Forging a Stronger Defense: Why a Global Industrial Manufacturer Added Abnormal to Block What Proofpoint Couldn’t

A global industrial manufacturer blocked 3,232 missed attacks and saved 336 SOC hours per month by adding Abnormal to address gaps left by Proofpoint.

About the Customer

  • Industry: Aerospace and Industrial Manufacturing

  • Mailboxes: 12,200+

  • Email Infrastructure: Microsoft 365 E3 + Proofpoint Secure Email Gateway + Abnormal Human Behavior AI Platform

Customer Challenges: Concerns with Proofpoint's Secure Email Gateway

Abnormal transformed this aerospace and industrial components manufacturer’s overall security stack, offering more comprehensive protection and detecting advanced attacks that its Proofpoint SEG was failing to catch.

Positioned downstream in the mail flow, Abnormal detects only threats that bypass the gateway, capturing data that demonstrates the SEG’s shortcomings, including:

  • Detection Efficacy: During a three-month period, Abnormal detected 3,232 malicious messages that Proofpoint missed, including 2,082 credential phishing attacks and 303 invoice fraud attacks.

  • Workforce Productivity Impact: Over that same quarter, the company’s employees received more than 1.39 million graymail messages. Without an effective graymail filtering solution, these emails would clutter inboxes and require significant time for manual review and deletion.

  • SOC Productivity Impact: Within this timeframe, employees reported 5,034 emails for review. Since each email takes an average of 15 minutes to manually review, the SOC faced a potential loss of up to 419 hours of productivity each month without AI-powered automatic remediation.

Abnormal’s Solution: Better Protection for Defense in Depth

With Abnormal’s AI fortifying its security framework, this global manufacturing enterprise has reduced its risk, increased its efficiency, and boosted SOC productivity. Abnormal’s behavioral AI analyzes thousands of signals to baseline normal employee and vendor behavior and identifies high-risk anomalies with precision—protecting the organization from sophisticated attacks that traditional defenses like Proofpoint can miss.

  • Risk Avoidance: Based on the number of attacks identified for remediation, the average compromise rate Abnormal has observed for the customer’s industry segment*, and the average cost per incident**, the malicious emails missed by Proofpoint during the three-month period could have resulted in estimated potential annual losses of at least $5,800,000 if similar undetected attacks had continued at this pace.

  • Increased Inbox Efficiency: Abnormal’s AI automatically learned user preferences and identified unwanted emails; had this feature been operating in active mode, it could have saved employees up to 645 hours per month*** in a single quarter—data that led the customer to deploy the product across their email environment.

  • Improved SOC Productivity: Abnormal’s AI Security Mailbox fully automated the handling of user-reported emails. Because each email previously required an average of 15 minutes of SOC analyst time to review, this freed up an average of 335 SOC hours per month during the one-quarter observation period.

Because of Abnormal, this multi-national aerospace manufacturer can now feel more confident in its defense-in-depth security stack. Implementing the Abnormal Human Behavior AI Platform ensures that additional attacks are stopped, more employee time is saved, and the SOC team is freed to focus on higher-priority tasks.
