A Florida title company with zero email authentication was actively targeted by a business email compromise (BEC) scheme. The attackers were spoofing the firm's domain to send fraudulent wire transfer instructions to closing agents.
Our Solution
We deployed SPF, DKIM, and DMARC with a p=reject policy. This authenticated all legitimate email and automatically rejected spoofed messages at the gateway. We also configured monitoring alerts for any DMARC failures.
The Results
The client reported three separate spoofing attempts blocked in the first week alone. Estimated wire fraud exposure was $2.3M. Email delivery for legitimate clients was unaffected.

Frequently Asked Questions
How does DMARC stop wire fraud?
DMARC prevents attackers from spoofing your domain in emails. When a fraudulent email claiming to be from your firm arrives, DMARC instructs the receiving server to reject it before it reaches the inbox.
How long does DMARC deployment take?
Full deployment including SPF, DKIM, and DMARC typically takes 2-4 hours for most organizations.
Is DMARC enough to prevent BEC?
DMARC is the most effective single control against email spoofing-based BEC. Combined with employee training and verification procedures, it reduces risk by over 95%.
