Shadow AI: The Unauthorized AI Usage Problem (2026 Guide)
Shadow AI is what happens when an employee signs up for ChatGPT with a work email, pastes a customer list into a free Gemini tab, or asks Copilot to draft a security policy nobody has reviewed. The tool solves a real problem in minutes. The data leaves the building on the way. The security team has no idea it happened. That gap is the core of the shadow AI problem, and it is growing faster than any governance framework in place.
