DNS Security & Trust Posture
Risk Level:
Low Risk
6 protocols configured, 2 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?
No
DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked?
Possible
DMARC reject policy blocks email spoofing (RFC 7489 §6.3), but no BIMI brand verification and no CAA certificate restriction (RFC 8659) — visual impersonation via lookalike domains and unrestricted certificate issuance remain open vectors
Is mail transport encryption enforced?
Yes
MTA-STS enforces TLS for all inbound mail delivery
Is certificate issuance controlled?
No
No CAA records — any certificate authority may issue certificates for this domain
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
Low
Add BIMI Record
Your domain has DMARC reject — you qualify for BIMI, which displays your brand logo in receiving email clients that support it (Gmail, Apple Mail, Yahoo).
Low
Add CAA Records
CAA records specify which Certificate Authorities may issue certificates for your domain, reducing the risk of unauthorized certificate issuance.
