Case Study: Aircastle achieves rapid insider-threat detection and 15–20 minute investigations with Proofpoint Insider Threat Management (Proofpoint)

Grounding Insider Threats with Proofpoint Insider Threat Management (ITM)

Aircastle, a publicly traded commercial aircraft leasing company, needed to protect sensitive financial and M&A information, meet SOX and privacy requirements across international offices, and do so with a lean IT team. Traditional endpoint DLP solutions proved time-consuming to manage, overly file-focused, and prone to crashes, leaving the company exposed and straining resources.

After a successful proof of concept, Aircastle deployed Proofpoint Insider Threat Management (ITM) to gain real-time visibility into user activity. ITM delivers rapid, relevant alerts, fine‑grained privacy controls, and fast investigations—reducing incident investigations from days to about 15–20 minutes—while helping meet SOX obligations, improve NIST security posture, increase employee reporting of out‑of‑policy behavior, and better protect critical business data.
