The BIG Questions
Can this domain be impersonated by email? Uncertain incomplete configuration
Can DNS itself be tampered with? Possible
Can this brand be convincingly faked? Likely
Is mail transport encryption enforced? Not Assessed
Is certificate issuance controlled? Yes
Does this domain publish AI agent instructions? No No llms.txt file detected — AI models have no structured instructions for this domain
Is AI crawling of our content controlled? No No robots.txt found — AI crawlers have unrestricted access
Has someone manipulated AI recommendations about us? No No indicators of AI recommendation manipulation found
Are there hidden AI prompts on our site? No No hidden prompt artifacts found in page source

Poisoning Indicators None Found No AI recommendation poisoning indicators detected
Hidden Prompt Artifacts None Found No hidden prompt artifacts detected
Priority Actions 4 total Achievable: Secure
Medium Add DMARC Aggregate Reporting

Add a rua= tag to receive aggregate DMARC reports. Without reporting, you cannot monitor authentication failures.

Medium Enable DNSSEC

DNSSEC is not enabled for this domain. DNSSEC provides cryptographic authentication of DNS responses, preventing cache poisoning and DNS spoofing attacks.

Low Add TLS-RPT Reporting

TLS-RPT (TLS Reporting) sends you reports about TLS connection failures when other servers try to deliver mail to your domain.

Low Deploy MTA-STS

MTA-STS enforces TLS encryption for inbound mail delivery, preventing downgrade attacks on your mail transport.

Appendix — Additional Resources

Full technical details including raw DNS records, DKIM public keys, IP/ASN mappings, resolver consensus evidence, and verification commands are available in the Engineer's DNS Intelligence Report.
