Stop Invoice Fraud
Before Payments Leave
Attackers register domains that look identical to your trusted vendors — then send convincing invoices with updated banking details. By the time finance discovers the fraud, the money is gone.
DefendDomain detects fake vendor domains the moment they appear, alerting your team before a single fraudulent invoice is processed.

Real threats targeting your domainExpert consultation, not a sales pitchNo obligation
The FBI reported $2.9 billion in BEC losses in 2023 alone, with the average incident costing $137,000. And 79% of organisations experienced payment fraud in 2024.
We catch the fake vendor domains before fraudulent invoices are ever sent.
DefendDomain monitors for lookalike domains mimicking your company and your critical vendors. When an attacker registers a domain designed to impersonate a trusted supplier, your finance and security teams are alerted immediately — with full evidence to verify the threat.
Understanding the threat
What Is Vendor Invoice Fraud?
Vendor invoice fraud — also called supplier email compromise or mandate fraud — occurs when attackers impersonate a trusted vendor to redirect payments. They register a lookalike domain, send a convincing email requesting updated banking details, and wait for finance to process the change.
Internal BEC
Attackers spoof an executive's email to request urgent wire transfers. Caught by DMARC when properly configured.
Mitigated by DMARC and email authentication.
Inbound Payment Requests
Fraudulent payment requests sent to your accounts payable team from external senders.
Partially caught by email gateways.
Vendor Domain Impersonation
Attackers register domains nearly identical to your trusted vendors (e.g., supp1ier-corp.com vs supplier-corp.com) and send invoices with updated banking details that bypass all email filters.
We detect fake vendor domains the moment they register, before any fraudulent invoice is sent.

Common assumptions
Why Your Payment Controls Still Have Gaps
Dual authorisation, callback procedures, and trained finance teams are essential. But sophisticated attackers have adapted to every one of these controls.
"We verify payment changes by phone"
Attackers anticipate callback procedures. They register lookalike domains, set up convincing email threads over days or weeks, and time their requests for high-pressure moments — month-end, quarter-close, or during a key project. Under time pressure, callbacks get skipped or directed to the wrong number.
Why verification alone isn't enough"Dual authorisation protects us"
Dual authorisation ensures two people approve a payment — but if both approvers see the same convincing email from what appears to be a trusted vendor’s domain, they’ll both approve it. The control validates process, not authenticity of the request.
Gaps in dual authorisation"Our bank will reverse fraudulent transfers"
Banks can only reverse transfers that haven’t been withdrawn. Attackers move stolen funds within hours, often through multiple accounts across jurisdictions. In 2024, less than a quarter of organisations recovered 75% or more of funds lost to payment fraud (AFP Survey).
Why recovery is unreliable"We trust our established vendors"
That trust is exactly what attackers exploit. Long-standing vendor relationships create familiarity that makes finance teams less likely to question routine-looking invoices. Attackers study your vendor relationships through LinkedIn, press releases, and data breaches to craft perfect impersonations.
