DNS Security & Trust Posture
Risk Level:
Low Risk
7 protocols configured, 2 not configured
Analysis Confidence
MODERATE
Resolver agreement is inconsistent for some protocols, limiting confidence. Data currency and system maturity are adequate.

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 and validated, cryptographic chain of trust verified
Can this brand be convincingly faked?
No
DMARC reject policy enforced (RFC 7489 §6.3), BIMI brand verification active (BIMI Spec), and certificate issuance restricted by CAA (RFC 8659 §4) — all three brand-faking vectors addressed
Is mail transport encryption enforced?
Partially
TLS reporting is configured but no transport enforcement policy is active
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
