Enterprise Security & IAM
Enterprise Security Architecture on Google Cloud
Unlike consumer AI offerings, Vertex AI operates strictly within your Google Cloud enterprise security boundary. It natively integrates with Cloud IAM, VPC Service Controls (VPC-SC), Cloud KMS (Customer-Managed Encryption Keys), and Cloud Audit Logs.
Zero Training on Customer Data (ZDR)
When you interact with foundation models (such as Gemini 3.8 Flash or Gemini 2.5 Pro) through Vertex AI, Google provides a legally binding contractual guarantee: your prompts, inputs, and generated completions are never used to train Google foundational models, nor are they exposed to other customers.
Identity & Access Management (IAM) Roles
Granular IAM permissions allow administrators to enforce the principle of least privilege across machine learning projects:
roles/aiplatform.user: Authorizes invoking deployed online prediction endpoints, running inference against Gemini models, and querying feature stores.roles/aiplatform.viewer: Read-only access to inspect pipelines, model registry artifacts, metadata, and dataset schemas without making changes or running inference.roles/aiplatform.admin: Full administrative privileges to deploy custom models, configure VPC service perimeters, allocate endpoints, and adjust quotas.
VPC Service Controls & Data Residency
By placing your Vertex AI resources inside a VPC Service Controls security perimeter, you mathematically prevent data exfiltration. Vertex AI endpoints cannot communicate with untrusted internet destinations. Furthermore, Vertex AI supports strict Data Residency: you pin model execution and prompt processing to specific Google Cloud regions (e.g., europe-west4 in Eemshaven, Netherlands or us-central1 in Iowa), ensuring strict compliance with GDPR, HIPAA, and regional sovereign AI regulations.
# Grant minimum inference permissions to a microservice service account
gcloud projects add-iam-policy-binding PROJECT_ID \
--member="serviceAccount:ai-service-runner@PROJECT_ID.iam.gserviceaccount.com" \
--role="roles/aiplatform.user"
# Enforce VPC-SC ingress/egress perimeter around Vertex AI
gcloud access-context-manager perimeters update SECURE_AI_PERIMETER \
--add-restricted-services="aiplatform.googleapis.com"
Assign fine-grained enterprise IAM roles to a Vertex AI service account ensuring least-privilege access for automated training and model inference.
