Case Study: Johnson Controls enables secure, global remote work for 25,000 users in two weeks with Zscaler Zero Trust Exchange

Johnson Controls Secures Business and IT Digital Transformation with the Zscaler Zero Trust Exchange

Johnson Controls, a global leader in building products and services with about 105,000 employees across 2,000 locations, needed to rapidly support digital transformation and enable work-from-anywhere during the COVID-19 pandemic. With an existing VPN that scaled to only 10,000 users, supply-chain delays for hardware and travel restrictions made traditional VPN expansion impractical, risking continuity for mission-critical life‑safety and customer services.

Johnson Controls accelerated its move to the Zscaler Zero Trust Exchange (ZIA and ZPA), completing a proof-of-value and rolling out ZPA and the Z App to 25,000 users in two weeks using a phased approach and joint tiger team. The deployment improved latency and user satisfaction versus VPNs, provided a single pane of glass for security operations, freed teams to focus on optimization and automation, dramatically increased global visibility and agility, and delivered at-a-glance risk assessment via the Executive Insights app—keeping the business running smoothly.
