Snowflake Dynamic Data Masking in Action: A Financial Services Case Study

As data volumes grow and compliance demands intensify, data governance teams face challenges in protecting sensitive information like PII without hindering analytics. Snowflake's dynamic data masking offers a scalable solution by allowing organizations to define masking policies at the column level based on user roles, ensuring sensitive data protection without data duplication. This approach, championed by Yomar Marquez at Rise Analytics, automates PII protection while enabling scalable self-service analytics, serving as a model for modernizing governance without compromising speed or trust. Rise Analytics utilizes Select Star to automate PII classification and lineage tracking, allowing for real-time policy enforcement at query execution, which enhances compliance and reduces manual overhead. This method empowers data teams to maintain strong privacy protections while facilitating internal data access and accelerating insight delivery, demonstrating the effectiveness of dynamic data masking in achieving secure and efficient data governance.
