DeltaStream emphasizes robust data security and privacy by implementing a zero trust strategy, where security verifications exist at multiple levels to minimize exposure in case of breaches. The platform ensures queries for data processing are run in isolated environments using Apache Flink, preventing unauthorized access and resource competition. DeltaStream stores only necessary data, securely encrypting any data at rest or in transit. Users can choose between Public, Dedicated, or Bring Your Own Cloud (BYOC) deployment models, allowing them to select the best option for their security needs. Additionally, DeltaStream offers federated data governance by combining data federation and governance, simplifying access control through a hierarchical namespace model and Role-Based Access Control (RBAC) for managing permissions across disparate data sources. This approach helps organizations share data securely on a need-to-know basis, reducing management overhead and potential errors.
