C100 — Top 100 CISOs.
The C100 recognizes the chief information security officers who set the gold standard in protecting their organizations while shaping the future of the cybersecurity profession. Nominations are open to enterprise CISOs across industries; judging is conducted by a board of standing CISOs and security executives — there is no analyst desk between nominees and recognition.
The 2026 cohort marked a milestone with the inclusion of international judges, reflecting that security leadership challenges and solutions transcend borders. Winners are announced in December. Judging weighs demonstrated program outcomes and peer standing — not nomination volume or vendor relationships.
