  Live DNS/TLS probes of every registrable domain Acutus Medical, Inc. owns (acutus.com and
  acutusmedical.com) on 2026-09-06. No apis.yml Website/Portal host and no OpenAPI servers[] host
  exist to probe, because the company no longer publishes a web surface — both zones are delegated
  to Cloudflare nameservers and serve mail records only.
note: >-
  Neither apex resolves to an address: acutus.com answers NOERROR with zero A records and
  www.acutusmedical.com answers NXDOMAIN, so no TLS handshake is possible and HSTS cannot be
  observed. The zones are not empty — both still carry Microsoft 365 MX records
  (acutus-com.mail.protection.outlook.com / acutusmedical-com.mail.protection.outlook.com), a
  secondary MX at vor.acutusmedical.com, and a hard-fail SPF record, so corporate email continues
  to route while the public web presence has been withdrawn. Neither domain publishes DNSSEC, CAA
  or a DMARC record; SPF without DMARC leaves the mail posture unenforced.
