Your single biggest risk is that you don’t know how much risk you’re exposed to. Cyber risk quantification (CRQ) involves modeling risk scenarios and financially quantifying their business impact. It gives security professionals the means to explicitly assess cyber risk, and it enables the business to prioritize cost-effective mitigations. Yet many organizations find CRQ challenging because it represents a profound shift from today’s common cyber risk practices. This report helps security and risk (S&R) leaders build the business case for CRQ by using Forrester’s Total Economic Impact™ (TEI) model to conceptualize CRQ’s business value and plan successful implementations.
