The Nexus podcast features conversations with security leaders, researchers, and experts sharing their expertise on cyber-physical systems security.
Tal Kollender, CEO and founder of Remedio, 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.

Nexus Podcast: Tal Kollender on the Age of Automated Security Exposure Remediation
Check Point Head of Agentic Security Innovation Shahar Tal joins the Nexus Podcast to discuss research he and researcher Yarden Porat presented at Black Hat on vulnerabilities in popular AI agent frameworks, including LangChain, LangGraph, CrewAI, AutoGen, Microsoft Agent Framework, and Google ADK. The vulnerabilities are an indication that these frameworks require additional scrutiny from a security perspective given the trust AI agents are given to execute tasks.
