Case Study: Charity: Water achieves rapid, automated defense against spear‑phishing and email fraud with GreatHorn

Charity Water - Customer Case Study

Charity: Water, a global nonprofit that directs 100% of public donations to clean-water projects, faced a high risk of targeted email attacks: their staff directory is public, they process frequent financial transactions, and their team is distributed worldwide. To protect donors, operations, and reputation from spear phishing, business email compromise, and impersonation attempts, Charity: Water turned to GreatHorn’s cloud-native Inbound Email Security and Policy Engine.

GreatHorn deployed rapidly and integrated at the platform level, becoming operational in minutes and providing 24/7/365 automated, policy-driven remediation that filters threats in real time without disrupting mail flow. By removing malicious messages instantly, surfacing impersonation and fraudulent wire-transfer attempts, and reducing investigative noise, GreatHorn gave Charity: Water continuous protection and operational confidence while preserving donation-processing workflows.
