What Requires Attention
Recommended
Upgrade DMARC policy from quarantine to reject (p=reject) for maximum spoofing protection
Recommended
Add DMARC aggregate reporting (rua) for visibility into email authentication
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?
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?
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

Priority Actions 2 total Achievable: Secure
Medium
Add DMARC Aggregate Reporting
Add a rua= tag to receive aggregate DMARC reports. Without reporting, you cannot monitor authentication failures.
Medium
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.
