Executive's DNS Intelligence Brief

Board-level domain security assessment — example.com

17 Aug 2026, 20:38 UTC · 9.6s · SHA-3-512: 81a7✱✱✱✱ Verify ·Archived
Golden-fixture baseline domain. This domain is part of the golden-fixture corpus: its recorded scan snapshot is the tool's regression baseline. A scan of it reproducing the snapshot is the baseline returning its own value — expected agreement, not independent validation.
DNS Security & Trust Posture
Risk Level: Low Risk
4 protocols configured, 5 not configured
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
Open
What Requires Attention
No urgent actions detected. Domain security posture is well-maintained.
The BIG Questions
Can this domain be impersonated by email? No null MX indicates no-mail domain
Can DNS itself be tampered with? No DNSSEC signed; a validating resolver confirmed the cryptographic chain of trust via the AD flag (RFC 4035 §3.2.3)
Can this brand be convincingly faked? Possible DMARC reject policy blocks email spoofing (RFC 7489 §6.3), but no BIMI brand verification and no CAA certificate restriction (RFC 8659) — visual impersonation via lookalike domains and unrestricted certificate issuance remain open vectors
Is mail transport encryption enforced? No No MTA-STS or DANE — mail transport encryption is opportunistic only
Is certificate issuance controlled? No No CAA records — any certificate authority may issue certificates for this domain
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? No — null MX indicates no-mail domain
SPF (Sender Policy) Configured
DMARC (Policy) Configured Policy: reject
DKIM (Signatures) Configured
Mail Posture No-Mail Domain — Fully Hardened
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 valid MX hosts — DANE check skipped
TLS-RPT (Reporting) Not Configured
Mail Transport Not Enforced Policy-assessed
DNS Security
Can DNS itself be tampered with? No — DNSSEC signed; a validating resolver confirmed the cryptographic chain of trust via the AD flag (RFC 4035 §3.2.3)
DNSSEC Signed & Validated
DNSSEC fully configured and validated — AD (Authenticated Data) flag set by validating resolvers 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 4 keys, 0 sigs
Brand & Certificate Controls
Can this brand be convincingly faked? Possible — DMARC reject policy blocks email spoofing (RFC 7489 §6.3), but no BIMI brand verification and no CAA certificate restriction (RFC 8659) — visual impersonation via lookalike domains and unrestricted certificate issuance remain open vectors
Is certificate issuance controlled? No — No CAA records — any certificate authority may issue certificates for this domain
BIMI (Brand Logo) Not Configured
CAA (Certificate) Open Any certificate authority may issue certificates
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 1 total Achievable: Hardened
Low Add CAA Records

CAA records specify which Certificate Authorities may issue certificates for your domain, reducing the risk of unauthorized certificate issuance.
