Risk consulting is the structured process of identifying, analyzing, prioritizing, and treating risks that could affect an organization’s operations, information, people, or goals. Cyber risk consultants review assets, controls, processes, likely scenarios, and business impact, then provide practical recommendations. The objective is not simply to produce a report; it is to help leaders decide what to address, accept, transfer, or monitor.
