What it checks
Expiry (staged 30/14/7/1-day severities), expired certs, hostname mismatch, untrusted/self-signed chains, missing intermediates, obsolete protocols, a legacy TLS 1.0/1.1 acceptance probe, weak ciphers, weak keys, and SHA-1 signatures. Every finding ships with its remediation, deduplicates across scans, and auto-resolves when fixed.
