DNS Security & Trust Posture
Risk Level:
High Risk
4 protocols configured, 5 not configured
2 recommendations
Analysis Confidence
MODERATE
Resolver agreement is inconsistent for some protocols, limiting confidence. Data currency and system maturity are adequate.

What Requires Attention
Recommended
Publish an SPF record to authorize legitimate mail senders
Recommended
Add DMARC aggregate reporting (rua) for visibility into email authentication
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

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 5 total Achievable: Moderate Risk
Critical
Publish SPF Record
Add an SPF record to authorize mail servers for this domain.
Medium
Add DMARC Aggregate Reporting
Add a rua= tag to receive aggregate DMARC reports. Without reporting, you cannot monitor authentication failures.
Low
Add BIMI Record
Your domain has DMARC reject — you qualify for BIMI, which displays your brand logo in receiving email clients that support it (Gmail, Apple Mail, Yahoo).
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.
