# How do you protect customer data?

Protect customer data by collecting only what you need, encrypting it in transit and at rest, limiting access by role, requiring SSO and multi-factor authentication, logging who accessed what, vetting vendors and AI tools for how they store and use data, training staff, deleting data you no longer need, and having a tested incident response plan.

## Ten practices

1. **Minimize** what you collect and keep.
2. **Encrypt** data in transit and at rest.
3. **Control access** with roles and least privilege.
4. **Use SSO and MFA**, and automate user provisioning with SCIM.
5. **Log access and changes**, and review the logs.
6. **Redact sensitive fields** such as card numbers in tickets and AI prompts.
7. **Vet vendors**, including AI providers: data retention, training use, certifications.
8. **Train staff** on phishing and data handling.
9. **Delete on schedule** and honor deletion requests.
10. **Prepare for incidents** with a plan, contacts and customer communication templates.

## AI-specific risks

| Risk | Control |
|---|---|
| AI sees more than the user should | Permission-aware retrieval |
| Sensitive data in prompts | Redaction and data-loss rules |
| Unclear storage | Audit what the AI stored and allow deletion |
| Unapproved actions | Approval gates and logs |
