We already have a SEG. Why do we need this?

SEGs detect malware, bad URLs, and known-bad senders. BEC contains none of these. Abnormal detects behavioral anomalies — request type, timing, sender history, writing style — that signature-based tools architecturally cannot see. Deploys via API alongside your SEG with no mail flow changes.

How does Abnormal detect BEC with no malicious payload?

The platform builds per-identity behavioral baselines across 45,000+ signals. When an email deviates from established patterns — first-time payment request, atypical urgency, unfamiliar device — Abnormal detects attacker intent rather than known-bad indicators.

What happens if Abnormal blocks a legitimate email?

It happens — rarely. Near-zero false positive rates come from per-identity modeling, not broad pattern matching. Quarantined emails are easy to release, and Detection 360 provides full transparency on every decision.

Can Abnormal catch BEC from a compromised vendor's real account?

Yes. VendorBase tracks communication patterns with every supplier across more than 4,500 organizations. When a compromised vendor sends an unusual request — different tone, unexpected payment change, atypical timing — Abnormal flags it even though the sending account is legitimate.

Can this actually replace our SEG?

Yes. Over 70% of Abnormal customers operate without a third-party SEG, using Abnormal plus native Microsoft or Google security. Deployment takes minutes via API — no MX changes, no mail rerouting, no rules to write.

The Challenge

Your Gateway Is Missing the Attacks That Cost the Most

Wire Requests from Spoofed Executives Pass Authentication

Spoofed executive wire requests bypass SPF, DKIM, and DMARC because the attacker never touches the real domain.

Compromised Vendors Reply Inside Real Email Threads

Attackers hijack legitimate vendor accounts and reply mid-conversation with updated payment details.

Invoice Fraud Arrives Timed to Your Billing Cycles

Fraudulent invoices land during real payment windows, making them nearly indistinguishable from legitimate requests.

Payroll Diversion Mimics Legitimate HR Workflows

Fake employees request direct deposit changes using the same language and process your HR team expects.

Zero-Payload Emails Carry No Detectable Indicators

BEC emails contain no links, no attachments, and no malware — just text designed to manipulate.
