Frequently Asked Questions
What is the SSL/TLS Security Scanner?
The SSL/TLS Security Scanner is a free tool that helps you analyze the HTTPS security configuration of your website. It checks your SSL certificate details, supported protocols (like TLS 1.2, 1.3), cipher strength, and whether important security headers like HSTS are properly enabled.
Why should I scan my website’s SSL/TLS setup?
A misconfigured SSL/TLS setup can leave your website vulnerable to attacks like POODLE, Heartbleed, or downgrade attacks. Regularly scanning your SSL/TLS settings ensures you’re using modern, secure encryption practices and keeping user data safe.
What does the SSL scan check?
- SSL/TLS protocol support (TLS 1.0–1.3)
- Certificate issuer, validity, and expiry
- Presence of HSTS (HTTP Strict Transport Security)
- Weak cipher suites detection
- Common SSL vulnerabilities (like ROBOT, Heartbleed, POODLE)
Is this SSL/TLS scan safe to use?
Yes! The tool only reads public SSL/TLS settings from your server. It does not modify, attack, or alter anything on your website. It simply analyzes publicly available SSL information, just like a web browser would.
How often should I scan my website?
It’s a good idea to scan your website:
- After issuing a new SSL certificate
- After server updates or configuration changes
- Every few months, to ensure you meet the latest security standards
Will this tool grade my SSL security?
Yes! Based on your SSL/TLS configuration, the scanner will assign a basic grade (A+, A, B, C, F) to give you a quick view of your website’s security status.
What should I do if my scan shows problems?
If the scan detects outdated protocols (like TLS 1.0), weak ciphers, or missing security headers, it’s recommended to:
- Update your server configuration to enforce stronger security
- Re-issue your SSL certificate if it's close to expiry
- Enable HTTP Strict Transport Security (HSTS) for added protection
Is this SSL scanner mobile-friendly?
Absolutely! The scanner is built with a responsive design to work smoothly across desktops, tablets, and smartphones — perfect for quick checks anytime, anywhere.
