Most organizations rely on security metrics that measure what's easy to count rather than what truly matters. Ten fundamental but difficult-to-measure security metrics are proposed as 'Pareto metrics' that drive 80% of meaningful outcomes. These include: software and infrastructure reproducibility (percentage deployable via CI/CD or immutable infrastructure), SLSA-based software lifecycle security, time to fully rebuild the company after a destructive attack, OODA loop speed relative to attackers, blast radius index for role-based damage potential, systems stagnancy tracking, preventative maintenance budget as a percentage of operating budget, control pressure index measuring how deep attacks penetrate defense-in-depth stacks, and inventory triangulation accuracy. The core argument is that even the act of attempting to measure these metrics surfaces critical gaps and drives improvements. Boards and executives need to be educated to understand these nuanced metrics rather than organizations dumbing down reporting to what leadership already knows.
