    No RFC 9116 /.well-known/security.txt is served on www.hithium.com, en.hithium.com or
    www.hero-ee.com - all three return 404. The disclosure contact is reachable only by reading
    the HTML page, so an automated scanner will not find it.

    "In accordance with the IEC 62443 series of standards, Hithium has established a robust
    vulnerability management process. Upon receiving a vulnerability report, we promptly provide

  format: numbered bulletins (HESSCS-YYMMNNNN), HTML detail pages, no feed
  machine_readable: false
  machine_readable_note: >-
    Bulletins are rendered from an internal CMS fragment (https://www.hithium.com/ajax/seculist,
    HTTP 200, text/html). There is no CSAF, CVRF, OSV, JSON or RSS representation, so the advisory
    stream cannot be consumed by a machine without scraping.
