The BIG Questions
Can this domain be impersonated by email?
Yes
DMARC is monitor-only (p=none)
Can DNS itself be tampered with?
No
DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked?
Likely
DMARC is monitor-only (p=none) — spoofed mail is not blocked
Is mail transport encryption enforced?
Yes
DANE/TLSA provides cryptographic transport verification
Is certificate issuance controlled?
Yes
CAA records restrict which certificate authorities may issue certificates
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?
Yes
robots.txt actively blocks AI crawlers from scraping site content
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

Priority Actions 4 total Achievable: Low Risk
High
Upgrade DMARC from p=none
Your DMARC policy is monitor-only (p=none). Upgrade to p=quarantine or p=reject after reviewing reports to actively prevent spoofing.
Medium
Add DMARC Aggregate Reporting
Add a rua= tag to receive aggregate DMARC reports. Without reporting, you cannot monitor authentication failures.
Low
Add TLS-RPT Reporting
Your domain has DNSSEC + DANE — the strongest email transport security available. 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.
