   Turning Cyber Risk Into a Decision You Can Defend

   Patrick Miller sits down with Scott Kannry, co-founder and CEO of Axio, to work through cyber risk quantification as a security decision tool for OT and critical infrastructure. Scott came up in the insurance industry at Aon in the early days of cyber coverage. He founded Axio with Dave White to close the gap between a technical security program and a number a CFO and a board can act on. The conversation stays practical. Why you start on the impact side instead of arguing about probability. How NERC CIP already thinks in consequence. Why the events that matter most are rare, huge, and short on data. How to compare controls, insurance, and compliance spend on the same dollar scale. What AI and quantum do to the "it will never happen" excuse. And a new D&O option for CISOs built on top of consistent quantification. Full show notes, links, and the episode transcript are on the Ampyx Cyber episode page at ampyxcyber.com/podcast. Topics covered: The founding of Axio and the insurance-meets-frameworks origin A short history of cyber insurance, from data breach to business interruption to cyber-physical The four loss categories Axio uses, first and third party, financial and tangible Coverage gaps for industrial facilities and the danger of assumed coverage Impact-first quantification versus probability-first modeling NERC CIP and consequence-only risk rating Fiduciary duty, duty of care, and defensible decisions Security decision support versus vanity security metrics The art and science of pricing control ROI AI and quantum, and why low-probability high-impact events deserve attention now A D&O insurance option for CISOs tied to consistent quantification

   The Attack Surface You Eat: Cyber Risk in Food and Agriculture

   The Attack Surface You Eat: Cyber Risk in Food and Agriculture Kristin King joins Patrick Miller to make the case that food cybersecurity is not food security, and that food and agriculture is one of the most under-defended corners of critical infrastructure. From precision agriculture and processing plants to aquaculture, zoos, and aquariums, they trace where the OT and ICS risk actually lives, why the regulatory floor is so thin, and how the threat range runs from opportunistic ransomware to nation-state targeting and agroterrorism. Guest: Kristin King, founder and CEO of AnzenSage, CEO and co-founder of AnzenOT, host of the Bites & Bytes Podcast, and author of Securing What Feeds Us: Cybersecurity in Food and Agriculture (Wiley).

   Policy Pulse: Regulatory Roundtable - Cyber Strategy, Large Loads, AI & CISA in Flux

   Patrick Miller reconvenes with Joy Ditto (Joy Ditto Consulting) and Earl Shockley (INPOWERD) for a tour of the past two months in critical infrastructure policy. The episode opens on the administration's new National Cybersecurity Strategy and its six pillars, with focus on the openly offensive "shape adversary behavior" posture and the asymmetric risk it creates for asset owners likely to absorb retaliation. The panel then digs into the pressures reshaping the bulk electric system: data center designation, cloud-hosted control centers running NERC standards while the underlying compute is unregulated, and the physics of computational loads that behave nothing like traditional load. Earl walks through the recent NERC Level 3 alert on large load connections, an unusually serious signal that industry processes are behind. The discussion also covers April infrastructure executive orders that release funding but ignore cybersecurity, hyperscalers displacing utilities as the top buyers of bulk electrical equipment, the multi-agency zero trust in OT guidance, and CISA's leadership uncertainty after Sean Plankey withdrew his nomination. On the AI front, the group unpacks what Anthropic's Mythos and the Glasswing response mean for vulnerability discovery at scale, and why no OT vendors are on the Glasswing list. Closing thoughts include Joy's note on satellite cybersecurity and a rare bipartisan Senate trip to China, Earl's emphasis that computational load is now an enterprise governance issue rather than a technical one, and Patrick's plea to stop making the adversary's job easy. Topics covered The new National Cybersecurity Strategy (https://www.whitehouse.gov/releases/2026/03/white-house-unveils-president-trumps-cyber-strategy-for-america/) and its six pillars Offensive cyber posture and the asymmetric risk to asset owners Data center designation as critical infrastructure Cloud control centers and the NERC 100-series standards Computational load (https://www.nerc.com/globalassets/programs/bpsa/alerts/2025/aggregated-report-level-2-large-load-interconnection-study-commissioning-and-operations.pdf), grid stability, and loss of system inertia NERC Level 3 alert (https://www.nerc.com/newsroom/nerc-issues-level-3-alert-reliability-guideline-focused-on-large-load-challenges) on large load connections April infrastructure executive orders (https://ampyxcyber.com/blog/funded-not-secured-the-april-20-dpa-determinations-and-the-bulk-electric-system) and the missing cyber language Supply chain shifts and hyperscalers as the top equipment buyers Zero trust principles for OT environments (https://www.cisa.gov/resources-tools/resources/adapting-zero-trust-principles-operational-technology) CISA Fortify (https://www.cisa.gov/topics/industrial-control-systems/ci-fortify) guidance and CISA's current leadership status Anthropic's Mythos (https://red.anthropic.com/2026/mythos-preview/), the Glasswing (https://www.anthropic.com/glasswing) response, and the OT vendor gap Satellite cybersecurity and bipartisan engagement on China policy Basic hygiene: get exposed devices off the internet

