Analysis Confidence
MODERATE
Some DNS data may be stale or incomplete, limiting confidence. Resolver agreement and system maturity are adequate.
Email Spoofing

What Requires Attention
Recommended Move DMARC policy from 'none' to 'quarantine' or 'reject'
The BIG Questions
Can this domain be impersonated by email? Yes DMARC requests no enforcement (p=none)
Can DNS itself be tampered with? Possible DNSSEC is not deployed, DNS responses are not cryptographically verified
Can this brand be convincingly faked? Likely DMARC is monitor-only p=none (RFC 7489 §6.3) — spoofed mail is not blocked, brand faking is trivial
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

Technical Findings

Email Authentication
Can this domain be impersonated by email? Yes — DMARC requests no enforcement (p=none)
SPF (Sender Policy) Configured
DMARC (Policy) Partial Policy: none Monitor Only
DKIM (Signatures) Not Detected
Mail Posture Probable No-Mail Domain — Needs Formal Declaration
Mail Transport Security
Is mail transport encryption enforced? No — No MTA-STS or DANE — mail transport encryption is opportunistic only
MTA-STS Partial
DANE / TLSA Hosted Provider No MX records available — DANE check skipped
TLS-RPT (Reporting) Not Configured
Mail Transport Not Enforced Policy-assessed
DNS Security
Can DNS itself be tampered with? Possible — DNSSEC is not deployed, DNS responses are not cryptographically verified
DNSSEC Partial
DNSSEC not configured - DNS responses are unsigned
NS Delegation Healthy
Delegation Consistency 2 Issues
Brand & Certificate Controls
Can this brand be convincingly faked? Likely — DMARC is monitor-only p=none (RFC 7489 §6.3) — spoofed mail is not blocked, brand faking is trivial
Is certificate issuance controlled? Yes — CAA records restrict which certificate authorities may issue certificates
BIMI (Brand Logo) Configured
CAA (Certificate) Configured
AI Surface Scanner Scanned
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
LLM Context File Not Found No llms.txt file detected
AI Crawler Governance No robots.txt
Poisoning Indicators None Found No AI recommendation poisoning indicators detected
Hidden Prompt Artifacts None Found No hidden prompt artifacts detected
Public Exposure Clear No secrets detected in publicly accessible source
Priority Actions 4 total Achievable: Low Risk
High Upgrade DMARC from p=none

Your DMARC policy is monitor-only (p=none). Upgrade to p=quarantine or p=reject after reviewing reports to actively prevent spoofing.

Medium Enable DNSSEC

DNSSEC is not enabled for this domain. DNSSEC provides cryptographic authentication of DNS responses, preventing cache poisoning and DNS spoofing attacks.

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.
