TL;DR

Zscaler Cellular extends Zero Trust security to cellular-connected IoT and mobile devices by inserting a control layer between SIM cards and mobile networks, eliminating visibility gaps.
Traditional cellular connectivity operates as a "black box" with no visibility into traffic or control over how devices access applications, creating security and compliance risks.
The platform ensures all traffic from cellular devices—vehicles, industrial IoT, phones—passes through Zscaler policy enforcement before reaching destination applications, providing unified global security control.

Summary

Nathan Howe, who leads innovation at Zscaler, introduces Zscaler Cellular, a new platform designed to secure cellular-connected IoT and mobile devices. The presentation contrasts traditional cellular connectivity—where devices like vehicles, solar panels, wind farms, and phones connect through mobile networks as a "black box" with no visibility or control—with Zscaler's approach. Zscaler Cellular positions a security control layer directly above the mobile network, ensuring all traffic from SIM-connected devices passes through Zscaler's policy enforcement before reaching destination applications. This architecture extends Zscaler's existing Zero Trust Exchange capabilities (ZIA and ZPA) to cellular connectivity, providing organizations with unified policy control across all cellular-connected assets globally. The solution addresses visibility gaps, unauthorized access risks, and data misuse concerns inherent in traditional cellular connectivity models, enabling businesses to protect IoT deployments, mobile workforces, and connected infrastructure with consistent security policies regardless of location or mobile network operator.

Key Quotes

0:29 "Maybe it's a vehicle, maybe it's an energy farm like solar panels or a wind farm."
1:04 "You don't know what's going on, you don't know what information is being used or misused."
1:46 "Zscaler sits at a layer directly above it, meaning that every single thing coming in and out of that SIM, everything goes through the control layer that Zscaler has built."
