  note: >-
    30-day HSTS max-age, below the one-year threshold required for preload eligibility. Fronted
    by Cloudflare. Additional response headers observed - x-content-type-options nosniff,
    x-frame-options sameorigin, x-xss-protection 1; mode=block, and x-powered-by ASP.NET, which
    discloses the server stack unnecessarily.

  note: >-
    No Strict-Transport-Security header on the login wall used by 414 member brokerages. This is
    the most consequential gap found in the estate.

  note: >-
    The only Steadfast domain with DNSSEC signing and CAA records - and it is a divisional site,
    not the primary domain. The divergence suggests it sits with a different registrar/host than
    the corporate estate.

findings:
- >-
  Email authentication is consistently strong: SPF everywhere and DMARC at p=reject on four of
  five domains - a meaningful control for a broker network exposed to invoice and premium fraud.
- >-
  DNSSEC and CAA are absent on the primary steadfast.com.au domain and on every domain except
  steadfastlife.com.au. Nothing constrains which certificate authority may issue for the
  corporate or API hosts.
- >-
  HSTS is inconsistent across the estate, ranging from ten years with includeSubDomains on the
  identity provider to entirely absent on the broker login wall and both partner API hosts.
- >-
  Two hosts still negotiate TLS 1.2 as their top protocol, including the public API host and the
  identity provider.
