Executive's DNS Intelligence Brief
DNS Security & Trust Posture
Risk Level:
Low Risk
8 protocols configured, 1 not configured

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?
Partly
SPF and DMARC are enforced at p=quarantine, 100% (RFC 7489 §6.3) — receivers accept failing mail and set it aside, so a spoofed message still reaches the mailbox in spam or junk rather than being refused
Can DNS itself be tampered with?
No
DNSSEC signed; a validating resolver confirmed the cryptographic chain of trust via the AD flag (RFC 4035 §3.2.3)
Can this brand be convincingly faked?
Likely
DMARC quarantine flags but does not reject spoofed mail (RFC 7489 §6.3), and no BIMI brand verification — lookalike domains display identically in inboxes; CAA restricts certificate issuance (RFC 8659 §4) but visual brand faking remains open
Is mail transport encryption enforced?
Yes
Both MTA-STS and DANE enforce encrypted 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?
Yes
robots.txt actively blocks AI crawlers from scraping site content
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.
