To verify

Couldn't be confirmed from public data, so excluded from the score. Checking them clarifies your posture; it doesn't guarantee a score change.

DKIM — digital signature on email

Indicative alignment

Best-practice mapping of public findings to common frameworks. Passive scanning tests public configuration only; it doesn't prove compliance or a violation.

Google & Yahoo sender rulesIncomplete evidence · 1 unverified
SPF, DKIM and DMARC are required for bulk senders to Gmail and Yahoo; missing them risks rejected or spam-foldered mail.
PCI DSS v4.01 observed gaps
TLS, certificate and browser-header protections relate to PCI DSS v4.0 requirements 4.2 and 6.4 for payment pages.
CSP — protection from script injection
NIS2 / vendor due diligence1 observed gaps
Vendor risk reviews under NIS2/DORA and cyber-insurance questionnaires check these public signals.
DNSSEC — signed DNS records
SOC 2 / ISO 27001 baseline1 observed gaps
Baseline external hygiene commonly expected in SOC 2 and ISO 27001 audits.
CSP — protection from script injection

Indicative alignment only, based on public configuration. It doesn't establish whether a framework applies to you, and it isn't legal advice, an audit or a certification.
