DNS Security & Trust Posture
Risk Level:

Analysis Confidence
MODERATE
Some DNS data may be stale or incomplete, limiting confidence. Resolver agreement and system maturity are adequate.

What Requires Attention
Critical
DNSSEC validation is failing
Recommended
Fix DNSSEC configuration or remove broken DS records
The BIG Questions
Can this domain be impersonated by email?
No
null MX indicates no-mail domain
Can DNS itself be tampered with?
Yes
DNSSEC validation is failing, DNS responses cannot be trusted
Can this brand be convincingly faked?
Likely
DMARC policy is not set to reject (RFC 7489 §6.3) — partial protection only
Is mail transport encryption enforced?
Unknown
Mail transport security could not be verified — the MTA-STS DNS lookup did not complete; a TLS-RPT record alone does not enforce TLS, so this is not evidence enforcement is absent. Re-run before concluding transport encryption is unenforced
Is certificate issuance controlled?
Unknown
CAA records could not be verified — the DNS lookup did not complete (transient resolver failure); re-run before concluding any certificate authority may issue
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

DNS Security
Can DNS itself be tampered with?
Yes
— DNSSEC validation is failing, DNS responses cannot be trusted
DNSSEC
Partial
DNSSEC configured (DNSKEY + DS records present) but validation failed — the chain of trust is broken (RFC 4033 §5: bogus is signaled via SERVFAIL / RCODE=2).

Priority Actions 2 total Achievable: Low Risk
Critical
Fix Broken DNSSEC
DNSSEC validation is failing for this domain. This can cause resolvers to reject all DNS responses, making your domain unreachable.
High
Add DMARC Reject for Null MX Domain
This domain publishes a Null MX record (RFC 7505) but lacks a DMARC reject policy. Without it, attackers can still spoof email from this domain. Complete the no-mail hardening with a strict DMARC reject policy.
