Case Study: Armstrong Watson achieves rapid GDPR compliance and prevents misaddressed emails with Proofpoint

Proactively Protecting Customer Data

Armstrong Watson, a 150‑year‑old firm serving businesses across the North of England and Scotland, needed to protect sensitive client data and demonstrate GDPR compliance after identifying misaddressed emails as a key risk. With a loyal client base and a requirement that data be handled with discretion, the firm sought an intelligent, unobtrusive solution to prevent accidental data loss.

They deployed Tessian, using Guardian to block misdirected sensitive emails and Constructor to enforce outbound compliance rules; the platform was quick to install and includes logging and audit trails to prove diligence. The result was rapid GDPR gains, reduced risk of accidental disclosures, and added confidence from robust support and demonstrable organisational controls.
