Methodology credits
- Cyber Defense Matrix 2.0 — extending Sounil Yu's original Cyber Defense Matrix and NIST CSF 2.0 from a 5×5 grid to 7×9, adding an ANTICIPATE function and four new asset rows. Read the full methodology →
- You Already Own the Fix — the coined insight that most organizations use 30–50% of their existing security tool capabilities, and that comparing CAN vs. IS reveals gaps closable without new spend. Read the full argument →
- SecurityStack vendor database — 27 years of field judgment encoded as capability mappings. Competitors can copy the framework; they cannot copy the data.

Frequently asked questions
Who built SecurityStack?
SecurityStack is built by Arien Seghetti, a 27-year cybersecurity practitioner with enterprise, federal, and commercial experience across WWT, Axonius, Cymulate, Lockheed Martin, Iron Bow, and Sirius. He is a USAF and Army veteran.
Why is SecurityStack different from a consulting engagement?
A typical security tools rationalization engagement runs $50K–$150K and takes six to twelve weeks. SecurityStack automates that work — inventory, coverage analysis, gap identification, 'You Already Own the Fix' recommendations — and delivers it in 30 to 60 minutes.
How do I know the vendor database is accurate?
The vendor database encodes 27 years of field experience. Every capability mapping reflects hands-on deployment and evaluation, not marketing material. Where a product's claimed capability does not match field reality, the database reflects field reality. Ongoing expansion is underway to reach ~191 vendors and ~366 products.
