Case Study: US Healthcare Company achieves sharp reduction in email threats and halts cloud account takeovers with Proofpoint

Proofpoint’s People-Centric Solution Secures Critical Patient Information from Cyber Attacks

A national healthcare network that brings together roughly 600 independent Ob/Gyn and women’s health practices faced a surge in phishing and malware targeting patient records as it moved to cloud-based apps. With legacy defenses struggling, the organization needed to prevent theft of protected health information, stop email-based attacks, and defend against cloud account compromise to avoid regulatory fines and reputational damage.

The network deployed Proofpoint’s people-centric stack — Email Protection, Targeted Attack Protection (TAP) with SaaS Defense, Threat Response Auto-Pull (TRAP), email DLP, and Cloud App Security Broker (CASB) — to unify DLP across email and cloud, detect compromised accounts, and automate responses. Results included nearly eliminating malicious emails before inbox delivery, cutting compromised cloud accounts from 5–10/month to 2–3/quarter, preventing data loss and account takeovers, and significantly improving IT security team efficiency and incident response times.
