DNS Security & Trust Posture
Risk Level: Medium Risk
7 protocols configured, 2 not configured
1 recommendation
Email Spoofing
Partial
Brand Impersonation
Not Set Up
DNS Tampering
Protected
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? No DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked? Likely DMARC is monitor-only (p=none) — spoofed mail is not blocked
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? No No llms.txt file detected — AI models have no structured instructions for 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? 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 — DANE/TLSA provides cryptographic transport verification
MTA-STS Partial
DANE / TLSA Active
TLS-RPT (Reporting) Configured
Mail Transport Enforced Policy-assessed
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
Brand & Certificate Controls
Can this brand be convincingly faked? Likely — DMARC is monitor-only (p=none) — spoofed mail is not blocked
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 — 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 Not Found No llms.txt file detected
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.

Low Deploy MTA-STS

MTA-STS enforces TLS encryption for inbound mail delivery, preventing downgrade attacks on your mail transport.
