• Published product descriptions

Internal Information

Requires caution.

Examples:

• Operational procedures
• Internal communications
• Team documentation

Confidential Information

Should be heavily restricted.

Examples:

• Financial reports
• Strategic plans
• Customer databases

Restricted Information

Should never be submitted to AI tools without explicit approval.

Examples:

• Personal customer data
• Legal records
• Authentication credentials
• Payment information

Classification reduces accidental exposure.

Step-by-Step Guide: How to Secure AI Tools Before Business Use
