- Anomaly detection - Pre-built algorithm functions for the identification of events which do not conform to an expected pattern in a data asset

- Visualization - Dashboards that can report the state of data quality


- Real Time - The data quality checks can be executed in real-time to detect issues faster

- Extensible - The solution can work with multiple data systems
