No tool catches everything. But EFA is built to catch what actually causes losses — before you act.
It detects the patterns used in real-world fraud, at the moment it matters most. You should always verify independently.

Scammers use the same language and requests that legitimate people use. That's why EFA can warn you about an email that's completely real.
For example: You plan on wiring your mom money when she emails you saying she changed banks and gives you new wiring instructions. The email really could be from your mom, but EFA will warn you because the banking information changed.
That's exactly when you should verify. Call your mom using the number you already have and confirm the new banking information. If she confirms it, great — you can move forward. If she didn't send the email, the warning just stopped you from trusting fraudulent wiring instructions.
