AP teams cannot reliably detect vendor email compromise fraud because standard email authentication (SPF, DKIM, DMARC) passes and the email originates from the vendor's real mailbox.
Existing email security and fraud detection tools rely on indicators like domain spoofing or failed authentication; they cannot detect fraud when the attacker has control of the legitimate vendor's email account and uses a real thread or invoice reference.
Workarounds Described
- Manually inspecting email domains for look-alike variations
- Reliance on SPF, DKIM, and DMARC checks to validate sender authenticity
Implied Software Gaps
- A fraud detection system that analyzes email content and metadata beyond authentication to identify compromised accounts
- An automated out-of-band verification tool that confirms payment change requests through a secondary secure channel
Vendor TrustGuard
Vendor TrustGuard detects vendor email compromise fraud by analyzing behavioral anomalies, payment pattern deviations, and cross-channel verification. It flags suspicious payment change requests even when email authentication passes and the request appears to come from a legitimate vendor account.
- Behavioral analytics on vendor communication patterns to spot anomalies in timing, language, or urgency
- Automated verification workflows that trigger out-of-band confirmation via registered phone or portal
- Integration with AP systems to track invoice and payment history for contextual risk scoring
- AI-driven detection of subtle inconsistencies in email threads, including reply-to email addresses and attachment metadata
