Enterprise Risk in Acuna provides a structured risk register where each risk is scored on likelihood and impact across configurable dimensions (financial, operational, reputational, regulatory). Risks are linked to controls, assets, processes, and owners. The module supports risk treatment plans (mitigate, accept, transfer, avoid) with action tracking, residual risk recalculation after control implementation, and heat-map visualisation for management reporting. Risk data integrates with other modules: a high-risk supplier in Supplier Shield or a failed control in Implement surfaces as a risk event automatically.
