Nexus: A Claroty Podcast

Tatyana Bolton, Executive Director of the Operational Technology Cybersecurity Coalition (OTCC), joins the Nexus Podcast to discuss a new partnership between OTCC and the International Society of Automation (ISA), alongside a joint position paper advocating for the ISA/IEC 62443 standard as the definitive global benchmark for operational technology (OT) cybersecurity.

Ben Gardiner, senior cybersecurity research engineer for the National Motor Freight Traffic Association (NMFTA), joins the Nexus Podcast to discuss research he published on a silent patch released by vendor Bendix addressing serious cybersecurity vulnerabilities in brake controllers found on tractor trailers. The vulnerabilities—which were updated as part of a safety recall—posed safety risks to drivers and others on the road. 

Ben explains how and why he chose to reverse-engineer the safety recall and how the vulnerabilities impact the security of any trailer-connected telematics devices, and also how they could be exploited at close range.

Remedio cofounder and Chief Executive Officer Tal Kollender joins the Nexus Podcast to discuss the challenges and security gaps enterprises and critical infrastructure organizations face with insecure configurations and other risky exposures. As AI and advanced attackers accelerate the speed at which exposures are uncovered and exploited, organizations are beginning to consider automated remediation.

Check Point Head of Agentic Security Innovation Shahar Tal joins the Nexus Podcast to discuss research he and colleague Yarden Porat conducted that uncovered a dozen vulnerabilities in popular AI agent frameworks such as LangChain, LangGraph, CrewAI, AutoGen, Microsoft Agent Framework, and Google ADK. The vulnerabilities allow an attacker to exploit the inherent trust given to AI agents and can pave the way to remote code execution and other malicious outcomes.

Ellen Boehm, Senior Vice President Strategy and AI Innovation at Keyfactor, joins the Nexus Podcast to discuss post-quantum cryptography (PQC) readiness in critical infrastructure organizations. A recent Executive Order on PQC installed a December 2030 deadline for federal agencies to transition high-value systems and key generation to PQC. The EO also directs CISA, other federal sector risk management agencies to assist with road map development. 

In this episode, Ellen discusses readiness in this context. She also delves into how critical infrastructure organizations overseeing fleets of cyber-physical systems (CPS) assets transition those environments and avoid disruptions. Governance, budgeting, supply chain management, and the AI-driven threat landscape are also discussed. 

This episode was recorded during the Black Hat USA Conference.

John Laliberte, CEO of ClearVector, joins the Nexus Podcast in an episode recorded at Black Hat 2026 in Las Vegas. Laliberte discusses how artificial intelligence (AI) is accelerating the creation of so-called non-human identities, including autonomous identities created by AI agents. 

Laliberte covers the risks and controls that enterprises and critical infrastructure organizations must consider as AI adoption accelerates everywhere.

Jessica Ji, a Senior Research Analyst at Georgetown’s Center for Security and Emerging Technology and its CyberAI Project, joins the Nexus Podcast to discuss how frontier AI models such as Claude Mythos are changing cybersecurity for practitioners and policymakers alike. 

Jessica works closely with policymakers in the U.S. government. She discusses how they view AI models' offensive and defensive capabilities, the need for a long-term strategy on AI and cybersecurity, and the disparate incentives between private AI companies such as Anthropic and OpenAI and the government as these models are developed and deployed.

ICS Advisory Project founder Dan Ricci joins the Nexus Podcat to discuss how to turn operational technology (OT) and cyber-physical systems (CPS) visibility into actual risk reduction. Dan describes the need to distinguish between asset lists and actual asset inventories, what those differences are, and how to make the most of the information made available. Device data such as firmware versions, protocol identification, and more are vital to other aspects of the OT and CPS protection program, including exposure management and segmentation initiatives.

Dan wrote more on this topic in this article: “From Inventory to Insight: Turning OT Visibility into Concrete Risk Reduction.”

Krista Arndt, the Associate Chief Information Security Officer (CISO) at the St. Luke's University Health Network, a 15-hospital health system in Pennsylvania and New Jersey, joins the Nexus Podcast to discuss cybersecurity and resilience in a large hospital system. 

Krista and her team talk about the role of healthcare cybersecurity teams in ensuring patient safety, and some of the ongoing challenges in keeping medical devices and the healthcare network available and resilient to attack. 

Krista also discusses a microsegmentation project implemented through Elisity that helped remove blockers impeding innovation around robotic surgical systems.
