  Blackstone runs a published Responsible Vulnerability Disclosure programme covering
  applications and systems on Blackstone-owned domains. Reports go to the Blackstone
  cybersecurity team by encrypted email; the team acknowledges properly submitted reports within
  five business days. It is a disclosure programme, not a bug bounty — Blackstone states it does
  not offer rewards or compensation.

    The programme page publishes a cybersecurity-team address, but the address was masked in
    every index snippet available to this pass and the page itself could not be fetched directly
    (see x-evidence). Not recorded rather than guessed.

security_txt:
  served: false
  note: >-
    No RFC 9116 security.txt is served on any Blackstone host — the policy exists only as an HTML
    page. Publishing /.well-known/security.txt with a Policy and Contact line pointing at this
    same page would make the programme machine-discoverable at zero policy cost. This is the
    provider's to fix.

      Direct fetch blocked. www.blackstone.com returns 403 with `cf-mitigated: challenge` for
      every non-browser client, including full browser header sets and archive proxies. The
      policy content recorded above was read from a public search index that had crawled the
      page, not from our own fetch. Confidence in the programme's existence: high (the URL is a
      live Blackstone-owned path with indexed policy text). Confidence in the exact field values:
      medium.
