Case Study: Fortune 200 Asset Management Company achieves zero compromised accounts and stops 3,500+ email attacks with Abnormal AI

Fortune 200 Asset Management Company Protects Customer Wealth from Email Threats

Fortune 200 Asset Management Company, a leading insurance and asset manager, faced thousands of credential-phishing attacks and multiple account takeovers targeting its Microsoft 365 environment. Despite existing secure email gateways (Cisco ESA/IronPort, FireEye) and MFA, the firm needed additional email-layer protection and chose Abnormal AI’s email security solution to gain visibility and stop advanced, socially engineered attacks.

Abnormal AI was implemented in about 15 minutes and immediately provided visibility and remediation, finding a compromised account within the first day. Over a 90‑day period Abnormal AI blocked thousands of attacks — including 3,507 phishing attempts, 193 BEC campaigns, 136 malware incidents, 220 account takeovers and 802 fraud attempts — protecting 20,800+ mailboxes and helping the company maintain zero compromised accounts in the past two years.
