quantrr

Overview

Quantify and Report (Technology) Risk: A streamlined tool designed to make it easier to quantify risk using expert estimation. Given expert estimates for loss frequency and magnitude, generate a report that forecasts losses by risk and in aggregate.

First presented as a demo in my 2024 SIRAcon talk, “UnFAIR: Simplifying and Expanding Technology Risk Quantification.”

A rendered version of the standalone sample report is available here.
