Email remains the #1 cause of breaches and #1 source of cybercrime losses to enterprises (Source: FBI Internet Crime Report). As attackers leverage generative AI and sophisticated social engineering, traditional security approaches that rely on threat intelligence and static rules are no longer sufficient. Organizations need a modern solution that deeply understands human behavior to protect against these evolving threats.
Abnormal Security delivers unprecedented protection through its AI-native platform for human behavior security. By leveraging a unique API-based architecture, Abnormal ingests 10x more behavioral signals than legacy solutions, enabling deep understanding of every employee and vendors behavior patterns. This foundation powers precise detection of anomalies and suspicious activities, stopping advanced attacks like business email compromise, supply chain fraud, account takeovers, lateral phishing, and AI-generated impersonation attempts before they can cause damage. For example, Abnormal detected and stopped a $13.5M payment fraud attempt where an attacker compromised an email account, created a look-alike domain, and sent a fraudulent invoice. Abnormals AI flagged anomalies such as the newly registered domain, suspicious email headers, and unusual language patterns, preventing the attack before any harm occurred.
Beyond superior detection, Abnormal transforms security operations through AI automation. The platforms AI Security Mailbox eliminates manual triage and investigation of reported emails, while automated remediation capabilities instantly remove threats across all mailboxes. This automation, combined with features like AI-generated security awareness training and intelligent graymail management, reduces SOC workload by 95% while improving employee productivity.
Deployed in 60 seconds via API, Abnormal integrates seamlessly with Microsoft 365 and Google Workspace without the need for professional services or ongoing admin overhead.

This listing uses a single pricing dimension based on the number of email mailboxes you place under management. You pay per mailbox, so your cost scales directly with how many mailboxes you protect. Add more mailboxes and your total rises in proportion; reduce them and it falls. Billing follows a contract term rather than hourly or usage-based metering. There are no separate tiers, instance sizes, or add-on charges to choose from. This keeps the structure straightforward: count your mailboxes, and that count sets your price.
Top-of-mind questions for buyers
What counts as one mailbox for billing?
A mailbox is a single email account placed under management, such as one user's inbox. Each account you enroll counts as one unit. Shared or group mailboxes each count separately when managed. The total number of managed mailboxes sets your charge.
How does my cost change if I add or remove mailboxes during the term?
Your cost scales with the count of mailboxes under management. Adding mailboxes raises your total in proportion; removing them lowers it. There are no tiers or thresholds that shift pricing. The count of managed mailboxes is the only figure that drives the charge.
Does this listing cover only email, or other security areas too?
This listing prices email security, which stops attacks like business email compromise, phishing, and account takeover. The vendor's platform also offers identity, AI, and insider threat protection. Those areas are separate and are not part of this per-mailbox email security charge.
