Aperçu
Abnormal Security has emerged as the leader in AI-powered email security, protecting organizations from sophisticated phishing, business email compromise (BEC), and account takeover attacks that bypass traditional email gateways.
Using behavioral AI, Abnormal builds a baseline of normal communication patterns for every user and detects anomalies that indicate attacks—even when emails contain no malicious links or attachments.
The API-based architecture integrates seamlessly with Microsoft 365 and Google Workspace without requiring MX record changes or inline deployment.

Questions Fréquemment Posées
How does Abnormal Security deploy?
Abnormal uses API-based deployment connecting directly to Microsoft 365 or Google Workspace. No MX record changes or mail flow modifications required. Deployment typically takes less than 30 minutes with minimal IT involvement.
What is behavioral AI email security?
Instead of signature-based detection, Abnormal learns normal communication patterns for each user—who they email, writing style, timing, etc. It then detects anomalies indicating attacks, even when emails contain no malicious links or attachments.
Does Abnormal replace my existing email gateway?
Abnormal typically works alongside existing SEGs (like Proofpoint or Mimecast) to catch sophisticated attacks they miss. Some organizations eventually replace their SEG, but most deploy Abnormal as an additional layer focused on advanced threats.
How long is the learning period?
Abnormal begins protecting immediately but improves detection accuracy during the first 30 days as it learns organizational communication patterns. Most value is realized within the first week of deployment.
What is the false positive rate?
Abnormal has one of the lowest false positive rates in the industry, typically under 0.1%. The behavioral AI approach means it understands context and catches real attacks while minimizing legitimate email blocking.
Verdict Final
Abnormal Security sets the standard for AI email security. Its behavioral approach catches sophisticated attacks that bypass traditional gateways. Essential for organizations facing advanced email threats.
