In this episode of Corelight Defenders, I’m joined by Bernard Brantley, Chief Information Security Officer at Corelight, as we delve into the concept of the enterprise nervous system. Bernard shares insights from his extensive experience in network analysis, explaining how organizations can leverage their network traffic data to enhance security and drive business outcomes. We discuss the importance of understanding the interdependencies between assets, processes, and goals, and how security teams can position themselves as integral to business success rather than just risk mitigators.

The new year brings renewed energy, refreshed goals, and sharper priorities. But at the same time, clarity can be hard to find as AI changes how work gets done, expectations rise, and cyber risk grows. As 2026 begins, several major shifts are already shaping how security teams operate, collaborate, and find satisfaction in their work.
