EP 85: From Colonial Pipeline to Agentic AI: What OT Security Actually Requires

Let’s face it, the Purdue model's DMZ is gone. Trevor Dearing, Director of Critical Infrastructure Solutions at Illumio, explains how zero trust, micro-segmentation, and explicit policy are now the only reliable defense for critical infrastructure OT.

EP 84: Airports as Critical Infrastructure: OT Security and Operational Disruption

Airports illustrate the potential impact of OT attacks that disrupt functionality. Dan Gunter, CEO of Insane Cyber, talks about how industrial environments differ from traditional IT, particularly in their reliance on availability and safety, where disruptions can have significant real-world and financial consequences.

EP 83: Cybersecurity and Risk in a Decentralized Energy Grid

The surge in renewables and decentralized power is reshaping grids—and exposing them to new operational and cyber risks. In this episode, Rafael Narezzi, Co-Founder & CEO of Centrii, explains how rising connectivity widens the attack surface, leaving energy infrastructure increasingly vulnerable.

EP 82: Kerberos in OT: RC4 Downgrade Attacks

Kerberos, a decades-old authentication protocol, creates hidden risks in OT environments. Dor Segal, security researcher team lead at Silverfort, discusses delegation abuse, cipher downgrade attacks, and person-in-the-middle threats—highlighting why legacy encryption, patching challenges, and operational constraints make identity security critical in industrial networks.

EP 81: Root of Trust: Why Security Now Starts in Silicon

Rising software complexity in safety-critical industries is forcing cybersecurity requirements on systems previously not thought about before.  David Sequino, CEO of OmniTrust (formerly ISS), talks about the need to secure digital certificates on life critical systems like cars and planes and the challenges in doing so.

EP 80: The Dangers of White Label Devices

Many devices on modern networks aren’t what their labels claim. This episode, Rob King, Director of Applied Security Research at runZero, explores white-labeled surveillance and IoT hardware, why some vendors are banned by governments, and how hidden risks can spread across enterprises. Discovery, device fingerprinting, and protocol analysis reveal what’s really connected—and why knowing your true inventory is now essential for security, compliance, and trust.

EP 79: Ignore OT Security At Your Own Peril

The growing importance of OT security, highlighting overlooked risks in critical infrastructure, legacy systems, and supply chains. Through real-world examples, Eric Durr, Chief Product Officer at Tenable, shows why OT security differs from IT, emphasizing visibility, resilience, and risk prioritization to protect safety, operations, and business continuity.
 

EP 78: In Defense of Autonomous Vehicles

At Black Hat USA 2025, Dan Berte, IoT Director at Bitdefender, discusses the successes and failures of ride-sharing autonomous vehicles in San Francisco, and how these lessons might help design better IoT integrations of cities and AVs in the future.

EP 77: Building a Cyber Physical System Device Library

Do you really know what’s on your network? A lot of OT devices are white labeled, meaning they have a brand name but under the hood they’re made by someone else. Sean Tufts, Field CTO for Claroty, explains how his team is using AI to sift through all the available data and build a cyber physical library that starts to add specificity to remediation operations, and improve cyber physical security overall

EP 76: Why Security Certs for New Medical Devices Might Just Work

Diversity in healthcare devices complicates segmentation, security controls, and zero-trust approaches. New certifications aim to help. Bob Lyle, CRO of Medcrypt, identifies how layered defenses, rigorous cybersecurity requirements for new devices, continuous monitoring, and dark-web credential surveillance can reduce risk.
