Zscaler, Inc. extends the AI-powered Zscaler Zero Trust Exchange?? platform with the launch of Zscaler Cellular. This easy to install innovation enables Zero Trust communication for IoT and OT devices using only a cellular SIM card--eliminating the need for additional software or ineffective VPN connections.

Zscaler Cellular delivers resilient connectivity by ensuring IoT/OT devices automatically connect to any cellular network globally, while providing zero attack surface by isolating each device on its own private island, with all connections securely routed through the Zscaler platform. As enterprises rapidly deploy IoT/OT devices across diverse environments, traditional firewall and VPN-based security models fail to meet the demands of today's mobile and distributed organizations, leaving devices exposed to cyber threats. Legacy approaches rely on costly infrastructure that cannot scale and cellular networks by themselves aren't designed to enforce Zero Trust principals resulting in security blind spots and expanding attack surfaces.

Partnering with Telcos to Build a Foundation for Zero Trust Security at Scale: Zscaler partners with leading telecommunications companies to bring advanced Zero Trust security to cellular-connected devices. By leveraging the Zscaler Zero Trust Exchange platform with telecom infrastructure, Zscaler Cellular delivers secure, scalable, and seamless connectivity for IoT and OT devices. Through solutions like Zscaler Cellular and Zscaler Cellular Edge, and collaborations with providers such as Stacuity and BT, enterprises gain managed security services that address the unique challenges of securing distributed, cellular-connected environments.

These partnerships ensure organizations can extend Zero Trust principles across global cellular networks, reducing risks and enabling secure digital transformation at scale. Zscaler Cellular is available globally in August 2025. The solution is already in use by leading organizations including Sandvik and Maverick Transportation, with additional customers to be announced.
