Previously available in beta, client-side encryption (CSE) customers can now conduct bulk migrations of sensitive files from both cloud and on-premises data sources. This process ensures confidential content is wrapped with customer-managed keys before it's imported into Google Workspace. Using this tooling, CSE customers can decommission their legacy third-party storage while ensuring the CSE model is in place throughout the document lifecycle. The API is highly configurable, we share a generalized sample code to make deployment simple, but customers can further customize it depending on their needs.
