Calculate risk scores using a 5×5 likelihood × impact matrix
Assess risks using the industry-standard 5×5 risk matrix methodology. Rate likelihood (Rare to Almost Certain) and impact (Negligible to Catastrophic), apply control effectiveness percentage, and calculate both inherent and residual risk scores. Includes a visual 5×5 matrix reference, risk treatment recommendations, and support for 8 risk categories.
