Abnormal Security, a San Francisco-based AI-native human behavior security company, has closed its Series D funding round, raising $250 million and achieving a valuation of $5.1 billion.
Wellington Management led the round, with participation from existing investors Greylock Partners, Menlo Ventures, Insight Partners, and CrowdStrike Falcon Fund.
The company plans to use the funds to expand operations and enhance development efforts.
Under the leadership of CEO Evan Reiser, Abnormal Security offers a security platform that uses machine learning to stop sophisticated inbound attacks and detect compromised accounts across email and connected applications. Its anomaly detection engine analyzes human behavior and evaluates the risk of every cloud email event to identify and prevent socially-engineered attacks targeting human vulnerabilities.
Abnormal can be deployed via API integration for Microsoft 365 or Google Workspace, providing immediate value. Additional protection is available for applications such as Slack, Workday, Salesforce, ServiceNow, Zoom, Amazon Web Services, and more.
This investment comes after significant growth for Abnormal Security, which has seen over 100% year-over-year increases in annual recurring revenue, recently surpassing $200 million. More than 2,400 organizations, including 17% of the Fortune 500, use Abnormal’s platform to protect their employees. Since last August, the company has expanded into Europe, Asia, and Australia and is working towards FedRAMP compliance.
