Challenge
The healthcare provider’s legal and compliance teams were deeply reliant on legacy Veritas tools for eDiscovery, complicating efforts to modernize their IT environment. As the organization moved toward Microsoft 365 adoption, the lack of alignment between legacy systems and cloud-native governance created operational friction. At the same time, overlapping HIPAA, OCR, and vulnerability management initiatives demanded a solution that could meet strict regulatory requirements without disrupting existing workflows.
Solution
Arcova led a structured, stakeholder-driven transition to Microsoft 365 Purview eDiscovery Premium. The engagement began with a Microsoft-led briefing, followed by targeted O365 working sessions and a NIST readiness assessment tailored to Microsoft 365. A phased roadmap was developed to support legal and compliance use cases, while aligning with healthcare governance standards. The team also advanced a data protection program including classification schema design, label simulation, and DLP planning. Proofpoint was decommissioned, and governance artifacts were delivered to support executive decision-making.
Impact
The healthcare provider successfully aligned its eDiscovery and data protection strategy with Microsoft 365, reducing reliance on legacy tools and improving governance maturity. Legal and compliance teams gained confidence in Purview’s capabilities, while structured reporting and stakeholder coordination enabled predictable decision-making. The organization is now positioned for Copilot readiness and improved PHI handling, with a clear roadmap for continued security and compliance uplift.
