In today’s digital battlefield, prevention is no longer enough. Firewalls and endpoint protection might keep the doors locked, but attackers are slipping in through the windows. In this episode of Tech Talks Daily, I sit down with Brian Dye, CEO of Corelight, to explore how the cybersecurity game has changed and why network detection and response (NDR) has become the new frontline of digital defense.

Brian brings an extraordinary track record from senior roles at Symantec, McAfee, and Citrix, giving him a rare perspective on how cyber strategy has evolved from antivirus software to AI-driven network intelligence. As he explains, “The days of when things were nice and loud and easy to find have come and gone.” Attackers now live off the land, using legitimate IT tools like PowerShell to hide in plain sight, while generative AI accelerates the weaponization of new exploits in hours instead of weeks.

We discuss why Corelight’s open-source heritage gives it a unique edge in the GenAI era, how automation is reshaping response workflows, and what it really takes to achieve sub-15-second threat response. Brian also opens up about leadership lessons learned from his years in the industry, Corelight’s growth from startup to global scale, and the cultural principles that keep innovation alive through rapid expansion.

This conversation goes far beyond cybersecurity buzzwords. It is a candid look at the reality facing modern defenders, where data is readiness, visibility is power, and resilience is built one decision at a time. Whether you are a CISO, developer, or business leader, this episode offers a grounded, human perspective on the future of cyber defense and what it means to truly understand what went “bump in the night.”
