Case Study: Major U.S. Healthcare Company achieves consolidated email security and enhanced customer data protection with Mimecast

Major U.S. Healthcare Company Prescribes Mimecast to Protect Customer Data

A major U.S. healthcare company with thousands of locations and several hundred thousand Microsoft 365 email accounts needed to protect PHI and PII while simplifying a fragmented email security stack. They were managing multiple vendors (including Proofpoint), lacked a single, easy-to-access console, and wanted a true, proactive partner rather than a reactive supplier.

Mimecast consolidated the company’s email security under one platform, completing a planned nine-month migration in just 2.5 months and delivering a unified console that reduced routine administration. The solution enabled secure message recall and read-status visibility for mis‑sent emails, improved compliance, and freed the security team to focus on higher-value issues while building an ongoing partnership with Mimecast.
