DNSSEC
Unsigned
U/-/-
Meaning: Shows whether DNSKEY data is observed at the apex (signed), absent (unsigned), or unavailable due to lookup error.
Apex DNSKEY presence only — not full chain validation.
Analyze on DNSViz
📌 Action item(s):
- Enable DNSSEC signing and publish a DNSKEY at the apex. Use DNSViz to validate the full chain.
DMARC
p=reject
p=reject — published organizational policy. Strongest published policy (SPF/DKIM alignment still not measured here).
Meaning: Published DMARC policy at _dmarc.caymanairways.com (DNS TXT). Shows organizational policy (p=) and subdomain policy (sp=) when set.
Record at _dmarc.caymanairways.com:
v=DMARC1; p=reject; rua=mailto:adminalerts@caymanairways.net
Policy publication only — SPF/DKIM not measured. Not part of the 0–4 row score.
