DNS Security & Trust Posture
Risk Level: Medium Risk
5 protocols configured, 4 not configured
1 recommendation
Analysis Confidence
MODERATE
Resolver agreement is inconsistent for some protocols, limiting confidence. Data currency and system maturity are adequate.
Email Spoofing
Partial
Brand Impersonation
Not Set Up
DNS Tampering
Protected
Certificate Control
Open
What Requires Attention
Recommended Move DMARC policy from 'none' to 'quarantine' or 'reject'
The BIG Questions
Can this domain be impersonated by email? Yes DMARC is monitor-only (p=none)
Can DNS itself be tampered with? No DNSSEC signed and validated, cryptographic chain of trust verified
Can this brand be convincingly faked? Likely DMARC is monitor-only p=none (RFC 7489 §6.3) — spoofed mail is not blocked, brand faking is trivial
Is mail transport encryption enforced? Yes DANE/TLSA provides cryptographic transport verification
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
