Case Study: Landmark Group prevents $1M in vendor fraud and saves 1,320 SOC hours with Abnormal AI

Landmark Group Transforms Its Email Security Posture with Human Behaviour AI

Landmark Group, a Dubai‑based omnichannel retail conglomerate with 55,000 employees and 12,500+ protected mailboxes, faced advanced phishing, vendor email compromise and invoice‑fraud attacks that were evading its existing email hygiene tools and wasting SOC time. To modernise and scale its email security, Landmark Group selected Abnormal AI, deploying its human behaviour AI via Inbound Email Security, Account Takeover Protection and the AI Security Mailbox.

Abnormal AI’s behaviour‑based detection and automation evaluated identity and context to stop threats before they reached inboxes, integrating quickly via a one‑click/API‑based setup in Azure. The solution identified 78 financial fraud attacks during proof‑of‑value, now blocks about 12,000 advanced email attacks per week on average, prevented US$1M in VEC losses in 12 months, and saved roughly 1,320 SOC hours and ~240K AED per year through automation and efficiency gains.
