Abnormal Inbound Email Security

Abnormal Inbound Email Security is an API-based inbound threat prevention solution engineered to inspect, analyze, and block malicious inbound emails before they can deceive enterprise employees. Purpose-built to stop modern socially engineered cyber threats—including business email compromise, credential phishing, VIP impersonation, and vendor email compromise—it replaces legacy gateway inspection with AI-driven behavioral modeling.

Operating natively within Microsoft 365 and Google Workspace via direct cloud APIs, the solution analyzes incoming messages without altering DNS records or introducing delivery latency. It evaluates sender authenticity, domain age, relationship history, and email text semantics using natural language processing to identify anomalies that indicate fraud or spoofing. Common organizational use cases include blocking spear-phishing attacks targeting finance teams, preventing invoice fraud from compromised vendor accounts, neutralizing malicious URL redirects, and identifying weaponized attachments.

Featuring automated, real-time message quarantine and post-delivery protection, Abnormal Inbound Email Security ensures that malicious messages are eliminated from inboxes before users can interact with them. Security operations teams benefit from automated incident explanations that break down the exact reasons an email was flagged, eliminating manual rule tuning. The solution delivers superior inbound threat protection, reduces helpdesk phishing complaints by up to 95%, and provides dependable defense for enterprise communication channels.
