Some DNS data may be stale or incomplete, limiting confidence. Resolver agreement and system maturity are adequate.

What Requires Attention
Critical
No SPF and no DMARC — domain is completely unprotected against email spoofing. Both protocols are RFC-recommended (not mandatory), but their absence leaves the domain open to impersonation (CVE-2024-7208, CVE-2024-49040)
Recommended
Publish an SPF record to authorize legitimate mail senders
Recommended
Publish a DMARC record starting with p=none and rua reporting
The BIG Questions
Can this domain be impersonated by email?
Yes
no SPF or DMARC protection
Can DNS itself be tampered with?
No
DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked?
Yes
No DMARC policy (RFC 7489) — attackers can send email appearing to be from this domain with no sender-authentication barrier
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.

Priority Actions 4 total Achievable: Moderate Risk
Critical
Publish DMARC Record
Add a DMARC record to protect your domain against email spoofing and receive authentication reports.
Critical
Publish SPF Record
Add an SPF record to authorize mail servers for this domain.
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.
