Case Study: Large High-Profile Financial Services Company achieves minutes‑level incident response and eliminates false alarms with Proofpoint Threat Response

Large High-Profile Financial Services Company - Customer Case Study

A large, high‑profile financial services firm with mission‑critical systems and a heterogeneous security stack was facing an uptick in targeted cyberattacks. Its incident response team relied on manual, time‑consuming data gathering across multiple tools and vendors, leading to slow remediation, high false‑positive investigations and costly PC reimaging as incident volumes rose after deploying advanced detection.

The firm implemented Proofpoint Threat Response, which integrated with its SIEM, FireEye and multi‑vendor firewalls to collect contextual data (WHOIS, geolocation, AD mappings, PC IOCs), automate prioritization and push consistent, audited enforcement across devices. The result: response times dropped from hours or days to minutes or seconds, false alarms were largely eliminated, unnecessary PC reimaging fell by more than 80%, and the team regained capacity to focus on true threats.
