The Problem

Small businesses lose thousands to fraud every day.

The FBI reported $16.6 billion in cybercrime losses in 2024 — a record high. Enterprise fraud tools cost $50,000+ a year and require IT teams. Most small business owners are left with nothing but gut instinct — and fraudsters know it.

📄
Invoice Redirect
A fraudster intercepts your vendor's invoice and changes the bank account. You pay the full amount — to the wrong person. Nearly impossible to recover.
👻
Phantom Vendors
A completely fake company set up to collect payments. Often runs for months undetected. The most underrated fraud type hitting small businesses.
📧
CEO Fraud
"Wire this immediately — keep it confidential." An email impersonating your boss. Designed to bypass your normal verification process. Devastatingly effective.
🔗
Typosquat Domains
mlcr0soft.com instead of microsoft.com. Character-by-character domain forgery designed to steal your credentials or redirect your payments.
