1. The visibility gap your auditors will ask about first.
98% of employees use AI apps the security team has not sanctioned. ChatGPT, Claude, Gemini, a half dozen browser extensions, an internal experiment somebody spun up last quarter and forgot to document. Each of those is a channel out of your perimeter, and none of them appear in your DLP console. 89% of enterprises still have no purpose-built AI security in place, which means there is no log, no pattern library, no inline mask sitting between a customer record and an external model. When the audit asks "show us what data crossed the boundary in Q1," the honest answer is "we cannot tell you." That answer used to be acceptable. It is not anymore.
