DNS Security & Trust Posture
Risk Level:
Low Risk
5 protocols configured, 3 not configured, 1 unavailable on provider
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
SPF and DMARC reject policy enforced
Can DNS itself be tampered with?
Possible
DNSSEC is not deployed, DNS responses are not cryptographically 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?
No
No MTA-STS or DANE — mail transport encryption is opportunistic only
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
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

Priority Actions 3 total Achievable: Secure
Medium
Enable DNSSEC
DNSSEC is not enabled for this domain. DNSSEC provides cryptographic authentication of DNS responses, preventing cache poisoning and DNS spoofing attacks.
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.
