notes:
- >-
  toolsportal.landisgyr.com is the weakest host — TLS 1.2 with no HSTS — and it is the
  customer login surface. Every other resolving host negotiates TLS 1.3.

  Hosts probed but excluded from the table: eu.landisgyr.com (EMEA property, divested to
  AURELIUS in 2026) and careers.landisgyr.com (third-party jobs2web ATS).
