CISO Spotlights

CISO tenure record

How long has each CISO held the seat?

Most 10-K Item 1C disclosures describe a security program without saying how long its leader has held the role. A smaller number do: this record lists every company this site has found whose most recent Form 10-K states, in its own words, since when its Chief Information Security Officer has held that title. It carries no view on whether a given tenure is long or short.

5 companies on record so far, built as this site reads filings rather than pulled from a feed — a growing record, not a survey or a census of all public companies.
