Case Study: Pegasystems achieves 100% SEG cost savings and stops executive impersonation attacks with Abnormal AI

Pegasystems Displaces SEG for Better Email Security at a Lower Cost

Pegasystems, a global leader in low-code AI-powered decisioning and workflow automation, faced hundreds of VIP impersonation emails bypassing their SEG and Microsoft Defender, plus nearly 250,000 spam/graymail messages hitting employee inboxes each month. The Corporate Security Operations team was spending roughly 60 hours per week on manual investigation and remediation, so Pegasystems evaluated API-based solutions and chose Abnormal AI’s inbound email security stack (Inbound Email Security, Email Account Takeover Protection, Abuse Mailbox Automation, and Email Productivity) to avoid disrupting their Microsoft 365 environment.

Abnormal AI’s behavioral AI was deployed to baseline normal user behavior, stop impersonation attacks, automate abuse mailbox workflows, and tailor graymail filtering to individual preferences. As a result, Pegasystems displaced its SEG (eliminating that licensing cost), eliminated executive impersonation attacks, filtered ~250K graymail messages monthly, reduced the security team’s email workload from ~60 hours/week to about 5 hours/week, reported zero missed attacks/false positives last month, and saved 925+ hours monthly overall.
