Engineer
DNS Security & Trust Posture
Risk Level: High Risk
3 protocols configured, 6 not configured
2 recommendations
Analysis Confidence
MODERATE
Resolver agreement is inconsistent for some protocols, limiting confidence. Data currency and system maturity are adequate.
Email Spoofing
Vulnerable
Brand Impersonation
Not Set Up
DNS Tampering
Unsigned
Certificate Control
Configured
What Requires Attention
Recommended SPF uses ?all (neutral) — consider ~all or -all for stronger policy
Recommended Publish a DMARC record starting with p=none and rua reporting
The BIG Questions
Can this domain be impersonated by email? Likely SPF alone cannot prevent spoofing
Can DNS itself be tampered with? Possible DNSSEC is not deployed, DNS responses are not cryptographically 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

Technical Findings

Email Authentication
Can this domain be impersonated by email? Likely — SPF alone cannot prevent spoofing
SPF (Sender Policy) Partial
DMARC (Policy) Missing
DKIM (Signatures) Not Detected
Mail Posture Limited Protection
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 DANE/TLSA records found (checked 2 MX hosts)
TLS-RPT (Reporting) Not Configured
Mail Transport Verified Policy-assessed 2 probes
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 1 Issue
NS Fleet Health Healthy Diversity: Good
Brand & Certificate Controls
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 certificate issuance controlled? Yes — CAA records restrict which certificate authorities may issue certificates
BIMI (Brand Logo) Not 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 5 total Achievable: Moderate Risk
Critical Publish DMARC Record

Add a DMARC record to protect your domain against email spoofing and receive authentication reports.

High Upgrade SPF from ?all

Your SPF record uses ?all (neutral) which provides no protection. Upgrade to ~all (soft fail) for proper SPF enforcement.

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.
