DNS Security & Trust Posture
Risk Level: Low Risk
4 protocols configured, 5 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
Unsigned
Certificate Control
Configured
What Requires Attention
Recommended Add DMARC aggregate reporting (rua) for visibility into email authentication
The BIG Questions
Can this domain be impersonated by email? No SPF and DMARC reject policy enforced
Can DNS itself be tampered with? Possible DNSSEC is not deployed, DNS responses are not cryptographically 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? 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
Domain Overview
Registrar Unknown
Email Provider Self-hosted
Web Hosting Unknown
DNS Hosting Unknown

Technical Findings

Email Authentication
Can this domain be impersonated by email? No — SPF and DMARC reject policy enforced
SPF (Sender Policy) Configured
DMARC (Policy) Configured Policy: reject
DKIM (Signatures) Not Detected
Mail Posture Strongly Protected
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 Not Enforced 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: Fair
Brand & Certificate Controls
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 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 5 total Achievable: Secure
Medium Add DMARC Aggregate Reporting

Add a rua= tag to receive aggregate DMARC reports. Without reporting, you cannot monitor authentication failures.

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 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.
