As enterprises across manufacturing, energy, utilities, and critical infrastructure deploy private cellular networks to power digital transformation, they inherit a structural blind spot: cellular networks were designed to identify subscribers, not devices. This leaves organizations with no native visibility, no Zero Trust enforcement, and no way to detect cellular-specific threats.
OneLayer closes this gap with a purpose-built platform that transforms private cellular networks into fully manageable, enterprise-grade secure environments. Already deployed with 13 utilities, including Evergy, WEC Energy Group, Southern Linc, and TECO, as well as Fortune 100 and 500 mining and manufacturing operators globally, OneLayer is setting the emerging industry standard for private network security.
The Blind Spot Built Into Cellular Networks
Cellular networks were designed for mobile network operators whose primary asset is the subscriber, identified by IMSI, not the device. This architectural assumption leaves enterprises blind to what is actually operating on their OT and IIoT infrastructure. Devices connecting via cellular routers or adapters are invisible to standard tooling, creating unmanaged blind spots in asset inventory across critical environments.
Zero Trust Network Access requires reliable, persistent device identity, but in cellular environments the traditional identifiers, SIM cards and IMEIs, are weak. SIM cards can be swapped between devices, and cellular routers obscure the devices behind them. Without accurate device context, network segmentation is reduced to static, APN-level policies that are coarse, error-prone, and vulnerable to misconfiguration.
Detecting security incidents specific to cellular networks, SIM swapping, unauthorized device manufacturers, IMEI spoofing, abnormal radio behavior, requires cellular expertise that enterprise IT and OT teams typically lack. Traditional security tools cannot interpret cellular-layer signals, leaving this attack surface unmonitored.
Turning Radio Signals Into a Device Identity
OneLayer was purpose-built to solve these challenges. The platform integrates directly with the cellular network core, using SPAN to monitor attach requests, radio capabilities, handovers, and other cellular-layer signals. From this data, OneLayer builds a comprehensive and persistent device fingerprint called ONEID by correlating all available identifiers: IMSI, IP address, MAC address, APN, radio attributes, and behavioral signals.
- Tracks every device holistically, even when SIM cards are swapped or devices connect through cellular routers and adapters, eliminating the blind spots that exist in every private cellular deployment today.
- Enforces Zero Trust micro-segmentation, context-based access controls beyond static APN-level segmentation, integrating with Palo Alto Networks, Fortinet, and Check Point firewalls.
- Detects cellular-specific threats in real time, SIM swaps, unauthorized manufacturers, device modification, abnormal radio behavior, and policy violations, threats IT and telecom tools cannot detect.
- Automates device onboarding at scale, zero-touch onboarding scaling from dozens to thousands of devices without bottlenecks.
The platform is fully vendor-agnostic, integrating with Nokia, Ericsson, Palo Alto Networks, Fortinet, Check Point, Claroty, Cradlepoint, Digi, MultiTech, ServiceNow, and SolarWinds.

One Tool Catches What Nothing Else Sees
During a proof-of-value with a major European manufacturer, OneLayer detected a banned-manufacturer device operating deep inside a sensitive OT network segment. An employee had removed a SIM from a Level 1 router and inserted it into a personal phone, breaking Purdue model adherence and introducing an unauthorized device into the OT communications network. No other tool on the network caught it.
A New Category, Now Being Validated by the Market
OneLayer is pioneering a new category of enterprise security: device-centric security, visibility, and orchestration for private LTE/5G networks. Before OneLayer, there was no vendor-agnostic solution bridging the gap between enterprise IT/OT security practices and private cellular infrastructure.
Major security and infrastructure vendors are now entering the market mirroring OneLayer’s messaging, validating both the problem and the approach. OneLayer has been mentioned in multiple Gartner Hype Cycles, named a 2024 Gartner Cool Vendor, and featured in Forrester reports. Its vendor-agnostic model lowers the barrier for enterprises to secure their cellular environments regardless of their existing vendor stack, with the potential to set the standard for how private cellular networks are managed and secured globally.
Why Wi-Fi’s Weak Spot Needed a Cellular-Native Fix
Private LTE and 5G are increasingly the network technology of choice for industries undergoing digital transformation, chosen for coverage, reliability, low latency, and support for OT/IIoT workloads that Wi-Fi cannot serve. However, cellular technology introduces a structural security gap: no native device identity layer, no enterprise-grade access controls, and no built-in threat detection.
OneLayer integrates at the cellular core level, interpreting telecom-layer signals such as attach requests, radio capabilities, and handovers, and translating them into actionable enterprise security context. This works across all cellular technologies, 5G SA, 5G NSA, LTE, and CBRS, and all major core vendors, purpose-built for how cellular networks actually function.
