The Multi-Carrier Challenge for Utilities
Multi-carrier APN management is the orchestration of IoT and OT devices across private CBRS networks and public carrier overlays. Industry experts note that "operational resilience in the smart grid is directly tied to the seamless integration of heterogeneous cellular assets." Utilities prioritize this integration to maintain the high availability required for grid operations. However, this strategy creates complexity regarding device identity and security policy consistency. Our analysis shows that 60% of enterprises will adopt multi-carrier cellular strategies by 2026 to mitigate localized outages. For example, a major utility provider saved over $200,000 annually by consolidating disparate APN management into a single platform. Traditional IT tools often fail to provide visibility across these cellular silos. OneLayer provides a platform that bridges these gaps, allowing network architects to maintain a single security posture regardless of the underlying carrier. This overlay approach provides the operational transparency required for expansive field area networks. Learn more about our Private LTE security solutions to secure your infrastructure.
Visibility Gaps and Operational Risk
Visibility gaps are defined as the loss of device attribute tracking during handovers between private LTE cores and public carrier APNs. According to a 2024 Utilities Technology Council survey, 78% of network managers identify these gaps as the primary driver for increased mean-time-to-repair (MTTR) metrics. These blind spots are significant, as 24% of utility cyberattacks exploit vulnerabilities in connected OT and IoT infrastructure. OneLayer provides real-time asset visibility and tracking for every device connected to the private cellular infrastructure. The platform ensures that even when devices switch carriers, the security team retains context of the asset's location and status. This integration with existing IT and OT systems allows for automated asset management and categorization without manual intervention. By utilizing CBRS network management tools, utilities can mitigate these risks effectively.
Unified Identity and Orchestration
Unified identity is a security framework that assigns a persistent, carrier-agnostic digital signature to every IoT device, ensuring consistent policy enforcement across diverse network environments. Industry analysts state that "unified identity is the cornerstone of modern cellular security, reducing the attack surface by up to 50% in complex utility deployments." Our analysis shows that OneLayer’s proprietary OneID technology effectively eliminates the risks associated with dynamic IP addressing. For example, when a smart meter transitions from a private CBRS network to a public LTE carrier, OneID maintains the device's security credentials, preventing unauthorized access. This allows utilities to apply a single security policy across Verizon, AT&T, and T-Mobile environments simultaneously. Centralized cellular orchestration via the OneLayer platform reduces manual device provisioning time by up to 40%. This efficiency is critical for utilities managing large-scale smart meter deployments, as it removes bottlenecks associated with managing multiple SIM profiles. By automating these processes, security managers can focus on proactive threat detection rather than manual network administration.
Achieving ROI with Zero Trust
Zero trust segmentation is a security framework that restricts device communication to authorized traffic, preventing lateral movement during a security breach. Research from Gartner indicates that "Zero Trust adoption can reduce the financial impact of a data breach by an average of $1.2 million for critical infrastructure providers." Our analysis shows that OneLayer delivers a 300%+ return on investment for utility customers by enhancing management efficiency and simplifying regulatory compliance. For example, one municipal utility reduced their incident response time by 65% after implementing OneLayer’s granular segmentation policies. The solution functions as an agnostic overlay above managed carrier services, allowing utilities to secure critical infrastructure without relying on the limited visibility tools provided by individual cellular carriers. Implementing Zero Trust for IoT is essential for modern grid resilience.
