Case Study: Campos Mello Advogados strengthens email security with Red Sift OnDMARC

CMA uses OnDMARC to lay down the law with email impersonation

Campos Mello Advogados (CMA), a Brazilian law firm working with DLA Piper, needed to secure a shared email environment as it moved more of its infrastructure to the cloud. To better detect and understand email impersonation beyond its own network boundary, CMA chose Red Sift’s OnDMARC.

Using Red Sift OnDMARC, CMA moved from DMARC reporting to quarantine in just one week and gained ongoing visibility into spoofing activity and supplier email protection. The results were strong: 5,677 unauthorized emails were detected and rejected in 30 days, attempted spoof attacks dropped 34% over six months, and the team now checks the domain status only weekly while progressing toward full protection.
