OVERCOMING HEALTHCARE CLOUD MIGRATION
CHALLENGES FOR SEAMLESS DATA INTEGRATION
The Challenge
The health insurer sought to migrate over 30 independent insurance companies from legacy mainframe systems to a unified, cloud-first infrastructure. This required overcoming data integration obstacles across diverse, siloed systems while ensuring data security, regulatory compliance, and support for API and FHIR standards.
Challenges Faced:
- Fragmented Systems: Merging data and applications from 30+ independent insurance companies into one secure, integrated cloud.
- Data Security & Compliance: Meeting stringent regulatory standards to protect sensitive patient data throughout migration.
- Building Interoperability: Designing a system that enables real-time data exchange across the nationwide network for better patient care.
- Consumer-Centric Design: Creating a modern infrastructure that aligns with patient needs for easy, seamless access to care.
The Solution
The health insurer partnered with Protegrity and Accenture to establish a cloud-first, API- and FHIR-driven infrastructure, enabling secure, seamless migration of its data and applications across 30+ independent health insurance companies to a unified cloud.
- Protegrity Data Protection Platform: Protegrity deployed its Data Protection Platform as the backbone of the health insurer’s Business Continuity Management (BCM) program. This enabled fit-for-purpose data protection that matched advanced methods of data protection to the specific security and access requirements of its various types of critical data, including care management, claims processing, financial transactions, and call center recordings.
- Advanced Privacy Technologies: By applying vaultless tokenization and other advanced privacy-enhancing technologies to its high-sensitivity data, Protegrity created secure pipelines that enabled smooth, compliant migration of that high-value data from on-premises systems to the new cloud environment.


The Outcome
The cloud migration powered by Protegrity’s Data Protection Platform allowed the health insurer to achieve secure, accelerated data integration across its nationwide network. This transformation not only safeguarded sensitive information but also enabled agile service deployment and cost efficiencies. As a result, the insurer now has a scalable infrastructure that enhances patient care and supports future data-driven healthcare advancements.
Immediate Impact
- Data de-risking: By applying advanced, fit-for-purpose data protection directly to the health insurer’s various data types, Protegrity significantly de-risked the entire cloud migration project — protecting against breaches and meeting stringent regulatory requirements.
- Accelerated cloud migration: De-risking the data allowed the health insurer to migrate data and systems to the cloud significantly faster, without having to implement more extensive data security measures or re-write applications for the cloud.
- Rapid ROI — $50M in cost savings: This accelerated and de-risked cloud migration saved the health insurer more than $50 million by avoiding the need to re-write applications or conduct more complicated data migration processes.
Long-Term Benefits
- Frictionless Data Exchange: The flexible data protection provided by Protegrity allows the health insurer to create shared confidence in a central trusted party while offering unique abilities to retain the referential integrity of shared data to validate its marketplace value.
- Data Monetization: Advanced data protection supports new revenue streams by allowing secure, subscription-based access to valuable datasets.
- Enhanced Patient Experience: The cloud infrastructure empowers new patient-centered applications, providing health insights and assistive AI while ensuring data privacy compliance.
- Cost Efficiencies: The streamlined cloud environment reduces infrastructure costs, optimizes care coordination, and supports better health outcomes.

“We’re completely reimagining how data is aggregated in a secure way — not just for health plans but for providers, patients, and other stakeholders. This has the potential to more effectively address health disparities and foster greater consistency and transparency, improve cost efficiencies by reducing spend on infrastructure, streamline inter-plan operations, and improve care coordination to drive better health outcomes. It’s not just sharing the information that matters. It’s how you share it, by making it more accessible to consumers.”
