- HSTS is set on tms.skyhub.jp only (max-age=31536000); the four content sites set no Strict-Transport-Security
  header.
- No domain in the group publishes DNSSEC or CAA records.
- SPF is published for aeronext.com, aeronext.co.jp and skyhub.jp (all Xserver-hosted mail); nextdelivery.co.jp
  has no SPF.
- DMARC exists only on nextdelivery.co.jp, at p=none (monitor-only, no enforcement).
