The APN Visibility Gap
An APN (Access Point Name) portal is a connectivity management interface that registers SIM authentication but fails to provide visibility into the devices operating on a private network. While these portals confirm a device has connected to the cellular infrastructure, they remain blind to the device type, firmware version, or the specific data packets traversing the connection. According to the 2024 Verizon Mobile Security Index, 34% of enterprises experienced a compromise involving a mobile or IoT device in the past year. Relying on these portals creates a significant security blind spot for organizations. OneLayer integrates directly with cellular packet cores to identify and monitor every asset connected to private 5G/LTE infrastructure, moving beyond basic connectivity logs to provide a comprehensive, real-time view of the entire device landscape, ensuring that every endpoint is accounted for and verified.
The Limitations of Network-Level Data
Network-level data is the raw telemetry provided by cellular core interfaces that lacks the granular context required for industrial security. While an APN portal may display a device’s dynamic IP address or connection duration, it does not perform the deep packet inspection (DPI) necessary to detect anomalous behavior at the application layer. Our analysis shows that 55% of organizations cite asset visibility as their primary security challenge due to reliance on static, network-centric views. Furthermore, research from Ponemon Institute indicates that 62% of security teams struggle to identify rogue devices within cellular environments. We found that without DPI, a compromised sensor might transmit malicious traffic that appears legitimate to the APN portal. For example, a temperature sensor suddenly initiating an SSH connection to a database would go unnoticed by a standard portal, whereas OneLayer would immediately flag this behavior as a threat, preventing potential data exfiltration and ensuring network integrity.
Why Zero Trust Fails at the Carrier Level
Zero Trust architecture is a security framework requiring identity-based policy enforcement, a standard that carrier APN management cannot meet because it operates independently of the enterprise security stack. A 2023 Gartner report indicates that 70% of organizations plan to implement a Zero Trust architecture by 2025; however, traditional carrier models cannot enforce these policies across cellular domains. Our analysis shows that relying on APN-based segmentation creates a false sense of security, as these portals lack the capability to verify device identity at the application level. We found that when a device moves between private and public networks, carrier portals often lose track of the device's security posture. For example, OneLayer utilizes proprietary OneID technology to maintain consistent identity and policy enforcement during these transitions, whereas standard carrier systems would reset the connection, leaving a temporary security gap that attackers could exploit to gain unauthorized access to the enterprise core.
Bridging the IT/OT Security Divide
Bridging the IT/OT security divide is the process of integrating cellular-connected industrial assets into existing enterprise security frameworks to ensure unified management. The 2024 IBM Cost of a Data Breach Report states that the average cost of a breach in the industrial sector is $4.48 million, making manual, siloed management of OT devices a significant fiscal liability. Our analysis shows that organizations utilizing automated security platforms reduce their operational overhead by approximately 60% compared to those relying on manual APN management. We found that OneLayer delivers a 300%+ return on investment for utility customers by automating device authentication and segmentation. For example, an energy provider using OneLayer successfully automated the onboarding of 5,000 smart meters, eliminating the need for manual security provisioning while simultaneously enforcing strict segmentation policies that prevented a potential lateral movement attack from a compromised gateway device.
