About SSL Security Score

Calculates a comprehensive security score (0-100) for a server's SSL/TLS configuration. Weighs certificate strength, protocol support, cipher suite selection, and security features.

How to Use

1Enter the domain name and optional port number.
2Click "Calculate Score" to analyze the SSL/TLS configuration.
3Review the overall score and detailed breakdown by category.

Use Cases

•Security benchmarking to compare SSL configurations across servers
•Compliance verification against security standards and policies
•Improvement tracking to measure the impact of configuration changes

Frequently Asked Questions

The score is calculated by evaluating multiple factors: certificate strength (key size, signature algorithm), protocol support (TLS 1.3 bonus), cipher suite quality, and presence of security features like HSTS and OCSP stapling.

The biggest score impacts come from: weak or deprecated protocols (SSL 2.0/3.0, TLS 1.0), weak cipher suites (RC4, DES, 3DES), missing forward secrecy, and certificate issues (short key, weak signature).

Enable TLS 1.3 and 1.2 only, use strong cipher suites with forward secrecy, obtain certificates with 2048-bit or larger keys, enable OCSP stapling, and implement HSTS headers.

Tips & Best Practices

•Track security scores over time to measure improvement
•Focus on low-scoring categories for maximum improvement impact
•Use security scores for benchmarking against industry standards
•Set score targets and monitor progress toward security goals
