Case Study: UST Global achieves secure, high-performance, appliance-free internet and reduced costs with Zscaler

UST Global enables a secure, high-performance user experience

UST Global, a global digital technology services firm with about 18,000 users, was struggling with a fragmented, appliance-based web security model that drove high hardware and licensing costs, frequent downtime, and inconsistent policy enforcement across offices and remote workers. Managing and upgrading distributed proxies consumed IT resources and made it difficult to deploy consistent security for new locations and a 7,000-person remote workforce.

UST Global migrated to Zscaler Internet Access, removing on‑premises appliances and routing all traffic to a cloud security stack (cloud firewall, full SSL inspection, bandwidth control, centralized logging and SIEM integration). The cloud deployment unified policy enforcement, improved threat detection and mobility protection, and reduced overhead—eliminating large CAPEX and cutting web security costs (about 65% CAPEX savings and a 40% reduction in web security spend)—while freeing IT to focus on strategic initiatives.
