notes: >-
  The current API gateway (api.lexware.io) and developer portal
  (developers.lexware.io) serve valid TLSv1.3 certificates but did not return an
  HSTS header on the probed root responses; the customer web app (app.lexware.de)
  does send HSTS (max-age 63072000, includeSubDomains). The primary corporate
  domain lexware.de is DNSSEC-signed with an SPF hard-fail (-all) and a DMARC
  quarantine policy; the lexware.io API domain publishes a strict DMARC reject
  policy. No CAA records were observed on either apex domain at probe time. The
  legacy lexoffice.io API host was retired at the end of 2025 and was not probed.
