Conor Sherman

Zero Signal is a podcast for CISOs and senior security leaders who are expected to have answers about AI risk before the industry has standards. We go after the strategic questions that don't yet have clean answers — the ones your board is asking and the industry is still debating. Each episode is an honest conversation with someone navigating that pressure — not with perfect answers but with principles, frameworks, and lived experience. We host guests who've had to make real calls under uncertainty and are willing to talk about what worked, what didn't, and what they're still figuring out

    Loris Degioanni: Headless Security and the Coding CISO

    Welcome back to Zero Signal! In this episode, Conor Sherman and Stuart Mitchell are joined by cybersecurity royalty: Loris Degioanni, the co-founder of Wireshark, founder and CTO of Sysdig, and the creator of Falco, the open-source standard for cloud-native runtime threat detection. Loris steps up to break down a revolutionary new architectural paradigm: Headless Cloud Security. Following the release of Sysdig's brand new model for agentic defense, Loris explains why the era of security teams staring at dashboards and clicking through complex UIs is dead. With exploit windows rapidly collapsing down to mere minutes, the interface must entirely disappear into the environment where coding agents live. In this conversation, Conor, Stu, and Loris discuss the shift toward flattening security organizations and the rise of the "Coding CISO". They challenge the failing legacy strategy of baking checklists into standalone agents, arguing instead for injecting security and hard-coded expertise directly into the substrate of development tools via open-source communities, MCPs, and plugins.

He is the co-founder of Wireshark, the world's most widely used network protocol analyzer, and the founder and CTO of Sysdig. An open-source pioneer, Loris also created Falco, the CNCF graduated standard for cloud-native runtime threat detection. He holds a PhD in Computer Engineering from Politecnico di Torino and actively contributes to re-architecting cybersecurity for the agentic era. 01:17 Rebuilding the Operating Model Around Coding Agents 01:54 Defining Headless Security: Moving Beyond Dashboards 03:34 The Disappearing UI: Consuming Software Inside the Agent 06:53 Prioritizing Outcomes Over Problems: The Death of Point-and-Click 08:18 Shifting Beyond Traditional Vulnerability Prioritization 09:55 Tech Layoffs and Flattening Organizations: Everyone Becomes a Contributor 11:31 Rise of the "Coding CISO": Why Executives Must Get Hands-On 12:38 Building GRC and Security Tooling in Hours with Claude Code 13:46 Blending Architectural Vision with Agent Management Skills 15:21 The Defensive Paradox: Why AI Will Increase Cyber Headcount 18:04 The Three Technical Pillars of 2026 Tech Stacks 20:32 Rediscovering the "Love of the Game" Through Prompt-Driven Creativity 24:12 The Timeline of Failing Strategies: Trying to Bake Security Into the Agent 25:34 The Evolution of Substrate Security: From AutoGPT to 4.6 Models 28:44 The Friction of Tool Fragmentation vs. Centralized Ecosystems 31:37 Private Enterprise LLMs: The Safe Way to Handle Token Costs 34:11 Democratizing Software Development: The Marginal Cost of Code Hits Zero 37:40 Overcoming the Enterprise Fear of Open-Source Foundation Integration 40:20 Defining "Skills" in the Headless Architecture (Integrations, Skills, Facilitation) 41:38 Encoding True Engineering Expertise into AI Plugins Hampton North is the premier US based cybersecurity search firm.

    Sounil Yu: How to Solve Problems & Manage Predicaments

    Welcome back to Zero Signal! In this solo episode, Conor Sherman sits down with Sounil Yu—Cybersecurity Hall of Fame inductee, SANS Lifetime Achievement Award recipient, and Chief AI Safety Officer at Knostic. Sounil delivers a masterclass on navigating shifting security landscapes. He breaks down the difference between a "problem" (technologically fixable) and a "predicament" (a systemic risk to manage), such as collapsing exploitation timeframes following the release of "Mythos". Conor and Sounil also unpack why traditional TPRM questionnaires fail, how AI coding agents help teams replace "sick legacy pets" with "cattle" architectures, the Zero Trust renaissance, and why 10x-ing individual cognition will trigger organizational chaos without proper structural reorgs.

