moderate

Query Data

Executes semantic SQL queries against connected data sources.

Potential for data exfiltration if queries are not properly controlled.

high

Define Semantic Model

Creates and manages the semantic layer, defining business terms and data relationships.

Incorrectly defined models can expose sensitive data or lead to inaccurate reporting.

high

Manage Connections

Adds, modifies, and deletes connections to data sources.

Compromised connections can grant unauthorized access to sensitive data.

Safety Assessment

Wren Engine's safety depends on the configuration of its semantic layer and the security of the underlying data sources. It is relatively safe for data analysis and reporting when access controls are properly configured. Risks increase when the semantic layer is poorly defined or when connecting to untrusted data sources.

Semantic layer adds a level of abstraction, reducing direct data access risks.
Supports user-based permissions and access control.
Designed to be governance-ready, respecting roles and definitions.
Primarily focuses on data retrieval and analysis rather than direct system modification.

Connections to various data sources (databases, cloud storage) introduce potential vulnerabilities.
Improperly configured semantic models could expose sensitive data.
Complex data interactions increase the risk of unintended data exposure or manipulation.
Requires careful management of connection credentials and access rights.
