What Business Data Should Never Be Entered into Public AI Tools?

Once a business decides employees can use AI tools, the next question is immediate and practical: what's actually safe to type into them? Most employees don't have a clear answer, and most businesses have never written one down. A simple classification framework fixes that—not with a long policy document, but with a mental model employees can apply in seconds.

The problem with "just use good judgment"

Telling employees to "use good judgment" about AI tools sounds reasonable, but it puts the entire risk decision on someone who usually has no visibility into what happens to data once it leaves your systems. Different AI tools have different data retention and training policies. Without a shared standard, you get inconsistent decisions—some employees overly cautious and unproductive, others pasting in things they shouldn't.

A simple framework: Green, Yellow, Red

Green — safe to use freely

Public information, general knowledge questions, drafting generic content, brainstorming, and anything that wouldn't matter if it were seen by anyone. Examples: drafting a generic marketing email, summarizing a public article, asking for help structuring a document.

Yellow — use only with an approved, vetted tool

Internal-but-routine business information: meeting notes, internal process documents, non-sensitive operational data. Not public, but not catastrophic if handled carefully within a tool your business has actually reviewed and approved—not just whatever the employee happens to have open.

Red — never enter into any AI tool without explicit approval

Customer personal data, financial records, legal documents, unreleased business plans, credentials, health information, anything covered by a confidentiality agreement or regulatory requirement. This category should be handled through approved, governed systems only—if at all—not through general-purpose AI chat tools.

Why this works better than a long policy document

A color-coded framework is fast to remember and fast to apply in the moment, which is exactly when the decision actually gets made—at the point of pasting something into a chat box, not during a policy training session three months earlier. Pair it with a handful of concrete examples relevant to your business, and most employees will internalize it quickly.

This is a starting point, not a finished governance program

Data classification is one piece of a broader AI governance approach that also covers tool approval, monitoring, and incident response. But it's the piece that has the most immediate, practical impact on day-to-day risk—which is exactly why it's worth getting in place first.
