Due Diligence Checklists
Vendor due diligence is essential for deployers — you remain responsible for how you use AI, even when it's built by someone else. Klarvo provides structured checklists to systematically evaluate your AI vendors.
The Due Diligence Checklist
Each vendor has a checklist covering key areas:
Section 1: Vendor Identification (VEN-01)
Section 2: AI System Description (VEN-02)
Section 3: Security & Data Protection (VEN-03)
Section 4: Transparency Support (VEN-04)
Section 5: Logging & Export (VEN-05)
Section 6: Incident Communication (VEN-06)
Section 7: EU AI Act Readiness
Completing the Checklist
Completion Scoring
Klarvo shows a completion percentage:

| 70-89% | Good — some gaps to address |
| 50-69% | Moderate — significant gaps require attention |
| Below 50% | Inadequate — prioritize completing this checklist |
Renewal Reviews
Due diligence should be reviewed:
Best Practices
📋 Request documentation at procurement: The easiest time to get vendor docs is before you sign
🔄 Set renewal reminders: Don't let due diligence go stale
📄 Attach evidence to each item: A checked box without evidence has limited audit value
⚠️ Flag gaps clearly: If a vendor can't provide something, document the gap and your risk acceptance
