Case Study: Premier Asset Management prevents accidental and unauthorized email data loss with Proofpoint

Protecting Against Data Loss Caused by Human Error

Premier Asset Management, a fast‑growing UK retail asset manager focused on delivering long‑term investment outcomes, faced the challenge of controlling and monitoring the movement of sensitive email data. Manual checks for personal addresses were laborious and limited, leaving the firm exposed to both accidental misdirected emails and deliberate data exfiltration.

Tessian deployed its machine‑intelligent Human Layer Security platform, using the Relationship Graph plus Guardian and Enforcer filters to analyze outbound mail in real time, detect anomalous behavior, and automatically block, trace or restrict sensitive messages to personal or unauthorized accounts. The result: a transformed, more comprehensive security protocol that reduced manual effort and effectively prevented both accidental and malicious email data loss.
