Case Study: Laya Healthcare reduces human email errors and IT overhead with Proofpoint

Laya Healthcare - Customer Case Study

Laya healthcare, a member‑centric Irish health insurer serving roughly 580,000 customers, faced a critical email security challenge: routine productivity features like autocomplete were contributing to misdirected emails and putting sensitive patient data at risk. Their existing DLP tools caught many mistakes but lacked the intelligence to learn from user behavior, and the IT team needed a solution that would eliminate human error without adding significant administrative overhead.

Tessian deployed its Guardian product, using machine learning to distinguish normal business email patterns and unobtrusively flag risky messages to the sender. The solution required minimal “care and feeding” from IT, freeing the security team for higher‑value work while reducing the likelihood of accidental data loss and providing a more scalable, future‑proof approach to email security.
