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:

From free observation to reviewable evidence
- Check an authorized asset. The free result names bounded machine-observable facts and its blind spots.
- Inspect the matching sample. See the remediation or ledger sections before deciding whether the paid artifact fits your work.
- Checkout only when delivery is ready. Billing, delivery, refunds, retention, and required scheduled jobs are rechecked before the first-party checkout hop redirects to Polar.
