A new organisational benchmark from IANS and Artico Search suggests that AI security is becoming a defined leadership responsibility at the largest companies, but governance does not yet have a consistent executive home. The firms say 65% of organisations with more than $10 billion in revenue have assigned a head of AI security role. Only 18% use a dedicated position; 47% combine the responsibility with another leadership role. Dedicated roles were reported by 9% of organisations in the $1 billion to $10 billion tier and 6% below $1 billion.
The same report finds that primary accountability for enterprise AI governance rarely sits with the CISO at the largest businesses. Seven per cent of respondents in that tier placed it there, compared with 22% under a chief AI officer. Between 14% and 19% across the three size bands said no single executive was accountable. Board oversight was also uneven: 21% of the largest companies reported a fully implemented committee dedicated to AI ethics or responsible AI. These are self-reported survey findings from two commercial organisations. They still expose a practical control question: a named security lead cannot compensate for unclear decision rights at executive and board level.
