happens when you point frontier AI models at your own product’s code. Mohit draws on his team’s research (using Claude Mythos and ChatGPT 5.5), explains what a memory corruption bug actually is, and why it remains one of the hardest and most dangerous flaws to find. From building isolated sandbox labs that let AI agents hunt for crashes, to a second experiment where the AI got more control and its findings were checked by a completely separate AI, Mohit walks through two very different ways of putting these models to work. The discussion explores why you can never just trust a model’s claim that it found a bug, how sub agents kept the hunt moving for days without giving up, and why AI is even more useful earlier, threat modeling a product before it’s built, than after the fact. Mohit and Emily also tackle what this means for security teams that don’t have frontier model access yet, and why finding thousands of vulnerabilities is only half the job without a real remediation plan. This episode’s bottom line? AI is changing vulnerability research at every level, and the security teams that get ahead of it will be the ones that give it the right tools early.

The AI Public-Private Divide

On the latest episode of Security Visionaries, host Bailey Popp sits down with Teresa Carlson, Global Head of Public Sector at Anthropic and former CEO of the General Catalyst Institute, for a wide-ranging conversation on the intersection of AI, cybersecurity, and public-private collaboration. Teresa draws on nearly three decades in technology to share what it truly takes to work with government. From navigating compliance frameworks like FedRAMP to building sponsor networks that accelerate the path to authority to operate. The discussion explores how security leaders can shift from a checklist culture to an outcomes-based mindset, and why going in as a partner, not a vendor, is the defining factor for success. Teresa and Bailey also tackle the fragmented global AI regulatory landscape, the challenge of data sovereignty, and why startups bear a disproportionate burden in a world of conflicting mandates. This episode's bottom line? AI is minting a new generation of citizen developers and the opportunity has never been bigger.

Live @ RSAC 2026: AI FOMO

On the latest episode of Security Visionaries, host Max Havey and guest James Robinson, CISO at Netskope, connect live and in-person at RSAC 2026 to discuss the cutting edge of security in the age of AI, particularly for highly regulated industries. They dive into the conference's biggest trends, focusing on the rise of agentic AI, the necessity of heavy guardrails, and the complex challenge of data sovereignty in a global regulatory landscape. James offers insights on the major hurdles facing highly regulated industries as they adopt AI, and shares practical advice for security leaders on shifting their AI governance approach from "no" to enablement. The discussion also covers innovative data governance strategies like moving from data classification to detailed data categorization, and the critical importance of utilizing red teaming and incident investigation to build robust defenses against emerging threats like prompt injection. If you couldn’t make it to the conference, hopefully this will fill you in on some of what you missed.

Crucial Conversations With Your CEO

In this episode of Security Visionaries, host Emily Wearmouth welcomes Nycholas Szucko, a board member for many security companies who is based in Brazil, to discuss better approaches to solving misaligned communication between CEOs, boards, and security leaders. Using key data points from the Crucial Conversations report as a jumping off point, Nycholas offers practical strategies for CISOs and CIOs to bridge the gap. Together they cover the essential skills needed, from communication and storytelling to selling skills and understanding financials. They also offer advice around becoming a CEO’s "trusted lieutenant," determining your CEO's risk appetite (even using AI role-play for preparation), navigating frustration with technology as a "black box," and shifting investment from short-term "band-aid" fixes to strategic, long-term platform modernization. This episode provides constructive approaches for improving alignment, becoming proactive in strategic planning, and leading the business into the age of agentic AI. This conversation is a must-listen, whether you’re a CEO, board member, security leader, or anything in between.

Taking the Fear out of Risk

In this episode of Security Visionaries, host Max Havey speaks with Beth Miller, Field CISO at Mimecast and author of Risk Reframing: How to Navigate Uncertainty With Resilience , about moving to a human-centered approach to cybersecurity. They discuss why fear-based training is ineffective, how the rise of AI makes human judgment more critical than ever, and how security leaders can redefine risk from a negative to an opportunity to "dare." Additionally Beth introduces some frameworks as practical tools for shifting security culture from one of control and compliance to one of resilience and navigation.
