Proofpoint Report: CISOs Face Growing AI Security Duties Without More Resources

Summary
Proofpoint’s 2026 CISO report finds that many security leaders lack added resources for AI governance. Cloud account takeover is a leading concern, while human risk and departing employees remain prominent factors in data loss.
Key points
- 79% of CISOs say they are expected to manage AI risks without a proportional increase in resources or expertise; 78% consider GenAI a security risk.
- Cloud account takeover or compromise now tops security leaders’ threat priorities, while collaboration platforms lead workplace technology concerns.
- Human risk is identified as the biggest cyber vulnerability by 79% of respondents.
- Among organizations reporting material sensitive-data loss, 93% said departing employees played a role; malicious or criminal insiders were the most commonly identified root cause.
- Although fewer organizations report material data loss, the report says regulatory, financial, recovery, and reputational consequences have increased.
