Why each item matters
- Valid TLS certificate · methodology →
Every modern browser will block or warn on an invalid certificate. An expired or self-signed cert breaks the site for ordinary visitors.
- No exposed sensitive paths · methodology →
/.git, /.env, exposed /admin, or readable wp-config.php means credentials and source code are leaking. This is a vulnerability, not a polish issue.
- DMARC published · methodology →
Any DMARC policy (even p=none) shows the operator has thought about email spoofing. The bar cares about presence, not enforcement.
- SPF record present · methodology →
Without SPF, anyone can spoof mail from this domain. Required for any site whose domain is also used for email.
- No WordPress user enumeration · methodology →
When WordPress, the REST API leaking usernames hands attackers half of every credential pair. Strict pass — n/a on non-WP.
