  live DNS/TLS/HTTP probes of the apis.yml hosts (0-working/probe-domain-security.py) extended
  by hand to every operating Blue Cross member-plan host in the federation
hosts:
- host: www.bluecross.ca

  note: >-
    HSTS max-age of 300 seconds is far below the 31536000 the member plans use and below any
    preload threshold — effectively a token policy on the national brand site.

  note: >-
    DMARC is published but at p=none (monitor only), so no enforcement against spoofed mail from
    the brand domain. No CAA records, so certificate issuance is unconstrained. No DNSSEC.

  spf: true
  dmarc: true
  dmarc_policy: none
  nameservers: [simon.ns.cloudflare.com, kia.ns.cloudflare.com]
  note: >-
    SPF and DMARC are delegated to Proofpoint (pphosted.com); DMARC is also p=none. No CAA, no
    DNSSEC.
summary:

  tls13_everywhere: true
  hsts_hosts: 7
  dnssec_domains: 0
  caa_domains: 0
  dmarc_enforcing_domains: 0
  note: >-
    Transport hygiene is uniformly good across the federation; domain-level controls (DNSSEC,
    CAA, DMARC enforcement) are uniformly absent.
