Case Study: Ingersoll Rand stops AI-driven email attacks and saves $250K/year with Abnormal AI

Ingersoll Rand Unlocks the Potential of Behavioral AI Security and Automation

Ingersoll Rand, a global industrial machinery manufacturer with 32,000+ protected mailboxes, was facing increasingly precise AI-driven email attacks that were evading Microsoft 365 and their secure email gateway (SEG), putting connected operational technology (OT) and customers at risk. To stop business email compromise, credential phishing, malicious attachments and polymorphic attacks while reducing manual effort, Ingersoll Rand selected Abnormal AI for a zero‑maintenance, API-based layer that uses human behavior AI.

Abnormal AI deployed inbound email security, Account Takeover Protection, an AI Security Mailbox and AI automation, integrating with CrowdStrike to enrich detections and responses. The solution blocked sophisticated attacks, protected all accounts in under 15 minutes, saved $250K per year in SOC automation, prevented a $50K BEC loss, and reclaimed 2,459 employee and VIP hours on graymail in 30 days, allowing the SOC to focus on higher‑risk analysis.
