How does Abnormal deploy across thousands of retail locations without disrupting mail flow?

One API integration at corporate covers every mailbox across every location. No MX record changes, no per-store configuration, no mail rerouting. Most retail customers are live in under five minutes.

Can Abnormal detect vendor compromise when the email comes from a legitimate domain?

Yes. VendorBase tracks behavioral patterns for every vendor across our entire customer base. When a vendor's communication deviates from baseline — even from their real domain with valid authentication — Abnormal flags it before AP processes the payment.

What about internal email between stores and corporate that our gateway can't see?

Abnormal's API integration sees all internal-to-internal email. When a compromised store account sends lateral phishing to corporate finance, Abnormal detects the behavioral anomaly and remediates automatically. Gateways are architecturally blind to this traffic.

What happens if Abnormal blocks a legitimate vendor email?

It happens — rarely. Our false positive rate is below 0.01%. When it does occur, quarantined emails are easy to release with one click. We'd rather flag a borderline message and give you a simple override than let a $600K invoice fraud through.

Does this work for franchise operations with separate M365 tenants?

Yes. Abnormal supports multi-tenant deployment. Each franchise tenant connects via its own API integration, and behavioral intelligence is shared across the organization. No per-tenant gateway configuration required.

Retail

Across every location and vendor, Abnormal learns what normal looks like — and stops what doesn't.

Your team stops vendor invoice fraud and credential phishing across thousands of locations — deployed via API in minutes, no MX changes.

The Challenge

Your Gateway Delivers the Invoice That Drains the Account

Vendor Payment Redirects Inside Legitimate Email Threads

Attackers compromise a supplier's mailbox and reply within an existing invoice thread with updated bank details.

Gift Card Requests from Spoofed Executives during Peak Season

During holiday surges, attackers impersonate store directors or regional VPs requesting bulk gift card purchases from seasonal staff.

Compromised Store Manager Accounts Sending Lateral Phishing

High employee turnover means frequent credential resets and weaker password hygiene at store level.

Multi-Property Impersonation Targeting Shared Services and AP

Attackers spoof property GMs or regional directors and email shared services for vendor onboarding or payroll changes.

How It Works

Behavioral AI for Retail

Know the Moment a Vendor Is Compromised

VendorBase tracks communication patterns for every supplier across Abnormal's entire customer base. When a vendor account is compromised anywhere — even at another retailer — that intelligence protects your AP team immediately. Your gateway has never seen the infrastructure.

Catch the Attacks That Carry Zero Indicators

Behavioral AI analyzes 45,000+ signals per identity to detect anomalies in tone, timing, and request patterns — even when the email contains no malicious payload. A text-only invoice redirect from a legitimate domain gets flagged because the request deviates from established vendor behavior.

Stop Compromised Insiders Before They Reach Finance

API-native architecture sees internal-to-internal email that gateways structurally cannot access. When a store manager's account is compromised and sends lateral phishing to corporate AP, Abnormal detects the behavioral deviation and remediates in seconds — across every tenant, every location.

Our Impact

What Retail Leaders Are Saying About Abnormal AI

“When Abnormal found threats our SEG wasn’t detecting, we had to make a change, and Abnormal tying into Microsoft via API was gold for us. Leveraging Microsoft and Abnormal moves us away from the traditional SEG, eliminates that cost, and improves our security.”

Jonny Concannon

Information Security Manager, Boohoo

“The Proof of Value quickly delivered impressive results. After Abnormal trained on our environment, I saw how high fidelity the alerts were, compared to the other solutions and our own digging.”
