Problem
Employees use ChatGPT, Copilot, or AI tools without a clear framework.
Expected outcome
A simple AI policy, technical guardrails, and an approval process.
Identify unapproved usage
Shadow AI creates data flows invisible to IT teams.
- Survey teams on tools used.
- Analyze browser extensions and connected SaaS.
- Classify usage by risk level.
Define what must never be submitted
The rule must be concrete: customer data, secrets, proprietary code, contracts, and HR information.
- Create a red list of forbidden data.
- Train teams with prompt examples.
- Add human review for sensitive decisions.
Deploy guardrails
Technical controls prevent the policy from staying theoretical.
- Use enterprise accounts with training opt-out.
- Enable DLP and logging.
- Validate AI vendors before purchase.
Frequently asked questions
Can prompts expose data?

Should AI be banned?
No. Usage should be governed, tools selected carefully, and teams trained.
What is the minimum AI policy?
Allowed use cases, forbidden data, approved tools, and validation responsibilities.
