Case Study: Leading Information Technology Company achieves automated email and supplier threat protection with Proofpoint

Leading Energy Provider Safeguards Communications, Vendors and Customers With Proofpoint

This leading U.S. energy provider serving nine million residential and commercial customers faced rising compromise of vendor and customer networks, increasing business email compromise (BEC) and domain impersonation attacks, and the need to protect critical infrastructure while optimizing limited staff resources. The organization needed an automated, efficient way to detect and mitigate email-based threats across its complex supplier and partner ecosystem.

The company deployed a multilayered Proofpoint solution—Email Protection, Targeted Attack Protection (TAP) with Supplier Threat Protection, Email Fraud Defense (EFD), and Security Awareness—to strengthen email authentication, detect compromised supplier accounts with behavioral AI, and monitor lookalike domains. The result: automated, prioritized threat detection that improved visibility, accelerated containment and remediation, reduced BEC risk, freed up staff time, and strengthened vendor and customer relationships while keeping infrastructure secure and compliant.
