About Abnormal Security
AI that learns normal email behaviour and flags business-email-compromise + phishing. Used by Xerox, Procter & Gamble.
§ Pitch deck breakdown
How Abnormal Security would pitch themselves.
Target customer
F500 CISOs concerned about business email compromise — the single most damaging attack vector ($2.7B in 2022 FBI losses).
Problem they solve
Legacy email security (Proofpoint, Mimecast) catches malware-laden emails but misses today's threat — text-only social engineering (BEC, invoice fraud). $50B+ losses annually.
Key differentiator
Behavioural AI learns every user's communication patterns (Microsoft Graph + Google APIs). Catches identity-spoofing emails that have no malware or known IOCs — the entire BEC category.
Go-to-market strategy
Direct enterprise sales — replaces existing secure email gateway. Microsoft / Google ecosystem partnerships. Free 14-day risk-assessment proves ROI in real attacks caught.
