  Centene runs a coordinated vulnerability disclosure program on HackerOne. Found by search and
  verified by direct fetch (HTTP 200). Centene does NOT serve a /.well-known/security.txt on any
  host - all twelve hosts were probed and every one returned 404, 403 or 401 - so the program is
  discoverable only if a researcher already knows to look on HackerOne.

    Not established from the public page. Listed as a Vulnerability Disclosure Program, which on
    HackerOne is conventionally non-paying, but no reward table is published anonymously.
  scope_note: >-
    The program page states researchers must obtain explicit consent from the organization before
    conducting security testing against its mobile apps or APIs, and must report findings promptly
    and responsibly.

  recommendation: >-
    A three-line RFC 9116 security.txt at https://www.centene.com/.well-known/security.txt with
    Contact: https://hackerone.com/centene_vdp would make an existing program machine-discoverable
    at no cost. The program is the hard part and Centene has already done it.
