Case Study: Large K-12 Public School District achieves automated email protection and blocks thousands of attacks with Abnormal AI

School District Increases Automation and Email Protection with Abnormal

Large K-12 Public School, a large K-12 public school district serving 20,000+ employees and protecting 270,000+ mailboxes, struggled with frequent email attacks that bypassed Google Workspace’s native defenses after retiring their SEG. To stop phishing, vendor-compromise and BEC attacks while increasing visibility and reducing manual remediation, the district turned to Abnormal AI, deploying its Inbound Email Security, Email Account Takeover Protection, and Abuse Mailbox Automation.

Abnormal AI integrated with Google Workspace via API to provide cloud‑native detection, automated remediation and actionable attack visibility. In the first 90 days Abnormal AI detected 17,959 attacks, remediated 3,471 credential‑phishing attempts and stopped 170 invoice‑fraud/BEC campaigns—dramatically reducing malicious messages in inboxes, lowering manual workload and improving the district’s threat intelligence.
