Zscaler Risk360 quantifies risk by computing a risk score that is based on the number of remediations needed in comparison to the industry peer average. This approach allows organizations to understand their relative security posture by evaluating how many issues require remediation and benchmarking that against peers in the industry. This methodology enables prioritized risk management and provides context around the urgency and scale of remediation activities necessary to reduce risk.
Unlike simply counting risk events or focusing on time to mitigate, Risk360 uses this comparative remediation-based scoring to give a comprehensive view of risk. It does not compute separate scores for each of the four breach stages but rather aggregates remediation efforts and benchmarks them to industry standards.
This is confirmed by the study guide's explanation of Risk360's scoring method, highlighting the use of remediation counts compared to peers as the basis for risk scoring.
