Case Study: Webb Henderson achieves stronger client data protection and a customer-first email security culture with Proofpoint

Defining Customer-First Culture with Email Security

Webb Henderson is a specialist legal and regulatory advisory firm with offices in Sydney and Auckland that handles highly sensitive, unstructured client data. Faced with rising client demands for strong supply-chain security and the limitations of rules-based DLP for protecting email, the firm needed a discreet, user-friendly solution to prevent accidental data exfiltration without disrupting lawyers’ workflows.

Webb Henderson deployed Tessian’s machine-learning Human Layer Security—including Guardian and Enforcer filters and Constructor—to detect and block risky email behavior in real time. The result is seamless integration into a layered security stack with low false positives, improved visibility and control over email risks, reduced human error, and an ongoing partnership to keep client data secure.
