We verify the certificate is current, not expired or self-signed, and has sufficient time before expiration.

Book a free consultationWhat do we analyze?
Your report covers 6 key areas of your domain's SSL/TLS configuration.
We validate the complete certificate chain up to a recognized Certificate Authority (CA).
We check TLS 1.3 and 1.2 support and detect deprecated protocols like TLS 1.0 and SSL.
We evaluate the negotiated cipher suite: forward secrecy, authenticated encryption (AEAD), and absence of weak algorithms.
We check the HSTS header (Strict-Transport-Security), max-age, includeSubDomains, and preload directive.
We analyze SANs (Subject Alternative Names), key type and size, and the certificate's SHA-256 fingerprint.
How does it work?
1
Enter your domain
Provide the domain you want to analyze along with your name and email to receive the report.
2
TLS connection
We connect to port 443 of your server to obtain the negotiated certificate, protocol, and cipher suite.
3
Full analysis
We evaluate 6 categories: validity, trust chain, protocol, cipher, HSTS, and certificate transparency.
4
Get your report
Within seconds you'll receive a PDF in your email with scores by category, findings, and prioritized recommendations.
Frequently Asked Questions
A professional SSL/TLS analysis evaluates 6 areas: certificate validity (expiry, self-signing), trust chain (recognized CA), TLS protocol (1.3/1.2 vs deprecated), cipher suite (forward secrecy, AEAD), HSTS headers, and transparency details (SANs, key size). IQ Source's free analyzer covers all these categories.
Yes, IQ Source's SSL/TLS analyzer is 100% free with no strings attached. Enter your domain, and you'll receive a complete PDF report with per-category scores and recommendations directly in your email.
A complete SSL/TLS analysis takes 10 to 30 seconds. IQ Source's analyzer establishes a real TLS connection with the server, evaluates the certificate, protocol, and headers, then sends the report to your email within a minute.
A professional SSL/TLS report includes an overall score (0-100), grades for each of the 6 categories, specific findings on certificate, protocol, cipher, and HSTS, and recommendations prioritized by urgency to improve the configuration.
Yes, an online SSL analyzer only makes a standard TLS connection to the server — the same one any web browser would make. IQ Source's analyzer transmits your information encrypted, only uses your email to send the report, and doesn't store analysis results.
