Classifications are a fundamental component of Qanapi's **Zero Trust** architecture, serving as the policy engine that defines granular access controls and data handling rules for your sensitive information. By tagging data with classifications, you can strictly control who can access it and how it is processed across different services, including direct API usage and our Live Redaction integration for Google Docs™. ## Access Control Classifications act as gatekeepers for your encrypted data. You can manage access at a granular level by assigning: Grant specific application users the ability to encrypt or decrypt data associated with a classification. Any user in your **Users** area can be added directly to a classification. Assign roles to a classification to manage access for groups of users within your application. Any of the 4 roles can be directly assigned to classifications. This ensures that only authorized entities can perform cryptographic operations on data protected by a specific classification through the API. ## Live Redaction Integration Classifications are essential for **Live Redaction**, enabling secure data masking and encryption based on organizational identity. This is the central mechanism for allowing users with different access to view the same document. ### Provider Configurations & Google Groups You can add **Provider Configurations** to a classification and specify **Google Groups**. This integration allows Qanapi to verify membership in these groups before granting access to encrypted data, bridging your organizational identity with your data security policy. ### Enabling Encryption To enable encryption within Live Redaction, you **must** assign any relevant classifications to your provider configuration. Without this assignment, Live Redaction will not have the necessary context to perform encryption operations. This is done ## Creating Classifications You can manage your classifications through two primary methods: Create and manage classifications in the site at the **Classifications** link in the sidebar. Programmatically manage classifications using the API. See the [Classifications API Reference](/api-reference/list-classifications) for more details.