   Vulnerability Overload: Making Prioritization Work in the Real World

   In this episode, Patrick Miller speaks with Kylie McClanahan, CTO at Bastazo, about the practical (and often messy) realities of patch and vulnerability management in operational technology (OT) environments. Kylie shares grounded insights into patching challenges, the gaps between IT and OT remediation cycles, and the real-world implications of relying too heavily on scoring systems like CVSS. The conversation covers CISA’s Known Exploited Vulnerabilities (KEV) catalog, exploring how it’s being used (and possibly misused) in prioritization workflows, and where the disconnects lie between policy directives and operational feasibility. Kylie also critiques the current state of vendor responsiveness, machine-readable vulnerability disclosure (CSAF), and the importance of asset and exposure awareness. This episode is essential listening for practitioners wrestling with patching fatigue, program prioritization, and the tradeoffs between theoretical vulnerability data and applied security outcomes in critical infrastructure environments.

    Simplifying ICS Security Metrics

    Getting started with ICS and OT security metrics can be hard. What do you measure? How do you represent it? Do you even have the data? In this podcast, we talk with Erin Torruella to share her experience from building and managing metrics for multiple different sectors. She provides great advice on where to start and how to get the effort going in the right direction. ChatGPT response was… Operational Technology (OT) and Industrial Control Systems (ICS) are crucial components of critical infrastructure, and their security is essential for ensuring the safety, reliability, and availability of essential services. To measure the success or failure of an OT/ICS security program, several metrics can be considered, such as: 1. Vulnerability Management Metrics: This metric measures the number of vulnerabilities identified, the number of vulnerabilities remediated, and the time it takes to remediate the vulnerabilities. 2. Incident Response Metrics: This metric measures the effectiveness of the incident response process. It includes the time it takes to detect, contain, and resolve an incident, as well as the number and severity of incidents. 3. Compliance Metrics: This metric measures compliance with relevant security standards, regulations, and policies. It includes the number of audits conducted, the number of non-compliances identified, and the time it takes to remediate non-compliances. 4. Risk Management Metrics: This metric measures the effectiveness of the risk management program. It includes the number and severity of risks identified, the number of risks mitigated, and the time it takes to mitigate the risks. 5. Awareness Metrics: This metric measures the effectiveness of the security awareness program. It includes the number of training sessions conducted, the number of employees trained, and the level of understanding demonstrated by employees. 6. Asset Management Metrics: This metric measures the effectiveness of the asset management program. It includes the number and types of assets identified, the level of asset classification, and the accuracy of the asset inventory. 7. Performance Metrics: This metric measures the performance of the OT/ICS infrastructure. It includes uptime, availability, and response time. Thanks for listening! Show links: Erin Torruella...
