Abnormal is a cloud-native email security solution that uses behavioral AI to provide protection against advanced email threats such as social engineering, malware, and account compromise. The platform combines inbound email security and account takeover protection to ensure that user inboxes are secured against inbound and internal email threats, providing more comprehensive protection than a traditional secure email gateway (SEG).
To protect against inbound email threats, Abnormal’s Inbound Email Protection creates a risk profile for all inbound communications. Safe emails are delivered securely to the inbox, spam is delivered to the user’s “junk” folder, and emails that are deliverable but may be suspicious are delivered with a contextual warning banner that notifies the end user to beware of its contents. Abnormal also rewrites the URLs of any potentially malicious emails, preventing users from being redirected to phishing websites.
Abnormal’s Account Takeover Protection features an AI engine that analyzes all emails against over 45,000 indicators of compromise—such as login frequency, location and communication patterns—to detect anomalies in the sender’s behavior, helping to quickly identify and mitigate internal and vendor account compromise. Compromised accounts are automatically disarmed by logging users out of active sessions and blocking their access, reducing the spread of an attack.
Abnormal Security’s platform deploys natively in the cloud and offers seamless Google Workspace and Microsoft 365 integration via API, meaning that users benefit from Abnormal’s protection without having to turn off the in-built security features offered by Microsoft Defender. We recommend Abnormal as a powerful email security platform for organizations of all sizes, and particularly those using a Microsoft email client.
