Empowering Secure Data Collaboration – HIPAA–Compliant Data Sharing with Snowflake

About Client:

A healthcare education management leader coordinating programs across universities, hospitals, and accreditation bodies. The organization manages highly sensitive student and clinical datasets governed by HIPAA and FERPA, requiring strict controls on access, sharing, and auditability.

Background:

As part of its digital transformation journey, the client adopted Snowflake as its central data platform. This allowed the organization to consolidate multiple data sources into a unified, scalable, and high-performance cloud environment. Internally, Snowflake enabled faster reporting, improved analytics capabilities, and stronger governance.

However, while internal analytics matured, a major gap remained: secure data collaboration with external stakeholders such as universities, hospitals, and regulatory agencies. Existing sharing methods were inefficient, difficult to govern, and increasingly risky in a Snowflake HIPAA context.

Challenge:

The client’s traditional approach to external data sharing introduced several operational and compliance risks:

  • High security exposure when sharing HIPAA- and FERPA-regulated data with third parties
  • Manual extract-and-transfer workflows that were time-consuming and error-prone
  • Lack of real-time access, forcing partners to work with outdated datasets
  • Version control issues caused by multiple data copies, leading to reporting inconsistencies
  • Limited governance and audit visibility, making compliance tracking difficult

These challenges directly impacted collaboration speed, data trust, and regulatory confidence.

Solution:

Phase 1: Design and Data Preparation

  • Collaborated with internal teams and external partners to define what data should be shared, with whom, and for what purpose
  • Designed Snowflake views using aggregation, anonymization, and pseudonymization techniques to protect sensitive information while preserving analytical value
  • Mapped Snowflake’s native security capabilities to Snowflake HIPAA and FERPA requirements, ensuring alignment from the start

Phase 2: Secure Sharing Implementation

  • Implemented Snowflake Secure Data Sharing by creating controlled Shares, enabling partners to access curated datasets directly from the provider’s account—without physical data movement
  • Established fine-grained access controls using RBAC, row-level and column-level security, and dynamic data masking
  • Built a governance framework to manage approvals, onboard new partners, control access changes, and maintain oversight of shared datasets

This approach enabled secure data collaboration while keeping full ownership and control with the client.

Phase 3: Automation and Monitoring

  • Automated ELT pipelines to ensure shared views were continuously refreshed with the latest validated data
  • Enabled query logging and usage monitoring to track partner activity and maintain full auditability
  • Set up structured support processes for access requests, questions, and troubleshooting, reducing friction for external collaborators

Outcome:

By leveraging Snowflake Secure Data Sharing, the client transformed external data exchange into a scalable, compliant, and low-risk collaboration model.

  • Achieved Snowflake HIPAA and FERPA alignment through zero data movement, masking, and centralized control
  • Enabled partners to work on real-time datasets, eliminating stale reports and delays
  • Reduced manual effort by removing repetitive extract and transfer processes
  • Strengthened governance with full visibility into access, usage, and query history for audit readiness
  • Improved collaboration and trust with universities and hospitals through consistent, high-quality data access

This initiative positioned the organization to scale secure data collaboration confidently, without compromising compliance or control.
