The BIG Questions
Can this domain be impersonated by email?
Uncertain
incomplete configuration
Can DNS itself be tampered with?
No
DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked?
Partially
DMARC policy is not set to reject — partial protection only
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
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

DNS Security
Can DNS itself be tampered with?
No
— DNSSEC signed and validated, cryptographic chain of trust verified
DNSSEC
Signed & Validated
DNSSEC configured (DNSKEY + DS records present) but AD flag not set — resolver did not confirm chain of trust validation (RFC 4035 §3.2.3). This may indicate a broken chain or a non-validating resolver path.

Is certificate issuance controlled?
Yes
— CAA records restrict which certificate authorities may issue certificates

Priority Actions 3 total Achievable: Secure
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
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.
