How to Measure a Company’s Cyber Risk with the Breach Susceptibility Indicator

SecurityScorecard's Breach Susceptibility Indicator (BSI) is a 100% data-driven metric that quantifies an organization’s potential breach risk—ranging from "Very Low" to "Very High"—by combining SecurityScorecard ratings, digital footprint size, and a hyperoptimized non-linear model trained and validated against real-world cyber insurance claims (including analysis by Marsh McLennan’s CRIC); it is intended to support underwriting, pricing accuracy, third-party risk assessment, and proactive loss prevention rather than provide prioritized remediation guidance.
