DNS Security & Trust Posture
Risk Level: Low Risk
6 protocols configured, 3 not configured
1 recommendation
Analysis Confidence
MODERATE
Resolver agreement is inconsistent for some protocols, limiting confidence. Data currency and system maturity are adequate.
Email Spoofing
Protected
Brand Impersonation
Not Set Up
DNS Tampering
Protected
Certificate Control
Configured
What Requires Attention
Recommended Upgrade DMARC policy from quarantine to reject (p=reject) for maximum spoofing protection
The BIG Questions
Can this domain be impersonated by email? Unlikely SPF and DMARC quarantine policy enforced
Can DNS itself be tampered with? No DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked? Likely DMARC quarantine flags but does not reject spoofed mail (RFC 7489 §6.3), and no BIMI brand verification — lookalike domains display identically in inboxes; CAA restricts certificate issuance (RFC 8659 §4) but visual brand faking remains open
Is mail transport encryption enforced? Yes DANE/TLSA provides cryptographic transport verification
Is certificate issuance controlled? Yes CAA records restrict which certificate authorities may issue certificates
Does this domain publish AI agent instructions? Yes llms.txt and llms-full.txt published — AI models receive structured context about 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

Technical Findings

Email Authentication
Can this domain be impersonated by email? Unlikely — SPF and DMARC quarantine policy enforced
SPF (Sender Policy) Configured
DMARC (Policy) Configured Policy: quarantine
DKIM (Signatures) Not Detected
Mail Posture Moderately Protected
Mail Transport Security
Is mail transport encryption enforced? Yes — DANE/TLSA provides cryptographic transport verification
MTA-STS Partial
DANE / TLSA Active
TLS-RPT (Reporting) Not Configured
Mail Transport Enforced Policy-assessed 2 probes
DNS Security
Can DNS itself be tampered with? No — DNSSEC signed and validated, cryptographic chain of trust verified
DNSSEC Signed & Validated
DNSSEC fully configured and validated — AD (Authenticated Data) flag set by resolver 8.8.8.8 confirming cryptographic chain of trust from root to zone (RFC 4035 §3.2.3)
NS Delegation Healthy Managed DNS
Delegation Consistency 1 Issue
NS Fleet Health Healthy Diversity: Fair
DNSSEC Operations 1 Issue 2 keys, 0 sigs
Brand & Certificate Controls
Can this brand be convincingly faked? Likely — DMARC quarantine flags but does not reject spoofed mail (RFC 7489 §6.3), and no BIMI brand verification — lookalike domains display identically in inboxes; CAA restricts certificate issuance (RFC 8659 §4) but visual brand faking remains open
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 Governance Active
Does this domain publish AI agent instructions? Yes — llms.txt and llms-full.txt published — AI models receive structured context about 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
LLM Context File llms.txt Found Domain provides structured context for AI models Extended
AI Crawler Governance Not Blocking No AI crawler restrictions found in 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 3 total Achievable: Secure
Medium Upgrade DMARC to Reject

Your DMARC policy is set to quarantine. Upgrade to p=reject for maximum protection — reject instructs receivers to discard spoofed mail entirely rather than quarantining it.

Low Add TLS-RPT Reporting

Your domain has DNSSEC + DANE — the strongest email transport security available. 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.