    Matt Peters on the AI “Captain America Serum” and Rebuilding the Broken Enterprise Foundation

    Welcome back to Zero Signal! In this special solo-host episode, Conor Sherman sits down with Matt Peters, co-founder and CEO of Fixify. With a powerhouse pedigree as the former Chief Product Officer at Expel and VP of Worldwide Operations at Mandiant during the height of the APT era, Matt brings a unique perspective on the intersection of cybersecurity heritage and IT transformation. Matt breaks down the reality behind the "AI productivity" hype, unpacking Fixify’s 2026 Benchmark Report. While AI allows organizations to resolve tickets 16 times faster, first response times remain identical—highlighting a critical gap in human expectations versus machine efficiency. They discuss why 95% of GenAI pilots fail not because of the technology, but due to a "poverty of vision" and misaligned organizational incentives. In this conversation, Conor and Matt explore how AI acts as a "Captain America serum" for businesses, the collapse of the zero-day patching clock to under 24 hours, and why the next era of leadership requires "systems thinking" over simple domain expertise.

    Matt Stamper: The 4 Classic Failures AI Just Made Existential

    Welcome back to Zero Signal! In this episode, Conor and Stuart are joined by Matt Stamper, co-author of the CISO Desk Reference Guide and chair of the FBI InfraGard CISO Cross-Sectional Council. With experience spanning Gartner research and national critical infrastructure, Matt dives into the "four persistent failures" that AI is rapidly turning into existential risks: identity governance, data governance, third-party risk, and vulnerability management. Matt explains why the "Hustle Hard" era of manual triage is fundamentally broken. As attack timescales collapse from weeks to seconds—evidenced by AI-driven compromises occurring in under eight minutes—security leaders must shift from a "secure-first" mindset to one of radical resiliency and "continuous zero-day" preparedness. In this conversation, Conor, Stuart, and Matt discuss the necessity of "autopilot" for security operations, the legal and geopolitical fallout of "Glasswing" and "Mythos" level capabilities, and why boards must move past the "single slide" and lean into the technical details of enterprise risk.

    “The Hustle Hard Era is Over”: Crystal Morin on How to Move Beyond the Human Ceiling

    Welcome back to Zero Signal! On this episode, Crystal Morin, Chief Cybersecurity Strategist at Sysdig and author of the Sysdig Cloud Native Security and Usage Reports, discusses findings showing vulnerability management has hit a “human ceiling,” with about 5.5% of workloads still running critical/high vulnerabilities year over year despite better tooling.  Morin explains why backlog volume and faster exploitation push organizations toward automation and agentic AI, highlights a major drop in exploitable vulnerabilities in production (to under 0.2%), and notes reduced image bloat (unused packages under 1%) as both cost and risk reduction.  In this conversation, Crystal, Conor, and Stu discuss how threat actors use AI to exploit CVEs within hours, identity trends and new messy identity governance concerns, and growing autonomous response actions like a 140% increase in “kill process.” They also discuss LLM jacking, regional AI package adoption led by EMEA, and McKinsey’s takers/shapers/makers framework.

    The Future of Threat Detection is here -ft Founders of Embed Security

    On the Zero Signal Podcast, the hosts preview RSA micro-events and then interview Embed Security co-founders Seth Summersett (CEO) and Jeffrey Johns (CTO), who launched the company in 2024 after careers at NSA, FireEye/Mandiant, Google, Meta, and others. They discuss the SOC’s operational crisis—thousands of daily alerts, manual triage, burnout, and uninvestigated incidents—and how Embed aims to reduce investigation time and alert noise using agentic AI with human oversight, transparency, and a “chain of evidence” that shows its reasoning. They argue the analyst role will shift toward validating AI-driven investigations, that organizational context and feedback are key, and that investigation, detection engineering, and threat hunting will converge. They cite customer results such as ~90% reduction in false positives and ~155 hours saved per month, predict major disruption to MDR/MSP economics, and emphasize domain-specific models and trust-building metrics.
