In a 2025 study of employee generative AI use, 21% used ChatGPT in free, personal accounts, where data becomes part of LLM training data. And 7% of employees used Chinese generative AI tools at work. (Study by @harmonicsec of their users) The problem is that an AI ban won't create security. Bans create invisibility. If you see shadow AI as a design constraint and worked to turn it into something visible, measurable, and well-governed, instead of trying to suppress it with blanket bans, we want to hear from you. @SANSInstitute AI Summit 2026 has a full track on AI Governance & Risk. We want enterprise AI inventory methodologies with actual numbers. Framework implementations with measurable outcomes. EU AI Act compliance stories--what broke, what worked. Cross-functional governance models that survived contact with reality. The CFP is open until Friday, January 16 at 5pm ET. Submit yours here: app.smartsheet.com/b/form/01…
