This round was led by Boston-based investment firm Wellington Management, with participation from Greylock Partners, Menlo Ventures, and Insight Partners, among others. Additionally, CrowdStrike's Falcon Fund also supported Abnormal Security. Through this Series D funding, Abnormal Security's total funding has reached $546 million, with a valuation of $5.1 billion.

The company plans to use the funds for product investment, particularly enhancing the capabilities of its autonomous AI decision-making system and developing new features. Abnormal Security also aims to expand its product line, extending its service scope from email protection to other areas of the cloud environment. To strengthen its business expansion in the Asia-Pacific and European regions, they are actively pursuing FedRAMP certification to provide solutions to the U.S. federal government.

Evan Reiser, Co-founder and CEO of Abnormal Security, stated: "We relentlessly pursue our mission to protect humans through AI and have earned the trust of our customers by providing superior human behavior security products." He noted that this funding will further help invest in the human behavior AI platform, thereby protecting more people and helping customers accelerate the advancement of their AI projects.

Abnormal's security platform utilizes machine learning technology to detect intrusion attacks and compromised accounts, especially in emails and associated applications. Its anomaly detection engine analyzes email content to understand human behavior, effectively identifying social engineering attacks targeting employees. For example, their email abuse tool can automatically scan suspicious email headers and content, flagging them as safe or potentially malicious.

It is reported that Abnormal Security's service demand is extremely strong, with annual recurring revenue growing by 100%. Currently, 17% of the Fortune 500 companies are using their services, with a total of over 2,400 customers. Rob Mazzoni, a late-stage growth investor at W Management, said: "The early success of Abnormal Security is impressive, and the platform is well-equipped to address today's cybersecurity challenges centered around human behavior and identity."
