First-Rate Care, First-Rate Security: How Abnormal Overcame Proofpoint’s Shortcomings for a Leading Hospital System

• Industry: Healthcare

• Mailboxes: 51,800+

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

Abnormal transformed this award-winning hospital system’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 2,181 malicious messages that Proofpoint missed, including 1,177 credential phishing attacks. Abnormal also detected 21 account takeover cases where email accounts had been successfully compromised.

• SOC Productivity Impact: Within this timeframe, employees reported 1,629 emails for review. Since each email takes an average of 15 minutes to manually review, the SOC faced a potential loss of up to 135 hours of productivity each month without AI-powered automatic remediation.

With Abnormal’s AI fortifying its security framework, this leading healthcare provider has reduced its risk 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 more than $1,000,000 if similar undetected attacks had continued at this pace.

• 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 108 SOC hours per month during the one-quarter observation period.

Because of Abnormal, this major academic medical center can now feel more confident in its defense-in-depth security stack. Implementing the Abnormal Human Behavior AI Platform additional attacks are stopped and the SOC team is freed to focus on higher-priority tasks.
