Security Scorecard is a platform that evaluates an organization's cybersecurity posture using externally observable data. It gathers information non-intrusively to analyze an external attack surface, identify vulnerabilities, and generate a security rating across multiple risk factor categories such as network security, patching cadence, and application security. The platform is used to assess an organization's own posture as well as that of third-party suppliers and partners without requiring their direct cooperation. It provides alerts on score changes, historical trend data, and maps findings to compliance frameworks. For remediation, it identifies specific issues contributing to the score, offers actionable improvement steps, and can be used to issue and manage vendor security questionnaires to correlate self-reported information with external evidence.
