DNS Security & Trust Posture
Risk Level: Medium Risk
6 protocols configured, 2 not configured, 1 unavailable on provider
1 recommendation
Analysis Confidence
MODERATE
Resolver agreement is inconsistent for some protocols, limiting confidence. Data currency and system maturity are adequate.
Email Spoofing
Partial
Brand Impersonation
Not Set Up
DNS Tampering
Unsigned
Certificate Control
Configured
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 is monitor-only (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? Yes MTA-STS enforces TLS for all inbound mail delivery
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 MarkMonitor Inc.
Email Provider Microsoft 365
Web Hosting Unknown
DNS Hosting Microsoft Azure DNS

Technical Findings

Email Authentication
Can this domain be impersonated by email? Yes — DMARC is monitor-only (p=none)
SPF (Sender Policy) Configured
DMARC (Policy) Partial Policy: none Monitor Only
DKIM (Signatures) Configured
Mail Posture Moderately Protected
Mail Transport Security
Is mail transport encryption enforced? Yes — MTA-STS enforces TLS for all inbound mail delivery
MTA-STS Active Mode: enforce
DANE / TLSA Hosted Provider DANE not available — Microsoft 365 does not support inbound DANE/TLSA on its MX infrastructure
TLS-RPT (Reporting) Configured
Mail Transport 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 Managed DNS
Delegation Consistency 1 Issue
NS Fleet Health Healthy Diversity: Fair
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) 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 2 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.
