SSL Config Scanner

Scan SSL configuration and get improvement recommendations

About SSL Configuration Scanning

SSL/TLS configuration scanning analyzes a server's security posture by examining supported protocols, cipher suites, certificate chain validity, and security features like HSTS and OCSP stapling. Our SSL Config Scanner provides a detailed report of your server's TLS configuration and offers prioritized recommendations to address vulnerabilities, disable deprecated protocols, and enforce modern security standards.

How to Use

Enter the domain name of the server you want to scan.
Specify the port number (default 443 for HTTPS).
Click Check to initiate the comprehensive SSL configuration scan.
Review the detailed report including protocol support, cipher suites, and security recommendations.

Use Cases

Security Hardening: Identify and remediate weak protocols, deprecated ciphers, and misconfigurations.
Pre-Deployment Validation: Verify TLS configuration before launching a new service or website.
Compliance Auditing: Ensure your server configuration meets PCI DSS, HIPAA, or internal security standards.
Continuous Monitoring: Regularly scan your infrastructure to catch configuration drift.

Frequently Asked Questions

An SSL config scan checks supported TLS protocol versions (1.0, 1.1, 1.2, 1.3), cipher suite preferences, certificate chain completeness, key exchange algorithms, and security features like HSTS and OCSP stapling.

It's recommended to scan your SSL configuration monthly, after any server configuration changes, and whenever new TLS vulnerabilities are disclosed. Regular scanning helps catch configuration drift and emerging threats.

A good SSL configuration should support TLS 1.2 and 1.3, disable SSL 2.0/3.0 and TLS 1.0/1.1, use strong AEAD ciphers, have a valid and complete certificate chain, enable HSTS, and support OCSP stapling.

Tips & Best Practices

•Run configuration scans after every TLS change to catch issues early
•Use the recommended configuration snippets to quickly fix identified issues
•Schedule regular scans to detect configuration drift before it becomes a security issue
•Compare scan results before and after hardening to demonstrate improvement
