IXT, a Norway-based mobile virtual network operator, is moving to integrate cybersecurity more deeply into cellular connectivity, announcing a partnership with Zscaler to embed Zero Trust Network Access directly into its IoT platform. The initiative reflects a broader shift away from virtual private networks, or VPNs, which have long underpinned remote access but are increasingly seen as ill-suited to large-scale device environments. Instead, organisations are adopting Zero Trust models that verify every connection and limit access by default. By embedding Zscaler’s technology at the SIM level, IXT is targeting a persistent weakness in IoT deployments: securing large fleets of devices that cannot run conventional security software and are often deployed in remote or industrial settings. “VPNs were designed to connect users on laptops to corporate networks. They were never built for thousands of headless devices in energy grids, water treatment plants and factory floors,” said Henning Solberg, Chief Technology Officer and Co-Founder of IXT. “With this integration, we bring the same Zero Trust architecture that Zscaler delivers to Fortune 500 IT environments directly to OT and IoT devices over cellular.” Under the arrangement, device traffic is routed through Zscaler’s Cloud-based Zero Trust Exchange, where it is inspected and policy-controlled before reaching its destination. The model removes the need for inbound network exposure and avoids the broad access permissions typically associated with VPNs. The timing aligns with tightening regulation in Europe. The NIS2 Directive, now being transposed into national law, imposes stricter requirements on operators of critical infrastructure to secure networks, including connected devices. It also introduces direct accountability for senior management. “For organisations facing NIS2 compliance obligations, this integration is designed to support key requirements with a reduced attack surface, no VPN dependencies, full traffic inspection, and audit-ready controls, all from a single SIM,” Solberg said. The challenge is particularly
