findings:
- >-
  No HSTS on any of the five live API/authorization hosts, including the OAuth 2.0 authorization server
  that issues tokens carrying PHI scopes. Only the marketing host www.cerner.com sets
  Strict-Transport-Security. This is the most notable gap in this profile.
- >-
  cerner.com publishes no CAA record, so no certificate authority is pinned for the domain that hosts
  every live API endpoint. oracle.com does pin three (digicert, pki.goog, letsencrypt).
- No DNSSEC on either registrable domain.
- SPF and DMARC are present on both domains with DMARC policy p=reject.
