Free bounded evidence check

Check email anti-phishing evidence for PCI DSS requirement 5.4.1

Requirement 5.4.1 addresses mechanisms that protect personnel against phishing. This bounded DNS check inspects discoverable SPF, DKIM, and DMARC signals and names what still requires provider or assessor confirmation. It does not determine compliance or discover every DKIM selector. Check your own sending domain free:

  • No account or card details
  • Raw results are not retained in a result database
  • Observation stays separate from human judgment
  • Every blind spot remains visible in the result

A visible current, not a score

Each observation keeps its source and its limit.

This specimen is synthetic and sends no request. A real check replaces it with observations from the request snapshot.
