Summary: Security ratings are continuous, automated assessments of an organization’s cybersecurity on a scale (typically 0-900 or A-F), based on publicly visible indicators: open ports, SSL configuration, DNS records, dark web entries, and compromised systems. Providers such as BitSight, SecurityScorecard, and Riskrecon are used for vendor risk assessments, cyber insurance, and executive reporting.
