Understanding the Security Status

✓ Green (Secure): A valid DMARC policy is active. The domain is protected because the policy is set to either quarantine or reject, effectively blocking or flagging unauthorized emails as mandated in the Payment Card Industry Data Security Standard (PCI DSS).
× Red (Inadequate): The domain fails to meet the "low bar" set by PCI DSS as the minimum requirement for protection. This occurs if the record is missing, duplicated, or if the policy is set to none (monitoring mode only), which does not stop spoofing attempts.

DMARC records are cached and refreshed periodically. The logic has been updated in line with RFC 9989, published in May 2026, and now uses DNS Tree Walk.
