One of my most important learnings after more than two decades in cybersecurity is simple but fundamental: you cannot protect what you do not understand. This principle has proven true in every technological shift we have faced, from operating systems and network protocols to email systems, enterprise applications, hypervisors, cloud infrastructure, containers, serverless architectures, APIs, and identity platforms. Each time a new layer of technology emerged, it introduced not only new capabilities but also new assumptions, new trust boundaries, and new attack surfaces. Organizations that took the time to understand how these systems actually worked were able to secure them. Those that treated them as black boxes were forced into reactive defense, responding to compromises after the fact rather than preventing them by design.
