What Is a Website Trust Score and How Is It Calculated?
Understanding website trust scores and how to improve yours.
A website trust score is a numerical representation of a website's security posture. At SAB Security, we calculate it by analyzing multiple factors through passive observation.
How We Calculate the Score
Our trust score (0-100) is a weighted combination of: - **Security Headers (30%)**: Correct implementation of CSP, HSTS, X-Frame-Options, and more - **HTTPS & TLS (35%)**: HTTPS availability, certificate validity, redirect configuration - **DNS Records (25%)**: SPF, DKIM, and DMARC email protection - **Configuration Files (10%)**: robots.txt and security.txt presence and quality
What Your Score Means
- <strong>90-100 (A+)</strong>: Excellent security posture
- <strong>80-89 (A)</strong>: Strong security with minor improvements possible
- <strong>70-79 (B)</strong>: Good foundation, room for improvement
- <strong>60-69 (C)</strong>: Adequate but needs attention
- <strong>40-59 (D)</strong>: Significant issues present
- <strong>0-39 (F)</strong>: Critical problems requiring immediate action
