DNS Security & Trust Posture
Risk Level:
Low Risk
8 protocols configured, 1 not configured
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
Upgrade DMARC policy from quarantine to reject (p=reject) for maximum spoofing protection
The BIG Questions
Can this domain be impersonated by email?
Unlikely
SPF and DMARC quarantine policy enforced
Can DNS itself be tampered with?
No
DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked?
Unlikely
DMARC quarantine enforced (RFC 7489 §6.3) with BIMI brand verification (VMC-validated logo in inboxes) and CAA certificate restriction (RFC 8659 §4) — all three brand-faking vectors addressed; upgrade to p=reject to block spoofed mail outright instead of flagging
Is mail transport encryption enforced?
Yes
MTA-STS enforces TLS for all inbound mail delivery
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

Upgrade DMARC to Reject
Your DMARC policy is set to quarantine. Upgrade to p=reject for maximum protection — reject instructs receivers to discard spoofed mail entirely rather than quarantining it.
