Security Overview
Vertex AI security encompasses multiple layers including infrastructure security, data protection, model governance, access control, and continuous monitoring. The platform integrates deeply with Google Cloud's security infrastructure, providing enterprise-grade protection through features like VPC Service Controls, Customer-Managed Encryption Keys (CMEK), and comprehensive audit logging.
Organizations must address unique security challenges in AI/ML workloads including protecting sensitive training data, preventing model theft, ensuring prediction integrity, and maintaining compliance with data privacy regulations. Vertex AI provides tools and features specifically designed to address these challenges, from Explainable AI for model transparency to Vertex AI Workbench for secure development environments.

Data Protection
Vertex AI provides multiple layers of data protection to ensure your training data, model artifacts, and predictions remain secure and compliant with regulatory requirements.
Encryption
- • Encryption at rest by default using Google-managed keys
- • Customer-managed encryption keys (CMEK) for enhanced control
- • TLS 1.2+ for all data in transit between services
- • Confidential Computing with Confidential VMs for sensitive workloads
- • Encrypted model artifacts in Cloud Storage
Data Governance
- • Data lineage tracking for compliance and auditing
- • Feature Store with built-in access controls and versioning
- • Dataset versioning for reproducibility and rollback
- • Data Loss Prevention (DLP) API integration for PII detection
- • VPC Service Controls for data exfiltration prevention
Network Security
Implement network-level security controls to isolate your Vertex AI workloads and prevent unauthorized access.

Frequently Asked Questions
Vertex AI provides comprehensive security including Identity and Access Management (IAM), VPC Service Controls for network isolation, Customer-Managed Encryption Keys (CMEK), audit logging through Cloud Logging, data residency controls, and integration with Google Cloud's security services.
Access is controlled through Google Cloud IAM. You can assign predefined roles like 'Vertex AI User', 'Vertex AI Admin', or create custom roles with specific permissions. Use IAM conditions to add additional restrictions based on resource attributes, network location, or time.
Yes, Vertex AI encrypts data in transit using TLS 1.2+ and supports encryption at rest using Google-managed keys or Customer-Managed Encryption Keys (CMEK). You can use Cloud KMS to manage encryption keys and control key rotation policies.
Use VPC Service Controls to create service perimeters that restrict Vertex AI API access to specific VPC networks. Combine with Private Google Access and Cloud NAT to ensure all traffic stays within your private network without internet exposure.
Cloud Logging captures all Vertex AI API calls, authentication events, and administrative actions. Cloud Monitoring provides metrics and alerts. Enable Data Access audit logs to track who accessed what data and when. Use Cloud Asset Inventory for resource tracking.
Vertex AI supports various compliance frameworks including SOC 2, ISO 27001, HIPAA (with BAA), GDPR, and FedRAMP. Google Cloud maintains comprehensive compliance documentation and provides compliance reports for customers requiring certification evidence.
