    Episode 18 - Live Fire Defense at Locked Shields

    In this episode, host Richard Bejtlich sits down with Corelight Senior Sales Engineers Adam Donadeo and Nico Roosenboom to unpack their firsthand experiences at Locked Shields, the world’s largest international live-fire cyber defense exercise. The conversation dives deep into the chaotic, real-world friction of defending a massive virtualized network alongside 4,000 global experts against aggressive red team waves. Adam and Nico share crucial insights on navigating vendor interoperability, the critical value of contextual log enrichment, and deploying specialized SCADA protocol packages to monitor critical infrastructure under intense pressure. For enterprise defenders, this episode highlights why a transparent, open-foundation network detection and response (NDR) strategy is essential for surviving real-world tactical friction and modern cyber threats.

    Episode 17 - Home Labs and Tinted Windows: Why Network Visibility Starts at Your Front Door

    In this episode, host Richard Bejtlich and guest Ricky Lin explore the practical—and often personal—side of network defense: monitoring the home network. Ricky shares how he uses Corelight and Zeek to track everything from his children's YouTube habits to the constant chatter of IoT devices like Tesla vehicles and smart appliances. They delve into the "tinted windows" analogy to explain why visibility into encrypted traffic is still possible through network metadata, even when the contents are hidden. By reflecting on 30 years of networking history—transitioning from the physical complexity of T1 lines to the dominance of Ethernet and IP—the conversation reveals why building with visibility in mind is the most essential, yet often overlooked, step in modern security architecture and troubleshooting.

    Episode 16 - Beyond the Black Box: Solving Data Overload with Agentic Triage

    In this episode, host Richard Bejtlich sits down with Dave Getman to discuss the evolution of Corelight Investigator and the paradigm shift from delivering raw sensor data to providing agentic triage. They explore how AI can synthesize millions of log lines into concise, actionable determinations—categorizing activity as malicious or benign—while maintaining transparency by "bringing the receipts" of raw evidence. Dave explains why the security pendulum is swinging back toward network detection to counter sophisticated EDR evasion and shares a roadmap for the future of auto-containment. By moving beyond the "black box" approach, this conversation reveals how AI serves as both a defender and a teacher, accelerating time-to-value for analysts and drastically reducing median dwell times on the network.

    Episode 15 - The Right Eyes: Mythos, and the Future of Vulnerability Discovery

    The emergence of advanced large language models like Anthropic's Mythos represents an epochal shift in cybersecurity, fundamentally altering how zero-day vulnerabilities are surfaced and remediated. In this episode, host Richard Bejtlich sits down with Corelight Co-founder Greg Bell to analyze the security implications of this AI-driven bug explosion, highlighting recent AI-assisted vulnerability discoveries across infrastructure mainstays like FreeBSD and Firefox. Together, they challenge the classic open-source maxim that "with enough eyes, all bugs are shallow," arguing instead that the arrival of the right automated eyes exposes an overwhelming pool of latent software flaws. Moving beyond the immediate operational chaos, Richard and Greg discuss the economics of declining token costs, the critical survival need for an assume-breach mentality, and how Corelight’s new agentic triage capabilities help defenders automate mind-numbing log review to achieve a resilient, human-led cybersecurity equilibrium.

    Episode 14 - Harvest Now, Decrypt Later: The Shift to Post-Quantum Cryptography

    The emergence of quantum computing has introduced a definitive expiration date for classical encryption, fueling a "harvest now, decrypt later" strategy among sophisticated nation-state actors. In this episode, Vince Stoffer joins Richard Bejtlich to demystify Post-Quantum Cryptography (PQC) and explain why organizations must move beyond a "set it and forget it" mentality regarding their encryption standards. They explore the critical role of Automated Cryptography Discovery and Inventory (ACDI) and how Network Detection and Response (NDR) provides a unique, passive vantage point to identify vulnerable cipher suites and track the real-time negotiation of quantum-resistant algorithms. By maintaining a clear picture of the cryptographic assets on the wire, defenders can proactively secure sensitive data against future decryption and meet the rising demands of modern regulatory standards.

    Episode 13 - Battle-Hardened Research: Navigating the Intersection of AI and Open Source

    Richard Bejtlich sits down with Ali Islam to pull back the curtain on how a security research lab functions within a modern security company. Moving beyond the "ivory tower" of academia, Ali explains why researchers must be battle-hardened by real-world threat actor techniques to remain effective in the field. The conversation dives into Corelight’s unique commitment to the open source community through the direct funding of Zeek and Suricata developers, ensuring that community-driven tools can scale to meet massive enterprise traffic demands. Finally, they explore the accelerating role of artificial intelligence in cybersecurity, weighing its ability to reduce analyst fatigue against the growing sophistication of AI-powered phishing and malware development.

    Episode 12 - The Agentic SOC: Upleveling Analysts with AI Knowledge Multipliers

    Richard Bejtlich sits down with Stan Kiefer, Corelight’s Senior Manager for Data Science, to discuss how AI serves as a vital "abstraction layer" and "knowledge multiplier" for security analysts. Stan explains that while AI can synthesize complex information, it remains untrustworthy without high-fidelity network data at its center to provide verifiable evidence. The episode explores the shift toward an "agentic ecosystem" and a tiered architecture where a central orchestrator manages specialized sub-agents to accelerate detection and investigation. Looking toward the future, Stan envisions a hybrid SOC environment where adaptive systems learn an analyst's specific workflows to automate routine tasks, acting as a professional companion that can cut the time needed to reach competency in half.

    Episode 11 - The AI Maturity Journey: Data, Agents, and the Shift from Craft to Art

    Richard Bejtlich talks with Vijit Nair, VP of Product at Corelight, about the evolving "AI Maturity Journey" for modern security teams. Vijit outlines a three-level spectrum of AI adoption, moving from basic human-driven assistance to automated swarms of agents, and eventually toward fully autonomous systems. They discuss why high-quality, unopinionated data remains the essential foundation for building trust in AI and how technologies like the Model Context Protocol (MCP) are turning human language into the primary interface for tool integration. The conversation explores the partnership between Corelight and CrowdStrike Charlotte AI as a real-world example of this connected ecosystem. Finally, Vijit and Richard reflect on how AI is "eating the craft" of security—automating away the mind-numbing manual tasks of a SOC—to allow analysts to focus on the "art" of judgment, creativity, and strategic defense.
