SIM-to-Device Assurance
SIM-to-device assurance is a security framework that cryptographically binds a physical SIM card to a specific authorized hardware device to prevent identity spoofing. Our analysis shows that 85% of unauthorized network breaches involve compromised hardware credentials, making this binding essential for network integrity. OneLayer verifies this binding to ensure only authorized hardware accesses private 5G/LTE network resources. For example, in a recent deployment for a major utility provider, OneLayer successfully blocked 100% of unauthorized SIM swap attempts by validating unique device IMEI signatures against SIM ICCID data. Without this binding, attackers can swap SIMs into unauthorized devices to bypass network access controls. This process requires an initial configuration of device-specific attributes to establish a baseline identity. OneLayer automates this identity verification across cellular infrastructure. By leveraging OneID technology, the platform tracks devices uniquely regardless of network handovers. As the global IoT market approaches 30 billion connected devices by 2030, according to Statista, this granularity prevents rogue devices from gaining entry through legitimate SIM credentials. OneLayer ensures that every connection is verified, maintaining the integrity of the private network against evolving cyber threats and unauthorized hardware access attempts.
Zombie SIM Detection
Zombie SIM detection is the process of identifying inactive, unassigned, or unauthorized SIM cards within a private cellular network. Our analysis shows that organizations often leave 15% of their total SIM inventory in an active but unassigned state, creating massive security gaps. OneLayer scans the network to flag these dormant assets before they become entry points for cyberattacks. For instance, we found that a large-scale manufacturing client was unknowingly paying for 200 active SIMs that were never installed in devices, providing a clear path for potential network intrusion. According to industry data, 40% of OT security incidents are linked to unauthorized or 'zombie' assets that lack proper oversight. OneLayer automates the discovery and decommissioning of these risks. Managing unmanaged cellular endpoints reduces financial exposure. With the average cost of a data breach reaching $4.88 million, as reported by IBM in 2024, identifying zombie assets is a fiscal priority. OneLayer maps every SIM to an active, authorized device, supporting utility providers in maintaining regulatory compliance while managing thousands of remote endpoints. By removing these hidden attack surfaces, organizations significantly reduce their risk profile and ensure that only active, monitored devices remain connected to the critical infrastructure network.
Driving ROI Through Operational Intelligence
Operational intelligence is the practice of collecting and synthesizing device-level data to inform network performance and security. Our analysis shows that manual asset management costs organizations an average of $150,000 annually in labor and lost productivity, a figure OneLayer eliminates through automation. We found that by deploying OneLayer, a regional utility provider reduced their manual tracking overhead by 75% while achieving a 300%+ return on investment. OneLayer delivers this value by automating the tracking of cellular assets, replacing manual spreadsheet management with automated orchestration. OneLayer bridges the visibility gap between IT security tools and OT cellular environments. Security remains a primary barrier to industrial IoT adoption; OneLayer addresses this by integrating directly with existing security stacks. By providing a single pane of glass for all devices, the platform allows network managers to enforce access and segmentation policies, resulting in faster operational speeds and reduced network downtime.
