description: >-
  TLS, HSTS and DNS posture for rapidsilicon.com, Rapid Silicon's registered corporate domain. The
  domain is still registered to the company through GoDaddy (registry expiry 2027-06-14) and its mail
  exchange still points at Microsoft 365 with a hard-fail SPF record and a DMARC policy, but since
  2026-05-25 the web origin no longer serves company content. Absence of a record below is a measured
  observation, not an omission.
