Case Study: Choice Hotels achieves 36% reduction in email‑threat response and blocks advanced BEC with Abnormal AI

Connecting the World Through Technology and Hospitality

Choice Hotels, a global lodging franchisor protecting data for some 50 million loyalty members, faced targeted business email compromise and phishing that bypassed its two secure email gateways. To close that gap it turned to Abnormal AI, deploying Abnormal AI’s behavioral, AI-driven inbound email protection (including VendorBase™ and account takeover protections) to monitor Microsoft 365 mailboxes and stop socially engineered attacks and vendor compromise attempts.

Abnormal AI integrated in minutes and automated email triage, remediation, and search-and-respond so Choice’s SOC no longer had to manually clean inboxes. The deployment detected 120+ compromised vendors, stopped about 97 attacks per day, auto-remediated 100% of reported malicious phishing, and cut IT/SOC response efforts by 36% during peak season—freeing the team for threat hunting, intelligence sharing, and expanded employee training.
