Onboard every device securely, observe your network in real time, and protect what standard security tools miss.
The Platform
OneLayer Bridge connects your cellular network to the enterprise systems you already run. It gives you visibility and asset management for every connected device, secure onboarding and Zero Trust verification for every new one, detection and response for the threats standard tools miss, and connectivity troubleshooting that finds the root cause in seconds.
Private Cellular Security Platform
Verify and activate every device in minutes, no specialist required, so your operations team owns onboarding end to end.
See every device on your network, including what's hidden behind field routers, and catch operational issues before they escalate.
Detect SIM swaps, rogue devices, and lateral movement in real time, then enforce Zero Trust access at the cellular edge.
Onboard Every Device
Automatically enriches your CMDB with live device identity data
Every device is verified and policy-bound before it reaches production — no manual steps, no specialist queue.
Bulk provisioning replaces carrier portal workflows so your team activates full device batches without filing a ticket.
Every device is authenticated and segmented based on verified identity, not assumed trust from network position.
Device records and policy context flow automatically into your existing systems the moment a device connects.
Observe Every Device
Uncovers the 30–40% of devices existing tools typically miss
A live, fingerprinted inventory of every device on your private cellular network — including those your other tools have never seen.
Every device behind every field router discovered, classified, and added to your inventory automatically.
Continuous visibility into connection quality, device behavior, and network events across your entire private cellular deployment.
Operational anomalies and cost inefficiencies surfaced automatically, so your team acts on what matters before it becomes a problem.
Cellular network events and device context flow directly into your NOC, SIEM, and monitoring tools without manual export.
When a device goes dark, OneLayer pinpoints the cause in plain language — no signaling expertise required.
What Our Customers Are Saying
Our partnership with OneLayer allows us to scale and secure all of the devices on our network so we can effectively and efficiently expand network utilization. OneLayer's Bridge platform gives us control of connected assets on our LTE network and provides essential tools to better manage and secure our network as usage expands.
Protect Every Device
NGFW policy extended to Palo Alto, Fortinet, Cisco, and Check Point
Policy enforcement and segmentation built on verified device identity, so only authorized devices get access to the resources they're permitted to reach.
Suspicious device behavior, unauthorized connections, and policy violations detected automatically and surfaced with the context your team needs to act.
Firewall, SIEM, and security stack integrations that give your existing tools the private cellular device context they've always been missing.
Ecosystem
OneLayer Bridge integrates directly with the private cellular cores, security tools, and enterprise systems your team already operates. No rip-and-replace, no parallel infrastructure.

Every private and carrier cellular deployment is different. See how OneLayer Bridge applies to yours.
You run devices over a public carrier’s private APN. OneLayer aggregates every carrier into one view, so your team sees the actual device behind the SIM, not just the SIM.

Walk onto a plant floor that switched on private 5G last year and ask who built it. The answer is almost never one company. The radios came from one supplier, the core from another, the SIMs from a third, the routers from a fourth, and a system integrator put the pieces together. Now ask the […]

The storm has passed, but the substation still hasn’t heard from its reclosers. The private LTE site on the ridge lost commercial power hours ago, and its batteries are running down. The carrier tower the cellular routers were set to roam onto went dark in the same storm, on the same grid. Inside the cabinet, […]

The Card Everyone Trusts Can Give Orders In August 2026, researchers from the University of Birmingham and Fuzzware presented CATana, a study of SIM-originating AT commands, at USENIX WOOT ’26. They tested 26 devices and showed that a SIM card built or modified by an attacker can make a cellular modem run code, leak files, […]
