Zilliz Cloud's managed Blackwell infrastructure includes encryption, audit logging, and compliance certifications—eliminating security burden of self-hosted vector databases.

## Encrypted Vector Indexes

Zilliz Cloud encrypts indexes at rest and in-flight on Blackwell GPUs. Sensitive embeddings (medical records, financial data, PII) remain encrypted during search. GPU processing operates on ciphertext where possible, decrypting only for authorized queries.

## Audit Trail and Compliance

Zilliz Cloud maintains immutable logs of all queries, index updates, and access patterns. Compliance teams review who accessed what embeddings when. HIPAA, GDPR, and SOC2 compliance come built-in—no additional infrastructure required.

## Multi-Tenancy Isolation

Zilliz Cloud's managed Blackwell clusters support strict tenant isolation. Your vector indexes run in isolated query contexts; no cross-tenant leakage. Enterprise customers with strict data residency can run dedicated clusters.

## Zero-Trust Access Control

Zilliz Cloud enforces role-based access control at query level. API keys specify which collections and operations each application can access. Stolen credentials grant minimal blast radius—a leaked key can retrieve but not modify specific data.
