The BIG Questions
Can this domain be impersonated by email?
No
null MX indicates no-mail domain
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), but no BIMI brand verification and no CAA certificate restriction (RFC 8659) — visual impersonation via lookalike domains and unrestricted certificate issuance remain open vectors
Is mail transport encryption enforced?
No
No MTA-STS or DANE — mail transport encryption is opportunistic only
Is certificate issuance controlled?
No
No CAA records — any certificate authority may issue certificates for this domain
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

Priority Actions 2 total Achievable: Low Risk
High
Harden SPF for Null MX Domain
This domain publishes a Null MX record (RFC 7505) declaring it does not accept email. Complete the no-mail hardening by adding a strict SPF record that explicitly denies all senders.
Low
Add CAA Records
CAA records specify which Certificate Authorities may issue certificates for your domain, reducing the risk of unauthorized certificate issuance.
