Known Gaps (Non-Blocking, Tracked for Certification)
1. Break-glass access procedure — present as model but needs a runbook and quarterly audit. 2. On-call rotation (Incident Response) — requires operations headcount; planned Phase 2. 3. DLP scanning on outbound email — planned Phase 3. 4. Physical media policy — pending office occupation. 5. Corporate MDM for staff laptops — pending. 6. DAST in CI — planned Phase 2. 7. Quarterly tabletop exercises — planned Phase 2. 8. Penetration test — planned before Phase 4 production cutover. 9. Long-term audit log archival tier (Glacier) — planned Phase 2.
These gaps are explicitly accepted by the DPO and CEO as non-blocking for the platform launch provided they close within the first full assessment cycle.
