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.

The Cyber Defense Matrix

See Your Entire Security Posture at a Glance

Our CDM 2.0 matrix maps every tool you own across 7 security functions and 9 asset classes — 63 cells of coverage visibility. Instantly see where you’re covered, where the gaps are, and where tools overlap.
