Case Study: Kelsey-Seybold Clinic achieves email fraud prevention and advanced threat protection with Proofpoint

Kelsey-Seybold Fights Fraud with Email Fraud Defense and Closes the Gap on Advanced Threats with Integrated Protection

Kelsey-Seybold Clinic, a 20-site multispecialty provider and the first NCQA Accountable Care Organization in the U.S., had strong network defenses but identified email as its primary cyber risk—delivering spam, phishing, malicious attachments, and domain spoofing that threatened patient data, wasted staff time, and complicated incident response.

The clinic deployed Proofpoint Email Protection, Targeted Attack Protection (URL and Attachment Defense) integrated with Palo Alto Networks, Threat Response, Email Fraud Defense, Email Encryption, and DLP. Combined sandboxing/rewrite of URLs and automated playbooks let the team remove malicious mail, orchestrate virtual-desktop remediation, and stop unauthorized use of its domains—resulting in blocked spam and malicious links, faster incident response and forensics, stronger data protection, and hundreds of thousands of fraudulent messages stopped.
