Case Study: Nuffield Health achieves 4-6x bandwidth boost and stronger patient-data security with Zscaler Internet Access

Zscaler™ Enables Better Security and User Access for Nuffield Health

Nuffield Health is a UK non‑profit healthcare provider operating 31 hospitals, 112 fitness and wellbeing clubs and serving about 22,000 users. As it prepared to roll out Office 365 and a new electronic health record (TrakCare), the IT team faced limited network capacity — single 30 MB MPLS links per site funneling traffic through two data centers — while 60% of traffic was already internet‑bound. The organization needed more bandwidth, resiliency and a way to secure internet traffic (including sensitive patient data) without significantly raising operating costs.

Nuffield Health deployed a Silver Peak SD‑WAN and Zscaler Internet Access for cloud‑delivered security and full SSL inspection, enabling local internet breakouts and user‑based policies across sites and devices. The combined solution delivered 4–6× more effective bandwidth, lower latency, faster access to internet apps, stronger protection for patient and guest traffic, seamless SD‑WAN integration and proactive vendor support — all without increasing operating expenses.
