Case Study: Department for Business, Energy & Industrial Strategy (BEIS) secures next‑gen apps, blocks 400K threats/month and saves $500K with Zscaler Zero Trust Exchange

BEIS Secures Its Next-Gen Government App Platform

The UK Department for Business, Energy and Industrial Strategy (BEIS) — a federal agency supporting 43 public bodies and more than 12,000 users — needed to modernize security during a major merger and cloud-first transformation. BEIS moved away from a legacy castle-and-moat model to protect data, enable a new cloud networking platform (Cirrus), and meet broader government goals around agility and sustainability.

BEIS adopted the Zscaler Zero Trust Exchange (ZIA and ZPA), integrating with AWS and its SIEM to provide VPN-free, direct-to-cloud security. The deployment eliminated costly MPLS (saving about $500K annually), increased platform users 70% without extra overhead, blocked ~400K threats and prevented 10M policy violations monthly, secured billions of SaaS/private transactions, and accelerated application rollouts from months or years to days or weeks while supporting the department’s net-zero objectives.
