SSL Config

Overview

SSL Config is an online SSL/TLS configuration checker and security diagnostic platform that helps server administrators detect and optimize SSL security configurations. SSL Config is not a certificate authority (CA)—it is a security assessment tool. Users enter a domain name, and the system automatically scans the server's SSL/TLS protocol support, certificate chain integrity, cipher suite configuration, HSTS deployment status, and other security indicators, providing a security rating from A+ to F.

SSL Config's positioning is similar to SSL Labs, but with a cleaner interface and faster scan speed. For website administrators who have just completed SSL deployment, SSL Config offers a convenient "one-click check" tool to quickly identify configuration issues and obtain optimization recommendations.

Key Strengths

• 10-Second Fast Scan: Enter a domain and the system completes a full-port scan within 10 seconds, quickly presenting the security rating and key detection results. Compared to SSL Labs requiring several minutes for deep analysis, SSL Config is better suited for quick verification scenarios.
• Comprehensive Security Checks: Covers 20+ security indicators including TLS 1.0/1.1/1.2/1.3 protocol support, certificate chain integrity, cipher suite strength, HSTS deployment, CSP policy, X-Frame-Options, and HTTP/2 support. Each scan generates a structured report highlighting security risks and optimization suggestions.
• Platform-Agnostic Recommendations: Whether using Apache, Nginx, IIS, Tomcat, or Caddy, SSL Config's optimization recommendations are platform-specific. Nginx users receive specific ssl_ciphers configuration advice, while Apache users get corresponding SSLCipherSuite directives. See CDN and SSL/TLS configuration best practices for general configuration steps.
• Completely Free with No Registration: All scan features are free with no account creation or login required. This zero-barrier approach is convenient for ad-hoc checks and quick diagnostics.

Product Ecosystem

Quick Scan

Default scan mode. Enter a domain to execute standard checks covering certificate validity, TLS protocol versions, cipher suites, HSTS status, and other core indicators. Results display as a color-coded security rating card: green (A/A+), yellow (B/C), red (D/F).

Deep Scan

Advanced detection mode for comprehensive certificate chain validation, OCSP stapling detection, CAA record checking, and DNS consistency verification. Deep scans take approximately 1-2 minutes, suitable for full acceptance testing after SSL deployment.

Configuration Reports

Each scan generates a detailed HTML report containing explanations, current status, and optimization recommendations for every detected item. Reports can be exported and saved for security compliance audit records. For organizations needing PCI DSS or other compliance requirements, these reports serve as SSL configuration compliance evidence.

Limitations

• Diagnostic Only, No Certificate Issuance: SSL Config cannot issue or sell SSL certificates. If scans detect certificate problems (expiration, incomplete chain), users must purchase or renew certificates separately. Scan reports suggest certificate types and CA recommendations, but users need to contact certificate vendors independently.
• Limited Brand Recognition: SSL Config's brand awareness in the SSL security diagnostic field is significantly lower than SSL Labs (Qualys), with fewer citations in community discussions and technical blogs. Users seeking authoritative scan results may prefer SSL Labs.
• Potential Data Lag: SSL Config's protocol version and browser compatibility database updates may lag 1-2 months behind the latest IETF standards and browser release schedules, potentially missing recognition of new TLS extensions or cipher suites.
• No API Interface: SSL Config currently offers no public API for CI/CD pipeline integration or batch scanning. For teams requiring automated periodic SSL checks, security log auditing basics provides alternative tool recommendations.

Use Cases

• Post-Deployment SSL Verification (★★★★★): Immediately after certificate installation, use SSL Config to verify configuration correctness and get a security rating within 10 seconds.
• Periodic Security Audits (★★★★☆): Schedule regular scans to ensure certificates haven't expired, protocol versions haven't been downgraded, and security policies remain active.
• Pre-Purchase Configuration Assessment (★★★★☆): Before buying new certificates, scan current configurations to understand which TLS versions and cipher suites the server supports, informing certificate selection.
• CI/CD Automation Integration (★☆☆☆☆): No API available—not suitable for automated integration. Use SSL Labs or other API-supported tools instead.

Pricing

All features are completely free with no registration required.

FAQ

• Can SSL Config sell me an SSL certificate? No. SSL Config is a diagnostic tool only. If reports detect certificate issues, they suggest the appropriate certificate type, but users must purchase through certificate vendors separately—see CDN and SSL/TLS configuration best practices.

• What does an A+ rating mean? A+ is SSL Config's highest security rating, indicating the server SSL configuration meets current best practices: TLS 1.2/1.3 enabled, weak cipher suites disabled, complete certificate chain configured, HSTS enabled, etc. A+ ratings typically satisfy PCI DSS and similar compliance requirements—see CDN and SSL/TLS configuration best practices.

• SSL Config vs SSL Labs: which is more accurate? SSL Labs (Qualys) offers deeper, more comprehensive scans and is the industry-recognized SSL testing standard. SSL Config's advantages are scan speed and interface simplicity. For formal security audits, SSL Labs results should be the final reference—see the website security checklist.

• Does SSL Config require server-side installation? No. SSL Config is a fully online tool—simply enter a domain name and scans execute externally over the internet. No server-side components are needed—see CDN and SSL/TLS configuration best practices.

• Can SSL Config reports be shared? Scan report pages have unique URLs that can be shared directly with team members. Reports can also be exported as HTML files for offline storage—see security log auditing basics.
