Engineer
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 SPF and DMARC reject policy enforced
Can DNS itself be tampered with? No DNSSEC signed and validated, cryptographic chain of trust verified
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
Domain Overview

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 6 MX hosts)
TLS-RPT (Reporting) Not Configured
Mail Transport Not 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 2 Issues
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), 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 5 total Achievable: Secure
Medium Upgrade From Legacy DNSSEC Algorithm

This domain uses RSA/SHA-1 (algorithm 5 or 7) which is NOT RECOMMENDED per RFC 8624. While still operational, plan migration to ECDSAP256SHA256 (algorithm 13) or Ed25519 (algorithm 15) for improved security and smaller signatures.

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 CAA Records

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

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.
