Shadow AI governance for internal data leakage

April 3, 2026r/AskNetsec

In r/AskNetsec, security teams are trying to govern unsanctioned LLM use where staff paste internal data into public tools via extensions and embedded copilots, shifting toward allowlists, SSO, API key brokering, and endpoint prompt inspection.

We have people feeding internal data into public LLMs through browser extensions, embedded copilots in productivity apps, and standalone chatbots.
Traditional DLP and CASB solutions seem to miss a lot of this.
We whitelist approved AI, kill browser extensions, force SSO, proxy API keys through a broker, and inspect prompts at the endpoint, not just CASB.
