What is an SSL certificate grade?
An SSL certificate grade summarizes whether a live HTTPS endpoint is safe for browsers and
operationally ready. HostRepute uses an A-F rubric that rewards trusted, matching, modern
certificates and flags issues that can cause browser warnings or renewal incidents.
Why check it?
Expired, mismatched, weak, or incomplete certificates cause browser warnings, scare away
visitors, and can hurt SEO trust signals. A grade makes the next fix obvious.
- Certificate has expired or is entering the renewal window
- Certificate does not match the domain name or SNI host
- Intermediate chain is missing or incomplete
- Weak signature algorithm, key size, protocol, or cipher metadata
- Different resolved IPs serving different certificates

HostRepute Certificate Monitoring
adds recurring HTTPS, TLS, STARTTLS, CAA, hostname, chain, fingerprint, and expiry checks
with alerts and private agent support.
What does an SSL certificate grade verify? +
HostRepute grades the live certificate using a pragmatic A-F rubric covering browser trust, hostname match, expiration risk, signature and key strength, CAA compatibility, resolved-IP consistency, and observed TLS metadata.
Is this the same as SSL Labs? +
No. The grade is SSL Labs-style, but optimized for fast free checks and monitoring. It does not run a full cipher-suite matrix scan.
Why does an SSL certificate expire? +
Certificates have fixed validity windows for security. They must be renewed before expiration to avoid browser warnings and trust issues.
Can SSL issues affect SEO? +
Yes. HTTPS is expected for modern websites, and certificate errors can hurt user trust, crawling, conversions, and page experience.
