Case Study: Fortune 100 Manufacturing Company thwarts business email compromise and prevents millions in invoice fraud with Proofpoint

Fortune 100 Manufacturing Company Controls Business Email Compromise With Proofpoint

This Fortune 100 manufacturing company, with roughly 90 sites across about 70 countries and a supply chain of thousands of vendors, faced rising business email compromise (BEC) and supplier-impersonation attacks. The organization needed better global visibility into vendor interactions, faster response to zero-day threats, and stronger alignment between security, procurement and finance teams to prevent fraud and protect intellectual property.

The company deployed Proofpoint’s Threat Protection Platform—including Email Protection, Targeted Attack Protection, Threat Response Auto‑Pull, and Security Awareness Training—using ML/AI-powered detection and automated response to spot impostor threats early and reduce manual work. The solution stopped multiple supplier invoicing fraud attempts (including $350K and $80K attempts), delivered a 99.94% protection level, cut investigative effort to about one‑third of an FTE, improved phishing click rates to industry‑best levels (≤15 clicks per 100,000), and provided executive‑ready reporting.
