Theo H.

Security Researcher & Systems Thinker

Theo H. focuses on how security operations are evolving as data, automation, and AI reshape the way teams detect and respond to threats. With a background spanning security engineering and platform design, Theo has worked on building and integrating systems that connect telemetry, detection logic, and response workflows across modern security stacks. His work has centered on improving how security teams use data — not just collecting it, but turning it into actionable context for investigations and decisions. He writes about the structural challenges in today’s security operations models, including the limits of traditional SOC architectures, the gap between automation and real-world execution, and the emerging role of AI in augmenting human analysts. His perspective focuses on what is changing — and what isn’t — as organizations attempt to move from tool-driven operations to more adaptive, system-level approaches to security.
