Deputy Tier · Inaugural 2025

Deputy C100 — Top 100 Deputy CISOs.

The Deputy C100 is the inaugural recognition for the deputy-CISO tier — the operating leaders running the day-to-day of enterprise security programs. The deputies do much of the work that makes a CISO's strategic posture executable. The program names them.

Same practitioner-judged rigor as the flagship program

The 2026 nomination window opens with the same rigor as the C100 and A100: practitioner-judged, peer-reviewed, signed. There is no separate application track — deputy-tier leaders are evaluated on the same operating-outcomes standard as the flagship program, scoped to the deputy role.
