Use business accounts

Personal accounts make governance and audit nearly impossible.

  • Centralized accounts.
  • Validated privacy settings.
  • Logging where available.

Ban certain data

Employees need examples, not abstract rules.

  • No customer data.
  • No secrets or API keys.
  • No non-public contracts.

Validate sensitive outputs

AI can hallucinate, oversimplify, or invent references.

  • Mandatory human review.
  • Verified sources.
  • No high-risk automated decisions.

Frequently asked questions

Can ChatGPT be used with customer data?

Is a policy enough?

No, it must be supported by training, controlled accounts, and guardrails.
