First True Anonymization

Solution to Provide

High-Quality Analytics

Aircloak’s unique approach ensures the existing primary database is not modified in any way. Aircloak handles all data types including unstructured text.

Aircloak offers analysts a rich explorative SQL database interface. Analysts submit SQL queries and interact with the existing database to extract the requested data.

Both the queries and responses are dynamically modified by Aircloak to ensure anonymity while still providing high accuracy.

Aircloak Insights offers banks instant analytics that comply with complex regulations. Our approach to anonymization is compliant with the General Data Protection Regulation (GDPR), irrespective of the type of data.

  • Better understand the ever-evolving needs of the modern-day customer
