Case Study: U.S. Defense and Aerospace–Based Company achieves 15–20 minute insider-threat investigations with Proofpoint

Defense Contractor Hones Monitoring on Insider Threats With Proofpoint

A U.S.-based defense and aerospace contractor that serves government and commercial customers faced a growing insider‑risk problem: it handles vast amounts of sensitive intellectual property and needed to prevent exfiltration (including via removable media and potential nation‑state actors), enrich alerts from disparate security tools, speed investigations, and meet strict regulatory requirements. Its legacy data‑loss tool was granular but hard to manage and hurt performance and user experience.

After a six‑week pilot, the company deployed Proofpoint Insider Threat Management to provide a single source of truth across 30,000+ endpoints. The platform’s easy‑to‑read timelines and search capabilities gave rapid context to alerts, cut investigation time from days to about 15–20 minutes on average, reduced false positives, helped mitigate insider threats before they spread, and made it easier to explain incidents to legal, HR, and other stakeholders.
