Frequently Asked Questions

Common questions about the Risk Matrix Calculator

A risk matrix is a visual tool that helps organizations assess and prioritize risks by plotting likelihood against impact on a grid. Each cell represents a risk level (Low, Medium, High, Critical) based on the combination of how likely a risk is to occur and how severe its consequences would be. This tool supports multiple industry-standard frameworks including NIST.
