Meridian Resilience
Threat modeling that small teams actually finish
Start with the applications your business can't live without, map their data flows, and record threats with owners and due dates — no security degree required.
How it works
- Apps ranked by criticality, open threats and how many systems rely on them.
- A data-flow diagram that matches your dependency map.
- Six guided STRIDE questions per app or connection, plus one-click common threats.
- Each threat gets a 5×5 score, status, owner, due date and fix.
Shared apps, different angles
- Each department rates a shared app for itself.
- The overall rating is the highest, and big disagreements are flagged.
Frequently asked questions
What is threat modeling?
A structured way to ask what could go wrong with a system, how bad it would be, and what you will do about it. Meridian guides you with six short questions per application or data flow.
What is STRIDE?
A checklist of six threat types: spoofing, tampering, repudiation, information disclosure, denial of service and elevation of privilege.
Why link threat modeling to a BIA?
Your BIA tells you which apps matter most. Meridian ranks apps by criticality and reliance so you model the crown jewels first.
Does AI change my scores?
No. AI guidance only suggests threats and gaps; nothing is added until you accept it, and BIA scores are never changed.
