This discussion addresses the critical visibility and security gaps in private LTE and 5G networks. While traditional IT environments rely on device-centric IP identifiers, cellular networks were originally designed for telecommunications providers to track SIM cards for billing rather than identifying the hardware itself. This disconnect leaves IT administrators with limited data, such as IMSI or IMEI numbers, which fails to provide the necessary context for modern enterprise security and operational policies. OneLayer introduces its OneLayer Bridge solution to solve this fundamental problem by allowing enterprises to see and manage every device connected to their private cellular network, including those hidden behind SIM-enabled routers.
The core value of the OneLayer platform lies in its “actionable insights,” which transform raw cellular visibility into automated security outcomes. By integrating with the cellular core and monitoring traffic via network taps or span ports, OneLayer detects behavioral anomalies such as unauthorized SIM swaps or unusual data spikes that might indicate a compromised SCADA device. Because OneLayer has all the keys and speaks the language of the cellular core, it can correlate encrypted radio control data with the actual payload, providing a level of oversight that standard security tools cannot achieve. When an issue is detected, the system can automatically trigger alerts or move devices into “untrustworthy” groups within an enterprise’s existing security infrastructure.
To ensure the solution is both scalable and IT-friendly, OneLayer utilizes a two-part Kubernetes-based architecture consisting of a local “edge” component for low-latency monitoring and a centralized “bridge” for management. Rather than forcing firewall administrators to allow a third-party app to change core policies directly, OneLayer integrates with platforms like Palo Alto Networks using Dynamic Address Groups (DAGs). This allows OneLayer to push real-time identity and behavioral updates to the firewall, which then applies the appropriate pre-defined security rules. By bridging the gap between cellular protocols and standard IT enforcement engines, OneLayer enables enterprises to manage private 5G security with the same granularity and confidence they apply to their traditional wired and Wi-Fi networks.
