How It Works
We connect to your server via TLS and retrieve the SSL/TLS certificate chain. We then decode the certificate to extract the issuer, subject, validity period, signature algorithm, and supported TLS versions — all without storing any sensitive data.
Why SSL Matters for E-commerce
SSL is non-negotiable for e-commerce. Chrome marks all HTTP pages as 'Not Secure', which can reduce trust and conversions by up to 70%. Google also uses HTTPS as a ranking signal. An expired certificate will completely block users from accessing your store.
What We Check
Certificate validity (not expired/not yet valid), issuer authority (trusted CA or self-signed), remaining days until expiry, signature algorithm strength, TLS protocol version support (1.2/1.3), certificate chain completeness, and wildcard vs standard coverage.
Pro Tips for SSL Management
Set calendar reminders 30 days before expiry. Use Let's Encrypt for free auto-renewing certificates. Enable TLS 1.3 for best performance and security. Avoid self-signed certificates for production — they trigger browser warnings that kill conversions.
