Measure What Matters
Mark Overholser
SAINTCON 2025 · Day 2 · Main Track 1
In his SAINTCON talk, "Measure What Matters," Mark Overholser, a Technical Marketing Engineer and Threat Hunter at Corelight, delivers a foundational yet critical message for blue teams and Security Operations Centers (SOCs): the imperative of data-driven decision-making. Overholser argues that without robust and relevant metrics, security efforts are reduced to mere guesswork, making it impossible to accurately assess performance, justify investments, or communicate value to the broader business. The presentation serves as a guide for security professionals, particularly those early in their careers or building out security teams, on how to establish effective measurement practices.
