What It Does
Built on Sounil Yu's Cyber Defense Matrix — a framework that maps what you have against what you need. Used by Protectia engineers in review sessions with your team.
Plot your security tools and capabilities across 5 asset classes and 5 NIST functions. See at a glance what’s covered and what isn’t.
Rate each cell from 1 to 5 based on real capability — not vendor promises. Track progress as your program matures.
Stop guessing where you’re exposed. The matrix reveals blind spots that slide decks and sales pitches won’t show you.
Security isn’t a solo effort. Invite your team, share assessments, and get everyone — technical or not — on the same page.
Export structured assessment data that’s safe to share with AI tools. No credentials, no architecture details — just the signal an LLM needs to help you prioritize.
Ecosystem
Every security tool covers different cells. See where the overlap is and where the gaps are — no vendor pitch required.
Cloud-native endpoint protection platform that combines next-gen antivirus, endpoint detection and response, and managed threat hunting.
Covers 5 of 25 cells
AI-Powered
An agentic assistant that reads your projects, finds gaps, and proposes changes — you stay in control.

Endorsements
Industry leaders on the Cyber Defense Matrix framework.
“Cybersecurity has become too complex — chaotic even. The Cyber Defense Matrix helps break through the noise, offering a clear understanding of how our assets relate to one another and reinforcing our ability to gain deeper structural and situational awareness.”

The Problem
Marketing lingo, made-up terminology, and endless vendor consolidation have made it nearly impossible to understand what a security tool actually does for your program. Brands merge, products rebrand, and capabilities get buried under layers of buzzwords.
Sounil Yu created the Cyber Defense Matrix as a way to cut through the noise — a simple 5×5 grid that maps security functions against asset classes. It started as a framework in a book. Protectia Cobertura turns that framework into an instrument Protectia engineers use with your team to see where your controls are, and where they are not.
Process
Set up a project for your organization and define what you’re assessing.
Walk through all 25 cells. Rate your actual maturity — not where you wish you were. Map the tools you have.
Review your coverage gaps, export reports, and prioritize what to fix based on real data.
Access is by invitation. Ask your Protectia engineer for a review session.
