Case Study: DAC Beachcroft LLP achieves rapid reduction in misdirected emails and stronger client-data protection with Proofpoint

Keeping Sensitive Client Data Safe

DAC Beachcroft LLP, a global legal firm with about 2,500 employees across Europe, Asia Pacific and Latin America, needed to tighten protection of highly sensitive client data and reduce the risk of human error—particularly misdirected or unauthorized emails—while allowing lawyers to work flexibly across devices and minimizing disruption during deployment.

They adopted Tessian’s machine-intelligent email security platform, which uses stateful machine learning to detect abnormal email patterns and automatically block or flag risky messages without requiring user behavior changes. The solution was quick to install, easy for busy staff to use, and delivered measurable results—significantly reducing email-related risk within four weeks and providing immediate protection against potential data breaches.
