linear-technology-domain-security.yml Raw ↑ 
generated: '2026-07-19'
method: probed
source: live DNS/TLS/HTTP probes of linear.com (the entity's own domain) and its redirect target
note: Linear Technology was acquired by Analog Devices (closed 2017-03-10). The linear.com domain is still
  registered and resolving, but is operated by Analog Devices and permanently redirects. Both the legacy
  domain and the redirect target are recorded, and labeled, so the successor's posture is never mistaken
  for this entity's own.

    redirect to the Analog Devices "ADI + Linear combine" landing page. Absence is valid, expected data
