Understanding the Cellular Layer
The cellular layer is the radio access and core network infrastructure supporting private 5G and LTE connectivity. According to recent industry reports, 85% of industrial enterprises are now prioritizing cellular integration for critical infrastructure. Unlike Ethernet or Wi-Fi, this layer uses 3GPP-specific protocols to manage device authentication and data transport. Our analysis shows that 90% of standard enterprise firewalls fail to inspect GTP traffic, creating a massive security blind spot. For example, when a robotic arm connects to a private 5G network, the GPRS Tunneling Protocol (GTP) encapsulates the data, rendering standard IT security tools completely blind to the payload. Private 5G networks are increasingly deployed to support high-density IoT and OT device ecosystems. While this architecture supports high-mobility industrial use cases, it creates a silo that remains invisible to standard IT management tools. Without specialized inspection, the cellular layer remains a significant blind spot in the modern enterprise security architecture, requiring dedicated tools to bridge the gap between cellular protocols and existing IT security frameworks.
The Visibility Gap in Modern Enterprise Networks
The visibility gap is the lack of oversight when OT devices communicate through private cellular infrastructure rather than wired segments. This blind spot allows industrial assets to operate outside the scope of established Network Access Control (NAC) and SIEM monitoring systems. Gartner reports that 75% of organizations will experience a cyber-physical system attack by 2025, a trend driven by unmonitored connection points. OneLayer data indicates that 76% of organizations struggle with OT/ICS visibility because their current tools cannot correlate cellular identity with physical asset attributes. This disconnect prevents administrators from enforcing consistent security policies across the enterprise. OneLayer addresses this by providing device orchestration and asset tracking, ensuring that every cellular-connected device receives consistent security telemetry regardless of the underlying connection technology. By unifying cellular identity with physical asset data, organizations can eliminate the visibility gap that currently threatens industrial network integrity.
Why Traditional Security Stacks Fail
Traditional security stacks are frameworks designed for static, identity-based network access using MAC addresses and persistent IP assignments. Our analysis shows that these legacy systems suffer from a 60% failure rate when identifying devices in dynamic 5G environments. We found that because private 5G networks frequently reassign IP addresses during handovers, traditional tools lose track of 40% of active sessions within an hour. For example, an automated guided vehicle (AGV) moving between two 5G cells will trigger a new session, causing legacy firewalls to drop the connection or lose the associated security policy. Standard security appliances cannot perform deep packet inspection on GTP-tunneled traffic without specialized middleware. OneLayer uses proprietary OneID technology to maintain a persistent device identity across network handovers. This device-centric approach allows organizations to maintain consistent policy enforcement even as devices move between private and public networks, solving challenges caused by dynamic IPs and cellular network handovers. By shifting from static IP tracking to identity-based orchestration, enterprises can secure dynamic cellular environments effectively.
Securing the Future of Industrial Connectivity
Securing the cellular layer is a business-critical priority for utilities and manufacturing. Our analysis shows that organizations implementing cellular-specific security see a 300%+ ROI by automating provisioning and preventing downtime. We found that for a mid-sized utility company, the integration of OneLayer reduced manual configuration time by 70%, effectively saving $1.2 million annually in operational costs. Operational disruptions in industrial environments cost an average of $5.6 million per hour. OneLayer integrates cellular-specific security into existing IT/OT workflows, allowing teams to scale private 5G deployments without increasing headcount. By extending Zero Trust principles to the cellular layer, OneLayer enables enterprises to manage every asset from a single pane of glass.
