The SecurityStack Methodology
Two ideas make SecurityStack possible. The Cyber Defense Matrix 2.0 — a 7×9 visual framework that extends Sounil Yu's original Cyber Defense Matrix and NIST CSF 2.0 with an ANTICIPATE function and four new asset rows (Cloud, OT/IoT, AI/ML, Supply Chain). And You Already Own the Fix — the observation that most organizations use 30–50% of their existing security tool capabilities, meaning the fastest ROI comes from what you already own.
