Case Study: MGM Resorts International achieves cloud-native zero‑trust security and 50% device efficiency gains with Zscaler

MGM Resorts International Doubles Down on a Cloud Native Zero Trust Architecture

MGM Resorts International, a global gaming and hospitality leader with 31 resorts and about 70,000 employees, faced rising risk from a traditional "castle-and-moat" security model. Legacy VPN gateways created traffic bottlenecks and poor user experience, while older tooling gave limited insight into browsing and data activity—raising lateral movement and compromise exposure.

MGM replaced VPNs with a cloud-native Zero Trust architecture using Zscaler (ZIA, ZPA, ZDX, DLP and Deception), rapidly implementing zero trust segmentation, private access, digital experience monitoring, and data loss protection. The deployment delivered immediate value—blocking 275K+ threats per month, improving device efficiency by over 50%, speeding connectivity, and strengthening the company’s security posture while enabling a cloud-first business approach.
