Zscaler launches Zscaler Cellular: a mobile Zero Trust solution that securely connects IoT and OT devices to mobile networks and underlying security infrastructure via a SIM card.
Zscaler launches Zscaler Cellular. This is an extension of the Zero Trust Exchange platform, which aims to securely connect IoT and OT devices using a zero trust approach. With the new solution, companies no longer need separate software or VPN connections.
Operation
With Zscaler Cellular, IoT and OT devices receive their own SIM card to connect to public 4G or 5G networks. The data traffic is immediately directed to a Zscaler Cellular Edge, where it is inspected. Zscaler Cellular then forwards the traffic to the Zero Trust Exchange platform, where zero trust policies are applied and enforced.
Through this approach, each device remains isolated on its own network segment. Administrators monitor network traffic via central dashboards, allowing them to enforce policies and mitigate risks. A security issue with one device will not lead to broader network access for a hacker.

Traditional firewalls and VPN solutions do not offer the same level of protection and are deemed insufficient by Zscaler for modern IoT and OT environments. Companies are increasingly using devices that operate mobile and distributed. By applying zero trust to mobile networks, Zscaler aims to reduce vulnerabilities.
Availability
Zscaler collaborates with telecom companies to roll out the solution globally. This allows organizations to combine Zero Trust security with existing telecom infrastructure, making it easier to securely connect and manage devices. Zscaler Cellular will be available worldwide from August 2025.
