DNS Security & Trust Posture
Risk Level:
Medium Risk
4 protocols configured, 4 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.

What Requires Attention
Recommended
Enable DMARC aggregate reporting (rua) for authentication visibility
The BIG Questions
Can this domain be impersonated by email?
Partially
DMARC quarantine at limited percentage
Can DNS itself be tampered with?
No
DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked?
Likely
DMARC quarantine flags but does not reject spoofed mail (RFC 7489 §6.3) — no BIMI or CAA (RFC 8659) reinforcement leaves brand impersonation largely unaddressed
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
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

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
Increase DMARC Coverage
Your DMARC policy only applies to 40% of mail. Increase pct to 100 for full protection.
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.
