Case Study: Fortune 500 Healthcare Company secures its data lake and accelerates AWS migration with Okera

Okera Helps Fortune 500 Healthcare Provider Secure Its Data Lake and Protect Sensitive Data

A Fortune 500 Healthcare Company needed to accelerate its move from an on-premise Cloudera data lake to AWS S3 and EMR, but its existing IAM-based access controls were too limited for the fine-grained security and compliance requirements of a regulated healthcare environment. The company turned to Okera and its Active Data Access Platform (ODAP) to help secure sensitive data while supporting current and future analytics tools.

Okera implemented unified data access control across analytic engines, with fine-grained column-, row-, and cell-level policies plus dynamic obfuscation features such as masking, tokenization, pseudonymization, and redaction. As a result, the company sped up its migration to Amazon S3 and Amazon EMR, gained stronger governance and regulatory protection, and expanded analytics capabilities beyond what was possible on Cloudera.
