Raising the Bar: How Abnormal Delivered What Proofpoint Couldn’t for a Fortune 500 Insurance Leader

• Industry: F500 Insurance Provider

• Mailboxes: 64,800+

• Email Infrastructure: Microsoft 365 E3 and E5 + Proofpoint Secure Email Gateway + Abnormal Human Behavior AI Platform

Abnormal transformed this Fortune 500 insurance provider’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 27,847 malicious messages that Proofpoint missed, including 17,409 credential phishing attacks and 173 business email compromise attacks. Abnormal also detected 28 account takeover cases where email accounts had been successfully compromised.

• Workforce Productivity Impact:

  • Over that same quarter, the company’s employees received more than 14.3 million graymail messages. Without an effective graymail filtering solution, these emails would have cluttered inboxes and required significant time for manual deletion.

• SOC Productivity Impact:

  • Within this timeframe, employees reported 25,817 emails for review. Since each email takes an average of 15 minutes to manually review, the SOC faced a potential loss of up to 2,151 hours of productivity each month without AI-powered automatic remediation.

With Abnormal’s AI fortifying its security framework, this insurance leader 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 identify 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 total annual losses of more than $4,260,000 if similar undetected attacks had continued at this pace.

• Increased Inbox Efficiency:

  • Abnormal’s AI automatically learned user preferences and decluttered employee inboxes; this functionality saved employees up to 6,653 hours per month in a single quarter.

• 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 1,721 SOC hours per month during the one-quarter observation period—freeing up the capacity of approximately 10.5 additional full-time employees.

Because of Abnormal, this insurance provider 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.
