Case Study: Rightmove achieves enterprise email security and prevents accidental data loss with Proofpoint

Preventing Data Exfiltration at a FTSE 100 Tech Company

Rightmove, the UK’s largest online property portal and a FTSE 100 company, faced the challenge of preventing accidental data loss and unauthorized email activity across all systems and devices without disrupting staff or customers. With 530 people to protect, Head of Customer Experience David Cray sought a seamless outgoing-email solution that would work organization-wide.

Rightmove quickly deployed Tessian’s Guardian and Enforcer across its UK teams, using machine learning to provide fast, low‑friction protection. Guardian prevents misdirected emails and Enforcer blocks sensitive messages to unauthorized accounts, delivering prompt threat detection, minimal disruption to workflows, and stronger overall email security.
