Abnormal AI sells behavioral-AI email and account protection that connects to Microsoft 365 and Google Workspace through APIs. It has the markers of a category leader: a Leader placement in the 2024 Gartner Magic Quadrant for Email Security Platforms and the 2025 Forrester Wave, more than $200 million in recurring revenue, and more than 4,500 customers including a quarter of the Fortune 500. It has also earned public-sector credentials, including FedRAMP authorization, that competitors must independently earn. The catch is that Abnormal runs on top of the mailboxes Microsoft and Google own, and those two sell competing email protection. It is most defensible in regulated and government accounts, and most exposed where a buyer treats email security as a feature of the mailbox.

This site is an experimental research aid created by Zeltser Security Corp. All its data gathering and analysis was performed autonomously without human review, and it can contain errors of fact, interpretation, and judgment that a human reviewer might catch.
The analyses are statements of opinion, not statements of fact. Machine analysis produced the scores, summaries, and matrix placements by weighing the public sources each page cites, and reasonable people can weigh the same sources differently. Where a page states a fact, it cites the public source and the date it was checked, and the statement is only as accurate as that source. Unless a profile expressly says otherwise, the analysis involves no hands-on testing and no independent validation of any company's products or services.
