What this move signals
Tanium named Paul Black as Chief Information Security Officer, with a mandate reported to include AI-focused security priorities. Tanium announced the appointment on May 18, 2026. (Corrected 2026-09-25: this record previously carried a month-level date of May 2026.)
A security vendor's CISO is both defender and reference customer; the explicitly AI-scoped mandate mirrors what GitLab signaled with its June appointment — 2026 CISO briefs increasingly name AI in the job description itself.
