  IMPORTANT PROVENANCE. Neither the Australian retail brand (simplyenergy.com.au,
  engie.com.au) nor either live CDR host (public.cdr.engie.com.au,
  cdr.energymadeeasy.gov.au) publishes a security.txt, a responsible-disclosure page or a bug
  bounty. `probe-security-programs.py` returned vdp=none for this provider on 2026-07-27, and
  every /.well-known/security.txt probe against those four hosts returned 404 or a Cloudflare
  403.

  What DOES exist is a group-level programme published by the ultimate parent, ENGIE SA
  (France): a PGP-signed RFC 9116 security.txt at https://www.engie.com/.well-known/security.txt
  and ENGIE CERT with a published RFC 2350 profile. The Australian entities trade as ENGIE and
  their endpoints sit on ENGIE-branded domains, so this is the route a researcher would
  realistically use to report a flaw in public.cdr.engie.com.au - but it is a PARENT-GROUP
  programme, not an Australian retail publication, and must not be reported as the latter.
