Case Study: Union Assurance PLC achieves 40% cost reduction and secures a 100% mobile workforce with Zscaler

Union Assurance PLC Secures Mobile Workforce and Cuts Network Costs by 40% with Zscaler

Union Assurance PLC, Sri Lanka’s premier life insurer (600 employees, 289K+ customers), needed to support hybrid work while addressing slow remote access, growing risk from distributed data, and the cost and complexity of a legacy perimeter-based WAN and VPN architecture. The company needed better visibility for compliance and a way to protect sensitive customer data without backhauling traffic through data centers.

Union implemented Zscaler’s cloud-native Zero Trust Exchange—deploying ZIA, ZPA, ZDX and Data Protection—to connect users directly to apps with least-privilege access, inspect encrypted traffic, and monitor digital experience. The solution secured a 100% mobile workforce, improved performance and productivity, strengthened compliance and data protection, blocked thousands of threats, and eliminated the MPLS WAN and on‑prem appliances, cutting network and security costs by about 40%.
