Case Study: Large Healthcare Provider achieves secure, compliant patient and partner email protection with Proofpoint Secure Email Relay

Large Healthcare Provider Protects Patients and Partners With Proofpoint Email Security

This large, not-for-profit regional healthcare provider serving five states relies heavily on email—sending roughly a quarter-million messages daily—to communicate with patients, physicians, insurers and vendors. As it migrated some systems to a new platform, the organization needed to secure transactional email, protect patient data and its brand, and control costs while preventing compromised third-party senders from abusing its domains.

The provider deployed Proofpoint Secure Email Relay, a hosted solution that consolidates and protects emails from internal applications (like Epic and Salesforce) and third-party SaaS partners. The relay enables DKIM signing, payload encryption and DLP, improves sending reputation to reduce blocklisting, and was quicker and more cost-effective than alternatives—helping the organization maintain compliance, safeguard PHI/PII, and preserve patient and partner trust.
