Case Study: Coastal Housing Group achieves protection against spear-phishing and accidental data loss with Proofpoint

Securing a Leading Social Housing Provider

Coastal Housing Group is a not‑for‑profit social housing provider in South Wales that manages large volumes of sensitive resident and commercial data. With a growing mobile workforce and increasing data leaving its controlled network, the IT team sought machine‑learning email protection to strengthen security and support GDPR obligations.

Tessian integrated quickly into Coastal’s existing stack, deploying Guardian to prevent accidental data loss and Defender to block inbound spear‑phishing. The solution runs quietly with low false positives, provides contextual warnings that reduce human error, bolstered the organisation’s GDPR posture, and reassured staff that sensitive information and systems are better protected.
