Case Study: Mace Reinforces prevents vendor email compromise and saves 160 hours/month with Abnormal AI

Mace Reinforces Trust, Builds Efficiency with Behavioural AI-Based Email Security

Mace Reinforces, a global construction and consultancy firm with high‑value, confidential projects, was facing a surge in vendor email compromise and advanced email threats that evaded signature‑based defenses and consumed significant security resources. To shore up protection and preserve client trust, Mace Reinforces turned to Abnormal AI’s behavioural, language‑based inbound email security and email account takeover protection.

Abnormal AI integrated its AI/ML solution with Microsoft 365 to automatically detect deviations in sender intent and language, block invoice fraud and vendor compromise, and provide shareable intelligence for supply‑chain remediation. The deployment saved about 160 security‑team hours in one month (equivalent to a full‑time employee), identified 113 high‑risk vendors on integration, recorded zero missed attacks or false positives in 30 days, and prevented hundreds of thousands of pounds in immediate risk.
