Security controls for legacy models

Caution: The Pathways Language Models (PaLM) are deprecated. As of October 9, 2024, you can no longer access these models from new Google Cloud projects, and access for all projects will be removed on April 9, 2025. If you're a new user, we recommend using Gemini. If you're an existing PaLM user, see Migrate from PaLM 2 to Gemini.

This page details the security controls for legacy models on Vertex AI. The models in a legacy model family are no longer updated with new stable versions. For details, see Legacy model information. Vertex AI implements Google Cloud security controls to help secure your models and training data.

The following table lists the security controls available for Generative AI features:

	Data residency (at-rest)^1	Customer-managed encryption key (CMEK)	VPC Service Controls (VPC-SC)	Access Transparency (AXT)
