OneLayer

OneLayer is a cybersecurity and network management company focused on securing and managing private cellular networks such as private Long Term Evolution (LTE) and 5G for enterprise environments.

• Security and visibility platform for private LTE/5G networks (network security)
• Asset identification and context mapping across cellular-connected devices and Operational technology (OT) (OT security)
• Policy enforcement, access control, and segmentation for cellular network traffic (network access control)
• Integration with existing enterprise IT and security tooling for unified monitoring and workflows (security operations)
• Support for industrial and mission-critical deployments using private cellular infrastructure in sectors such as manufacturing, logistics, and utilities (operational networks)

More About OneLayer

OneLayer focuses on securing and managing enterprise private cellular networks, including private LTE and 5G deployments used in industrial campuses, logistics hubs, utilities, and other operational environments. Its platform is designed to provide network visibility, asset awareness, and policy control for devices and systems that connect over private cellular infrastructure rather than traditional Wi‑Fi or wired networks.

The company’s offering can be categorized as a network security and Network Access Control (NAC) solution tailored to cellular technologies. It typically sits alongside or integrates with the private cellular core and Radio Access Network (RAN), enabling enterprises to identify devices, understand their roles and communication patterns, and enforce access policies on cellular-connected endpoints. This covers a range of OT, Internet of Things (IoT) devices, and other equipment that relies on LTE or 5G connectivity in production sites and field deployments.

From an architectural perspective, OneLayer’s platform incorporates concepts familiar from IP networking and enterprise NAC into the cellular domain. It uses cellular network context, such as Subscriber Identity Module (SIM) profiles, subscriber identifiers, and radio information, combined with IP-level data, to create an inventory and security posture view of devices. The platform then applies segmentation and policy enforcement, comparable to approaches used in traditional Local Area Network (LAN) and Wi‑Fi security tools, but mapped to private LTE/5G network constructs. This supports use cases such as isolating critical OT systems, restricting access based on device type or role, and correlating cellular activity with enterprise security events.

OneLayer also emphasizes integration with existing enterprise IT and security ecosystems. Its platform is positioned to connect with tools such as Security Information and Event Management (SIEM) systems, firewalls, and asset management solutions, allowing private cellular networks to be monitored and governed using workflows that are already in place for other parts of the network. By providing a bridge between telecom-grade cellular infrastructure and enterprise security practices, the company enables organizations to apply consistent policies and oversight across wired, Wi‑Fi, and private LTE/5G environments.

In a directory or marketplace taxonomy, OneLayer aligns with categories including private cellular security, NAC for LTE/5G, OT and IoT security for industrial networks, and network visibility and asset intelligence for operational environments. Its focus on private LTE and 5G deployments positions it for enterprises that are adopting cellular connectivity for production systems and require security controls and observability that match existing IT security standards.
