source: live DNS/TLS/HTTP probes of apis.yml + OpenAPI hosts
note: >-
  The centrical.com row is written by 0-working/probe-domain-security.py from apis.yml. The
  centrical.me rows were measured by hand on 2026-08-10 with the same method (openssl s_client for
  TLS version and cert expiry, HEAD for HSTS, dig for DS/CAA/SPF/DMARC) after a DNS sweep found
  Centrical's production application and API hosts on its second domain, which apis.yml does not
  reference. Two findings worth naming: centrical.com sets an HSTS max-age of only 300 seconds
  (5 minutes), which is far too short to offer real protection and below the 31536000 the
  centrical.me app hosts use; and api.centrical.me — the production API host — sends no HSTS header
  at all. Neither domain publishes DNSSEC or CAA.
