Cosm Domain Security

generated: '2026-08-11'
method: probed
source: live DNS/TLS/HTTP probes of every Cosm-operated host found on the public site
note: >-
  Cosm publishes no API host, so the probe covers the six web hosts it operates plus
  the legacy Evans & Sutherland support host. The finding worth flagging is
  support.es.com — the "Access Portal" the Digistar product page still links for
  documentation and support. Its TLS certificate has EXPIRED, so https fails outright;
  over plain http it serves an 786-byte meta-refresh to partners.cosm.com. No host
  outside the Salesforce-operated partner portal sends HSTS, and neither cosm.com nor
  es.com publishes DNSSEC or CAA.

    Linked as the Digistar "Access Portal" from
    https://tech.cosm.com/products/digistar-projection-system/digistar. https is
    unusable (expired certificate); http 200 returns a meta-refresh landing page
    announcing the move to https://partners.cosm.com/.
