  Vulnerability disclosure posture for Nasdaq Calypso Workstation. Calypso
  Technology was acquired by Adenza and Adenza by Nasdaq, Inc. in 2023; the
  product now ships as Nasdaq Calypso from www.nasdaq.com and calypso.com no
  longer resolves, so the applicable disclosure program is the Nasdaq, Inc.
  corporate program rather than a product-specific one.
ownership_note: >-
  This is a parent-brand attribution. The HackerOne program is registered to
  Nasdaq (handle "nasdaq", program id 6048, profile website nasdaq.com), the
  same legal entity that publishes the Calypso product pages at
  www.nasdaq.com/products/fintech/calypso. No Calypso-specific disclosure
  program or security.txt was found on any Calypso host.
