Acuna supports four KPI data source types. Manual entry is for metrics from outside the platform (pen test scores, survey results). Computed KPIs calculate automatically from live compliance data using either a predefined metric library (grouped by Compliance, Operations, Risk, Controls, General, and Assure categories), a custom query builder with filters and operators, or a control-sourced effectiveness/execution feed. Connectors pull values from integrated external services. External API/webhook receives inbound values from systems that push data to Acuna. Per-item compliance thresholds with colour-coded progress bars are available for computed sources.
