The BIG Questions
Can this domain be impersonated by email?
Partially
DMARC present but no SPF
Can DNS itself be tampered with?
No
DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked?
Possible
DMARC reject policy blocks email spoofing (RFC 7489 §6.3) and CAA restricts certificate issuance (RFC 8659 §4), but no BIMI brand verification — lookalike domains display identically in inboxes without visual proof of authenticity
Is mail transport encryption enforced?
No
No MTA-STS or DANE — mail transport encryption is opportunistic only
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?
No
robots.txt present but does not block AI crawlers — content may be freely scraped
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

Lock Down SPF for No-Mail Domain
This domain has no MX records and appears to be a website-only domain. Publishing a strict SPF record explicitly declares that no servers are authorized to send email, preventing attackers from spoofing your domain.
